== Install and configuration ==
* Backing up a ntfs-3g mount with <code>rsync_bpc</code> keeps transfering all files. See below for details.

: Solution: Use <code>tar</code> method instead?
=== ntfs-3g backups ===
When backing up ntfs-3g shares, '''the option <code>--links</code> and <code>--hard-links</code> must be removed from <code>RsyncArgs</code> and <code>RsyncRestoreArgs</code>''' (see troubleshooting section below)

Since these options are common to a same client, one must create a separate backuppc client if a given physical host contains both ntfs-3g and non-ntfs-3g partitions.
In that case, one client will match the name of the host, where others will have different names. For these clients, set the variable <code>ClientNameAlias</code> to the name of the physical host in the client configuration.

== Install on Windows ==
<source lang=text>
Reference: http://www.systemajik.com/blog/setting-up-backuppc-on-windows/

Download and install cygwin-rsync from http://sourceforge.net/projects/backuppc/files/cygwin-rsyncd/3.0.9.0/
Edit c:\rsyncd\rsyncd.conf
Edit c:\rsyncd\rsyncd.secrets

Update the firewall rules
Test connection with telnet from backuppc server

Create exclusion list
- Make sure we exclude locked file and junction
- To get list of junctions:
dir /aL /s > JunctionPoints.txt
Check backuppc charset setting

Is this a new installation or upgrade for BackupPC? If this is
an upgrade please tell me the full path of the existing BackupPC
configuration file (eg: /etc/BackupPC/config.pl). Otherwise, just
hit return.

--> Full path to existing main config.pl []?

I found the following locations for these programs:

bzip2 => /opt/bin/bzip2
cat => /opt/bin/cat
df => /opt/bin/df
gtar/tar => /opt/bin/tar
gzip => /opt/bin/gzip
hostname => /bin/hostname
nmblookup => /usr/syno/bin/nmblookup
par2 => /opt/bin/par2
perl => /opt/bin/perl
ping => /bin/ping
rrdtool => /opt/bin/rrdtool
rsync => /opt/bin/rsync
rsync_bpc => /usr/local/bin/rsync_bpc
sendmail =>
smbclient => /usr/syno/bin/smbclient
split => /opt/bin/split
ssh/ssh2 => /usr/syno/bin/ssh

--> Are these paths correct? [y]?

Please tell me the hostname of the machine that BackupPC will run on.

--> BackupPC will run on host [Mnemosyne]?

BackupPC should run as a dedicated user with limited privileges. You
need to create a user. This user will need read/write permission on
the main data directory and read/execute permission on the install
directory (these directories will be setup shortly).

The primary group for this user should also be chosen carefully.
The data directories and files will have group read permission,
so group members can access backup files.

--> BackupPC should run as user [backuppc]?

Please specify an install directory for BackupPC. This is where the
BackupPC scripts, library and documentation will be installed.

--> Install directory (full path) [/usr/local/BackupPC]? /opt/local/backuppc

Please specify a data directory for BackupPC. This is where all the
PC backup data is stored. This file system needs to be big enough to
accommodate all the PCs you expect to backup (eg: at least several GB
per machine).

--> Data directory (full path) [/data/BackupPC]? /opt/var/lib/backuppc

BackupPC has SCGI and CGI perl interfaces that run under Apache. You need
to pick which one to run.

For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
which handles the requests. This allows Apache to run as a different user as
backuppc. To use SCGI you need to set SCGIServerPort to any spare
non-privileged TCP port number. A negative value disables SCGI.

Important security warning!! The SCGIServerPort must not be accessible by
anyone untrusted. That means you can't allow untrusted users access to the
BackupPC server, and you should block the SCGIServerPort TCP port from
network access.

The traditional alternative is to use CGI. In this case, an executable needs
to be installed Apache's cgi-bin directory. This executable needs to run as
set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]?
--> CGI bin directory (full path, or empty for no CGI) []? /usr/syno/synoman/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them. They
should be placed somewhere under Apache's DocumentRoot. BackupPC
also needs to know the URL to access these images. Example:

Apache image directory: /var/www/htdocs/BackupPC
URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /usr/syno/synoman/backuppc
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

- install the binaries, lib and docs in /opt/local/backuppc,
- create the data directory /opt/var/lib/backuppc,
- create/update the config.pl file /etc/BackupPC/config.pl,
- optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /usr/syno/synoman/backuppc

Ok, it looks like we are finished. There are several more things you
will need to do:

- Browse through the config file, /etc/BackupPC/config.pl,
and make sure all the settings are correct. In particular,
you will need to set $Conf{CgiAdminUsers} so you have
administration privileges in the CGI interface.

- Edit the list of hosts to backup in /etc/BackupPC/hosts.

- Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
Please pay special attention to the security section.

- Verify that the CGI script BackupPC_Admin runs correctly. You might
need to change the permissions or group ownership of BackupPC_Admin.
If this is an upgrade and you are using mod_perl, you will need
to restart Apache. Otherwise it will have stale code.

- BackupPC should be ready to start. Don't forget to run it
as user backuppc! The installation also contains an
init.d/backuppc script that can be copied to /etc/init.d
so that BackupPC can auto-start on boot. This will also enable
administrative users to start the server from the CGI interface.
See init.d/README.

Enjoy!

Is this a new installation or upgrade for BackupPC? If this is
an upgrade please tell me the full path of the existing BackupPC
configuration file (eg: /etc/BackupPC/config.pl). Otherwise, just
hit return.

ssh/ssh2 => /usr/bin/ssh

--> Are these paths correct? [y]?

Please tell me the hostname of the machine that BackupPC will run on.

--> BackupPC will run on host [LaCie-CloudBox]?

BackupPC should run as a dedicated user with limited privileges. You
need to create a user. This user will need read/write permission on
the main data directory and read/execute permission on the install
directory (these directories will be setup shortly).

The primary group for this user should also be chosen carefully.
The data directories and files will have group read permission,
so group members can access backup files.

--> BackupPC should run as user [backuppc]?

Please specify an install directory for BackupPC. This is where the
BackupPC scripts, library and documentation will be installed.

--> Install directory (full path) [/usr/local/BackupPC]? /opt/local/backuppc

Please specify a data directory for BackupPC. This is where all the
PC backup data is stored. This file system needs to be big enough to
accommodate all the PCs you expect to backup (eg: at least several GB
per machine).

--> Data directory (full path) [/data/BackupPC]? /opt/var/lib/backuppc

BackupPC has SCGI and CGI perl interfaces that run under Apache. You need
to pick which one to run.

For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
which handles the requests. This allows Apache to run as a different user as
backuppc. To use SCGI you need to set SCGIServerPort to any spare
non-privileged TCP port number. A negative value disables SCGI.

Important security warning!! The SCGIServerPort must not be accessible by
anyone untrusted. That means you can't allow untrusted users access to the
BackupPC server, and you should block the SCGIServerPort TCP port from
network access.

The traditional alternative is to use CGI. In this case, an executable needs
to be installed Apache's cgi-bin directory. This executable needs to run as
set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]?
--> CGI bin directory (full path, or empty for no CGI) []? /opt/lib/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them. They
should be placed somewhere under Apache's DocumentRoot. BackupPC
also needs to know the URL to access these images. Example:

Apache image directory: /var/www/htdocs/BackupPC
URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /opt/local/backuppc/cgi-bin
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

- install the binaries, lib and docs in /opt/local/backuppc,
- create the data directory /opt/var/lib/backuppc,
- create/update the config.pl file /etc/BackupPC/config.pl,
- optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /opt/lib/backuppc

Ok, it looks like we are finished. There are several more things you
will need to do:

- Browse through the config file, /etc/BackupPC/config.pl,
and make sure all the settings are correct. In particular,
you will need to set $Conf{CgiAdminUsers} so you have
administration privileges in the CGI interface.

- Edit the list of hosts to backup in /etc/BackupPC/hosts.

- Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
Please pay special attention to the security section.

- Verify that the CGI script BackupPC_Admin runs correctly. You might
need to change the permissions or group ownership of BackupPC_Admin.
If this is an upgrade and you are using mod_perl, you will need
to restart Apache. Otherwise it will have stale code.

- BackupPC should be ready to start. Don't forget to run it
as user backuppc! The installation also contains an
init.d/backuppc script that can be copied to /etc/init.d
so that BackupPC can auto-start on boot. This will also enable
administrative users to start the server from the CGI interface.
See init.d/README.

Enjoy!

set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]?
--> CGI bin directory (full path, or empty for no CGI) []? /opt/lib/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them. They
should be placed somewhere under Apache's DocumentRoot. BackupPC
also needs to know the URL to access these images. Example:

Apache image directory: /var/www/htdocs/BackupPC
URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /opt/local/backuppc/cgi-bin
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

- install the binaries, lib and docs in /opt/local/backuppc,
- create the data directory /shares/backuppc,
- create/update the config.pl file /opt/etc/backuppc/config.pl,
- optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /opt/lib/backuppc

Ok, it looks like we are finished. There are several more things you
will need to do:

- Browse through the config file, /opt/etc/backuppc/config.pl,
and make sure all the settings are correct. In particular,
you will need to set $Conf{CgiAdminUsers} so you have
administration privileges in the CGI interface.

- Edit the list of hosts to backup in /opt/etc/backuppc/hosts.

- Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
Please pay special attention to the security section.

- Verify that the CGI script BackupPC_Admin runs correctly. You might
need to change the permissions or group ownership of BackupPC_Admin.
If this is an upgrade and you are using mod_perl, you will need
to restart Apache. Otherwise it will have stale code.

- BackupPC should be ready to start. Don't forget to run it
as user backuppc! The installation also contains an
init.d/backuppc script that can be copied to /etc/init.d
so that BackupPC can auto-start on boot. This will also enable
administrative users to start the server from the CGI interface.
See init.d/README.

Enjoy!

== Install BackupPC clients ==
Choices:
; rsyncd
: Can do a full backup w/o giving access to root. access can be restricted to read-only so that backup server cannot do damage to client if compromised. Requires setting up a server and install xinetd. Authentication is weak though, but not much a problem (files are already available on the backup server anyway). Quite simple to configure. I don't like xinetd/inetd though.
; ssh+rsync
: Login on client as user 'backuppc'. SSH private key on backuppc is password-less, but similar to storing a secret password in some file on the backup server. Root access on the client given via sudo, and restricted to run "rsync --server --sender *", such that to enforce read-only access. All traffic goes via ssh, and hence is encrypted. Strong authentication. A bit more complex to configure, but no xinetd, and no daemon.
: See http://www.systemajik.com/blog/setting-up-backuppc-on-ubuntu/ for more information.

ssh+rsync is more difficult to setup; also on the NAS, the backuppc does not have dedicated home directory. So we can't easily store .ssh/id_rsa.pub and .ssh/known_hosts file. Also, on Windows client, it seems the default solution is to use rsyncd. Also, I don't really need link encryption.

We choose '''rsyncd''':
* See https://help.ubuntu.com/community/rsync#Rsync_Daemon .
* http://www.systemajik.com/blog/setting-up-backuppc-on-ubuntu/ (for exclusion of some paths).

Install log:
<source lang="bash">
vi /etc/default/rsync
sudo apt-get install xinetd
vi /etc/xinetd.d/rsync
# service rsync
# {
# disable = no
# socket_type = stream
# wait = no
# user = root
# server = /usr/bin/rsync
# server_args = --daemon
# log_on_failure += USERID
# flags = IPv6
# }
sudo vi /etc/rsyncd.conf
# max connections = 2
# log file = /var/log/rsync.log
# timeout = 6000
#
# [share]
# comment = Public Share
# path = /home/share
# read only = yes
# list = yes
# uid = nobody
# gid = nogroup
# auth users = backuppc
# secrets file = /etc/rsyncd.secrets

# (Note: default timeout 300 is not enough for our NAS - we get child exited prematurely errors)

sudo vi /etc/rsyncd.secrets
# user:password
sudo chmod 600 /etc/rsyncd.secrets
sudo /etc/init.d/xinetd restart

# Testing
sudo rsync backuppc@hostname::share
</source>

== Benchmarks ==

Some statistics:

<source lang="text">

1 incr 3 0.0 0.0 -6.4% 201.8 199.1 1.3%
</source>

Performance not very good. Let's disable compression and do again. I get 1.25MB/s for first full backup.
When pinging nxl67170ux, I get my wlan0 address!
Let's disable WIFI and start again...

Install and configuration

ntfs-3g backups

When backing up ntfs-3g shares, the option --links and --hard-links must be removed from RsyncArgs and RsyncRestoreArgs (see troubleshooting section below)

Since these options are common to a same client, one must create a separate backuppc client if a given physical host contains both ntfs-3g and non-ntfs-3g partitions. In that case, one client will match the name of the host, where others will have different names. For these clients, set the variable ClientNameAlias to the name of the physical host in the client configuration.

Install on Windows

Reference: http://www.systemajik.com/blog/setting-up-backuppc-on-windows/

Download and install cygwin-rsync from http://sourceforge.net/projects/backuppc/files/cygwin-rsyncd/3.0.9.0/
Edit c:\rsyncd\rsyncd.conf
Edit c:\rsyncd\rsyncd.secrets

Update the firewall rules
Test connection with telnet from backuppc server

Create exclusion list
 - Make sure we exclude locked file and junction
 - To get list of junctions:
   dir /aL /s > JunctionPoints.txt
Check backuppc charset setting

Is this a new installation or upgrade for BackupPC?  If this is
an upgrade please tell me the full path of the existing BackupPC
configuration file (eg: /etc/BackupPC/config.pl).  Otherwise, just
hit return.

--> Full path to existing main config.pl []? 

I found the following locations for these programs:

    bzip2        => /opt/bin/bzip2
    cat          => /opt/bin/cat
    df           => /opt/bin/df

    split        => /opt/bin/split
    ssh/ssh2     => /usr/syno/bin/ssh

--> Are these paths correct? [y]? 

Please tell me the hostname of the machine that BackupPC will run on.

--> BackupPC will run on host [Mnemosyne]? 

BackupPC should run as a dedicated user with limited privileges.  You
need to create a user.  This user will need read/write permission on
the main data directory and read/execute permission on the install
directory (these directories will be setup shortly).

The primary group for this user should also be chosen carefully.
The data directories and files will have group read permission,
so group members can access backup files.

--> BackupPC should run as user [backuppc]? 

Please specify an install directory for BackupPC.  This is where the
BackupPC scripts, library and documentation will be installed.

--> Install directory (full path) [/usr/local/BackupPC]? /opt/local/backuppc

Please specify a data directory for BackupPC.  This is where all the
PC backup data is stored.  This file system needs to be big enough to
accommodate all the PCs you expect to backup (eg: at least several GB
per machine).

--> Data directory (full path) [/data/BackupPC]? /opt/var/lib/backuppc

BackupPC has SCGI and CGI perl interfaces that run under Apache.  You need
to pick which one to run.

For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
which handles the requests.  This allows Apache to run as a different user as
backuppc.  To use SCGI you need to set SCGIServerPort to any spare
non-privileged TCP port number.  A negative value disables SCGI.

Important security warning!!  The SCGIServerPort must not be accessible by
anyone untrusted.  That means you can't allow untrusted users access to the
BackupPC server, and you should block the SCGIServerPort TCP port from
network access.

The traditional alternative is to use CGI.  In this case, an executable needs
to be installed Apache's cgi-bin directory.  This executable needs to run as
set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]? 
--> CGI bin directory (full path, or empty for no CGI) []? /usr/syno/synoman/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them.  They
should be placed somewhere under Apache's DocumentRoot.  BackupPC
also needs to know the URL to access these images.  Example:

    Apache image directory:  /var/www/htdocs/BackupPC
    URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /usr/syno/synoman/backuppc
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

  - install the binaries, lib and docs in /opt/local/backuppc,
  - create the data directory /opt/var/lib/backuppc,
  - create/update the config.pl file /etc/BackupPC/config.pl,
  - optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /usr/syno/synoman/backuppc

Ok, it looks like we are finished.  There are several more things you
will need to do:

  - Browse through the config file, /etc/BackupPC/config.pl,
    and make sure all the settings are correct.  In particular,
    you will need to set $Conf{CgiAdminUsers} so you have
    administration privileges in the CGI interface.

  - Edit the list of hosts to backup in /etc/BackupPC/hosts.

  - Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
    Please pay special attention to the security section.

  - Verify that the CGI script BackupPC_Admin runs correctly.  You might
    need to change the permissions or group ownership of BackupPC_Admin.
    If this is an upgrade and you are using mod_perl, you will need
    to restart Apache.  Otherwise it will have stale code.

  - BackupPC should be ready to start.  Don't forget to run it
    as user backuppc!  The installation also contains an
    init.d/backuppc script that can be copied to /etc/init.d
    so that BackupPC can auto-start on boot.  This will also enable
    administrative users to start the server from the CGI interface.
    See init.d/README.

Enjoy!

Is this a new installation or upgrade for BackupPC?  If this is
an upgrade please tell me the full path of the existing BackupPC
configuration file (eg: /etc/BackupPC/config.pl).  Otherwise, just
hit return.

--> Full path to existing main config.pl []? 

I found the following locations for these programs:

    bzip2        => /opt/bin/bzip2
    cat          => /opt/bin/cat
    df           => /opt/bin/df
    gtar/tar     => /opt/bin/tar
    gzip         => /opt/bin/gzip
    hostname     => /bin/hostname
    nmblookup    => /usr/bin/nmblookup

    smbclient    => 
    split        => /opt/bin/split
    ssh/ssh2     => /usr/bin/ssh

--> Are these paths correct? [y]? 

Please tell me the hostname of the machine that BackupPC will run on.

--> BackupPC will run on host [LaCie-CloudBox]? 

BackupPC should run as a dedicated user with limited privileges.  You
need to create a user.  This user will need read/write permission on
the main data directory and read/execute permission on the install
directory (these directories will be setup shortly).

The primary group for this user should also be chosen carefully.
The data directories and files will have group read permission,
so group members can access backup files.

--> BackupPC should run as user [backuppc]? 

Please specify an install directory for BackupPC.  This is where the
BackupPC scripts, library and documentation will be installed.

--> Install directory (full path) [/usr/local/BackupPC]? /opt/local/backuppc

Please specify a data directory for BackupPC.  This is where all the
PC backup data is stored.  This file system needs to be big enough to
accommodate all the PCs you expect to backup (eg: at least several GB
per machine).

--> Data directory (full path) [/data/BackupPC]? /opt/var/lib/backuppc

BackupPC has SCGI and CGI perl interfaces that run under Apache.  You need
to pick which one to run.

For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
which handles the requests.  This allows Apache to run as a different user as
backuppc.  To use SCGI you need to set SCGIServerPort to any spare
non-privileged TCP port number.  A negative value disables SCGI.

Important security warning!!  The SCGIServerPort must not be accessible by
anyone untrusted.  That means you can't allow untrusted users access to the
BackupPC server, and you should block the SCGIServerPort TCP port from
network access.

The traditional alternative is to use CGI.  In this case, an executable needs
to be installed Apache's cgi-bin directory.  This executable needs to run as
set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]? 
--> CGI bin directory (full path, or empty for no CGI) []? /opt/lib/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them.  They
should be placed somewhere under Apache's DocumentRoot.  BackupPC
also needs to know the URL to access these images.  Example:

    Apache image directory:  /var/www/htdocs/BackupPC
    URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /opt/local/backuppc/cgi-bin
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

  - install the binaries, lib and docs in /opt/local/backuppc,
  - create the data directory /opt/var/lib/backuppc,
  - create/update the config.pl file /etc/BackupPC/config.pl,
  - optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /opt/lib/backuppc

Ok, it looks like we are finished.  There are several more things you
will need to do:

  - Browse through the config file, /etc/BackupPC/config.pl,
    and make sure all the settings are correct.  In particular,
    you will need to set $Conf{CgiAdminUsers} so you have
    administration privileges in the CGI interface.

  - Edit the list of hosts to backup in /etc/BackupPC/hosts.

  - Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
    Please pay special attention to the security section.

  - Verify that the CGI script BackupPC_Admin runs correctly.  You might
    need to change the permissions or group ownership of BackupPC_Admin.
    If this is an upgrade and you are using mod_perl, you will need
    to restart Apache.  Otherwise it will have stale code.

  - BackupPC should be ready to start.  Don't forget to run it
    as user backuppc!  The installation also contains an
    init.d/backuppc script that can be copied to /etc/init.d
    so that BackupPC can auto-start on boot.  This will also enable
    administrative users to start the server from the CGI interface.
    See init.d/README.

Enjoy!

an upgrade please tell me the full path of the existing BackupPC
configuration file (eg: /etc/BackupPC/config.pl).  Otherwise, just
hit return.

--> Full path to existing main config.pl []? 

I found the following locations for these programs:

    bzip2        => /opt/bin/bzip2
    cat          => /opt/bin/cat
    df           => /opt/bin/df
    gtar/tar     => /opt/bin/tar
    gzip         => /opt/bin/gzip
    hostname     => /bin/hostname
    nmblookup    => /usr/bin/nmblookup
    par2         => /opt/bin/par2
    perl         => /opt/bin/perl
    ping         => /bin/ping

    smbclient    => 
    split        => /opt/bin/split
    ssh/ssh2     => /usr/bin/ssh

--> Are these paths correct? [y]? 

Please tell me the hostname of the machine that BackupPC will run on.

--> BackupPC will run on host [LaCie-CloudBox]? 

BackupPC should run as a dedicated user with limited privileges.  You
need to create a user.  This user will need read/write permission on
the main data directory and read/execute permission on the install
directory (these directories will be setup shortly).

The primary group for this user should also be chosen carefully.
The data directories and files will have group read permission,
so group members can access backup files.

--> BackupPC should run as user [backuppc]? 

Please specify an install directory for BackupPC.  This is where the
BackupPC scripts, library and documentation will be installed.

--> Install directory (full path) [/usr/local/BackupPC]? /opt/local/backuppc

Please specify a data directory for BackupPC.  This is where all the
PC backup data is stored.  This file system needs to be big enough to
accommodate all the PCs you expect to backup (eg: at least several GB
per machine).

--> Data directory (full path) [/data/BackupPC]? /shares/backuppc

BackupPC has SCGI and CGI perl interfaces that run under Apache.  You need
to pick which one to run.

For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
which handles the requests.  This allows Apache to run as a different user as
backuppc.  To use SCGI you need to set SCGIServerPort to any spare
non-privileged TCP port number.  A negative value disables SCGI.

Important security warning!!  The SCGIServerPort must not be accessible by
anyone untrusted.  That means you can't allow untrusted users access to the
BackupPC server, and you should block the SCGIServerPort TCP port from
network access.

The traditional alternative is to use CGI.  In this case, an executable needs
to be installed Apache's cgi-bin directory.  This executable needs to run as
set-uid backuppc, or it can be run under mod_perl with Apache
running as user backuppc.

--> SCGI port (-1 to disable) [-1]? 
--> CGI bin directory (full path, or empty for no CGI) []? /opt/lib/backuppc

BackupPC's CGI and SCGI script need to display various PNG/GIF
images that should be stored where Apache can serve them.  They
should be placed somewhere under Apache's DocumentRoot.  BackupPC
also needs to know the URL to access these images.  Example:

    Apache image directory:  /var/www/htdocs/BackupPC
    URL for image directory: /BackupPC

The URL for the image directory should start with a slash.

--> Apache image directory (full path, or empty for no S/CGI) []? /opt/local/backuppc/cgi-bin 
--> URL for image directory (omit http://host; starts with '/', or empty for no S/CGI) []? /backuppc

Ok, we're about to:

  - install the binaries, lib and docs in /opt/local/backuppc,
  - create the data directory /shares/backuppc,
  - create/update the config.pl file /opt/etc/backuppc/config.pl,
  - optionally install the cgi-bin interface.

--> Do you want to continue? [y]?

Installing cgi script BackupPC_Admin in /opt/lib/backuppc

Ok, it looks like we are finished.  There are several more things you
will need to do:

  - Browse through the config file, /opt/etc/backuppc/config.pl,
    and make sure all the settings are correct.  In particular,
    you will need to set $Conf{CgiAdminUsers} so you have
    administration privileges in the CGI interface.

  - Edit the list of hosts to backup in /opt/etc/backuppc/hosts.

  - Read the documentation in /opt/local/backuppc/doc/BackupPC.html.
    Please pay special attention to the security section.

  - Verify that the CGI script BackupPC_Admin runs correctly.  You might
    need to change the permissions or group ownership of BackupPC_Admin.
    If this is an upgrade and you are using mod_perl, you will need
    to restart Apache.  Otherwise it will have stale code.

  - BackupPC should be ready to start.  Don't forget to run it
    as user backuppc!  The installation also contains an
    init.d/backuppc script that can be copied to /etc/init.d
    so that BackupPC can auto-start on boot.  This will also enable
    administrative users to start the server from the CGI interface.
    See init.d/README.

Enjoy!

Install BackupPC clients

Choices:

rsyncd
Can do a full backup w/o giving access to root. access can be restricted to read-only so that backup server cannot do damage to client if compromised. Requires setting up a server and install xinetd. Authentication is weak though, but not much a problem (files are already available on the backup server anyway). Quite simple to configure. I don't like xinetd/inetd though.
ssh+rsync
Login on client as user 'backuppc'. SSH private key on backuppc is password-less, but similar to storing a secret password in some file on the backup server. Root access on the client given via sudo, and restricted to run "rsync --server --sender *", such that to enforce read-only access. All traffic goes via ssh, and hence is encrypted. Strong authentication. A bit more complex to configure, but no xinetd, and no daemon.
See http://www.systemajik.com/blog/setting-up-backuppc-on-ubuntu/ for more information.

ssh+rsync is more difficult to setup; also on the NAS, the backuppc does not have dedicated home directory. So we can't easily store .ssh/id_rsa.pub and .ssh/known_hosts file. Also, on Windows client, it seems the default solution is to use rsyncd. Also, I don't really need link encryption.

We choose rsyncd:

Install log: 

vi /etc/default/rsync
sudo apt-get install xinetd
vi /etc/xinetd.d/rsync
#    service rsync
#    {
#        disable = no
#        socket_type = stream
#        wait = no
#        user = root
#        server = /usr/bin/rsync
#        server_args = --daemon
#        log_on_failure += USERID
#        flags = IPv6
#    }
sudo vi /etc/rsyncd.conf
#    max connections = 2
#    log file = /var/log/rsync.log
#    timeout = 6000
#
#    [share]
#    comment = Public Share
#    path = /home/share
#    read only = yes
#    list = yes
#    uid = nobody
#    gid = nogroup
#    auth users = backuppc
#    secrets file = /etc/rsyncd.secrets

# (Note: default timeout 300 is not enough for our NAS - we get child exited prematurely errors)

sudo vi /etc/rsyncd.secrets
# user:password
sudo chmod 600 /etc/rsyncd.secrets
sudo /etc/init.d/xinetd restart

# Testing
sudo rsync backuppc@hostname::share

Benchmarks

0 	 full 	 3565 	 73.2 	 0.68 	 884 	 4.5 	 3425 	 68.8 
1 	 incr 	 270 	 201.8 	 1.25 	 29 	 0.0 	 480 	 201.8

0 	 full 	 3 	 4.5 	 2.9 	 35.4% 	 68.8 	 56.8 	 17.5% 
1 	 incr 	 3 	 0.0 	 0.0 	 -6.4% 	 201.8 	 199.1 	 1.3%

Performance not very good. Let's disable compression and do again. I get 1.25MB/s for first full backup. When pinging nxl67170ux, I get my wlan0 address! Let's disable WIFI and start again...

Troubleshooting

Broken pipe

Typical errors: 

rsync_bpc: writefd_unbuffered failed to write 426 bytes to message fd [receiver]: Broken pipe (32)
Possible causes and solutions
  • Happens more frequently with big files, but some small files fail too. Not always the same file
  • Timeout issue
  • Firewall
  • Lots of packet loss / reject. The following iptable route might help [1]:
iptables -I {line} -p tcp --tcp-flags SYN,RST,ACK,FIN ACK -j ACCEPT

Issues on Lacie-Cloud

Broken pipe, etc

I get failed backup on the lacie-cloud server; I log my findings / tests here.

The current rsync command line is:

Notes
  • Still use the old parameter --log-format, which has been deprecated and renamed to --out-format in newer rsync version.
Out-of-memory
  • Look at dmesg output, and see if there was an Out of memory error:
dmesg|grep -iC 3 "out of memory"
grep -iC 3 "out of memory" /var/log/messages     # To get real timestamps

If so, free some memory. Possibly remove hard-link detection which consumes memory [2].

Checking the client log on lacie-cloudbox (using BackupPC_zcat to decompress), we actually observe that the log is truncated much before the rsyncd log. So it seems the client broke but did not exit. So adding param --timeout to rsync client might not help here.

bpc_fileOpen: can't open pool file

The problem is not solved at next backup. A similar problem is reported by another user on backuppc-users mailing list [3].

Stale transfer

Some troubleshooting commands [4]: 

strace -p $PID
lsof -f | grep rsync                          # and the following to confirm)

FIXED - rsync_bpc keep transfering same file on ntfs-3g mount

SOLUTION: Remove options --links and --hard-links when backing up ntfs-3g partitions !!!


Setup
  • /c is a ntfs-3g mount. Content of /etc/fstab:
UUID=445E1B975E1B813A 				/c              ntfs    ro,defaults,nls=utf8,umask=007,gid=46 0       0
  • To test this, add to /etc/rsyncd.conf:
+[test1]
+comment = Test share 1
+path = /c/Boot
  • In a separate window, monitor the rsyncd log file:
tail -f /var/log/rsync.log
  • Create rsync password file:
sudo -v; sudo sed -r 's/^.*://' /etc/rsyncd.secrets | sudo tee /tmp/rsyncd.secrets > /dev/null; sudo chmod 600 /tmp/rsyncd.secrets
Test case one - PASS - rsync + ntfs-3g
  • Initialize:
sudo rm -rf /tmp/rsynctest; sudo mkdir /tmp/rsynctest
  • Repeat the following step, and observe that files are only txfed the first time:
sudo rsync --super --recursive --protect-args --numeric-ids --perms --owner --group -D --times \
--links --hard-links --delete --partial --log-format='log: %o %i %B %8U,%8G %9l %f%L' --stats \
--modify-window=5 --one-file-system --password-file=/tmp/rsyncd.secrets \
--checksum backuppc@griffin::test1 /tmp/rsynctest
Test case two - FAIL - rsync_bpc + ntfs-3g
  • Initialize:
sudo rm -rf /tmp/rsynctest; sudo mkdir -p /tmp/rsynctest/cpool; i=0
  • Repeat the following step, and observe that files are always txfed:
cd /tmp/rsynctest; i=$((i+1)); echo backup $i; sudo cp -ar pc/griffin/$((i-1)) pc/griffin/$i; \
sudo rsync_bpc --bpc-top-dir /tmp/rsynctest --bpc-host-name griffin --bpc-share-name test1 --bpc-bkup-num $i \
--bpc-bkup-comp 3 --bpc-bkup-prevnum $((i-1)) --bpc-bkup-prevcomp 3 --bpc-log-level 3  --super --recursive \
--protect-args --numeric-ids --perms --owner --group -D --times --links --hard-links --delete --partial \
--log-format='log: %o %i %B %8U,%8G %9l %f%L' --stats --modify-window=5 --one-file-system \
--password-file=/tmp/rsyncd.secrets backuppc@griffin::test1 /

Increase --bpc-log-level (say set it to 9) to get more debug output.

Test case three - PASS - rsync_bpc + ntfs_3g fixed
  • Edit /etc/rsyncd.conf such that share test1 no longer points to an ntfs-3g mount point. For instance:
 [test1]
 comment = Test share 1
-path = /c/Boot
+path = /boot
  • Run step above, and observe that files are only txfed once.
  • If running other cases, reset share to ntfs-3g:
 [test1]
 comment = Test share 1
-path = /boot
+path = /c/Boot
Test case fourth - rsync_bpc + ntfs-3g that works
  • Initialize:
sudo rm -rf /tmp/rsynctest; sudo mkdir -p /tmp/rsynctest/cpool; i=0
  • Repeat the following step, and observe that files are only txfed the first time when removing parameters --links --hard-links:
cd /tmp/rsynctest; i=$((i+1)); echo backup $i; sudo cp -ar pc/griffin/$((i-1)) pc/griffin/$i; \
sudo rsync_bpc --bpc-top-dir /tmp/rsynctest --bpc-host-name griffin --bpc-share-name test1 --bpc-bkup-num $i \
--bpc-bkup-comp 3 --bpc-bkup-prevnum $((i-1)) --bpc-bkup-prevcomp 3 --bpc-log-level 3  --super --recursive \
--protect-args --numeric-ids --perms --owner --group -D --times --delete --partial \
--log-format='log: %o %i %B %8U,%8G %9l %f%L' --stats --modify-window=5 --one-file-system \
--password-file=/tmp/rsyncd.secrets backuppc@griffin::test1 /
