BackupPC: Difference between revisions

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.

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!

--> 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!

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!

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

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

I get for each backup the same error message:

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 /
