Backup
Summary
- Borg
- Fastest.
- Does not necessarily require server setup. Access repo via Samba.
- Would be more secure though via server access.
- Multi client is still experimental.
- Bup
- Fast but initial copy slower than Borg, incremental faster than Borg.
- Faster if access repo via server.
- Cannot purge easily.
- UrBackup
- Very nice front-end (web-based). Nicer than BackupPC.
- Fast, but slower than Borg/Bup.
- Ridiculously high number of files in repo, which makes it difficult to manage / stat.
- BackupPC
- Nice front-end.
- Require server access.
- Ridiculously high number of files in repo, which makes it difficult to manage / stat.
Online backup
rsync.net
- Use Borg as backup solution.
- Praised by several users.
- Start plan at $18/yr for 100GB storage (ie. 1.5 ct/GB/month).
CrashPlan
CrashPlan is one of the online backup solution recommended by LifeHacker.
- Family plan $150.00 / year for 2 to 10 PC.
- Available for Windows, Mac, Linux.
- Unlimited storage
Backblaze
An alternative to Crashplan. See Backblaze B2 for backup with duplicity.
Tarsnap
Tarsnap is a deduplicated, encrypted online backup service for the truly paranoid. It works on UNIX-like operating systems, and has backup plans starting from $0.25/GB-month.
Advised by MIT Hacker-tools.
Local backup software
List of backup software.
Attic
Maybe best to consider its fork instead: BorgBackup.
BackupPC
See BackupPC.
BorgBackup
See BorgBackup.
Borg is actually a fork of Attic.
- With interesting comments, config... Also mention cloud solution rsync.net with support for Borg/Attic and ZFS.
Bup
See Bup.
Burp
See Burp.
- First impressions
- Protocol 1 appears fast, but doesn't do cross-client deduplication. Protocol 2 is still experimental, and is very slow.
Obnam
- Reviews
- Pros
- Can be tuned to make it much faster (up to 10x, with extra memory though) [1]
- Cons
SimpleSnap
SimpleSnap is a tool to backup ZFS snapshots easily.
Pros:
- Very fast snapshot (25s).
Cons
- Requires ZFS
- Not cross-machine deduplication.
Speed seems very interesting. But how setup ZFS? Maybe some hints in this benchmark from same author.
UrBackup
See UrBackup.
Looks promising. Server-centric like BackupPC.
- Pros
- Consistent backup using snapshots!
- Snapshots created with dattobd or LVM snapshot on Linux, and VSS (Volume Shadow Copy Service) on Windows.
- Cons
- Does not support storing repo on Samba FS (because create symlinks). But this can be fixed by using NFS.
Other
- Amanda
- Bacula
- Backupninja
- brackup
- Duplicity
- rdiff-backup (review)
- rsync (Optimal remote backups with rsync over Samba)
- ZBackup
- S3QL
For Windows:
- Bvckup2, claimed to be fast, efficient, simple.
Tools and features
- dattobd
- Datto Block Driver is a kernel module for taking block-level snapshots and incremental backups of Linux block devices.
- LVM snapshots
- Taking a Backup Using Snapshots - LVM How-To.
- Other
- Windows Volume Shadow Copy Service (VSS)
How well?
List of backup reviews:
- Review Bacula, Amanda, Backupninja, Backuppc, and UrBackup. Also cite Rsnapshot, rdiff-backup, Burp, Duplicity, SafeKeep, DREBS.
- Attic wins hands down on big data set for backup, and in all cases for restore (much much faster).
- Both looks similar. Attic a bit faster.
- Compare features of many different backup software. See also update from User:Level323.
- Issue tracker on Borg to compare it with alternatives.
- Mainly compare Obnam and Attic/Borg.
- Compare ext4, S3QL, SDFS, zfs-fuse (fastest).
- Very long list of backup software with Pros and Cons.
What?
A backup checklist.
On Linux
- /home directory
- /etc directory
- /usr/local directory
- /root directory
- /var directory
In addition:
- Get a copy of crontab (although they are in /var. For each user:
crontab -l
- Get list of installed packages:
dpkg -l
dpkg --get-selections
- Copy all mysql database (although they are in /var and /etc.
sudo su -
mysqldump -u root -p --all-databases > mysql-$HOSTNAME.dump
