How?

List of backup software.

Attic

Maybe best to consider its fork instead: BorgBackup.

BackupPC

See BackupPC.

BorgBackup

See Borg on GitHub.

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.

Obnam

Tutorial, manual.
Reviews
Pros
  • Can be tuned to make it much faster (up to 10x, with extra memory though) [1]
Cons
  • Slow with small files [2]
  • Very slow, in particular large backup [3], [4].

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.

What?

A backup checklist.

On Linux

  • /home directory
  • /etc directory

In addition:

  • Get a copy of crontab (although they are in /var. For each user:
crontab -l

sudo su -
mysqldump -u root -p --all-databases > mysql-$hostname.dump
