8.4 Differential backup and data synchronization

Differential backup and data synchronization can be implemented with several methods:

  • rcs: backup and history, text-only

  • rdiff-backup: backup and history. symlink OK.

  • pdumpfs: backup and history within a filesystem. symlink OK

  • rsync: 1-way synchronization

  • unison: 2-way synchronization

  • arch: multi-way synchronization with server backup and history, no such thing as a "working directory".

  • subversion: multi-way synchronization with server backup and history, Apache.

Combination of one of these with the archiving method described in Copy and archive a whole subdirectory, Section 8.3 and the automated regular job described in Schedule activity (cron, at), Section 8.6.27 will make a nice backup system.

I will explain three easy-to-use utilities.
