bzr backup with rsnapshot
rss

Banged out a quick script for backing up a directory containing a bunch of bzr depots, for use with rsnapshot:

To use:

  1. Save to /usr/local/bin/backup_bzr.py
  2. chmod u+x /usr/local/bin/backup_bzr.py
  3. Edit /etc/rsnapshot.conf and add:
    1. backup_script   /usr/local/bin/backup_bzr.py . [root dir of your bzr dirs]  localhost/bzr

Update: Just realized that maybe this isn’t as useful as I thought. ;)   Seeing as how bzr is self-contained, you could probably just rsync the entire directory and get away with it that way.  D’oh.  So used to old-style VCS that need a separate backup process than ‘cp’. ;) I’ll leave this code here in case anyone else finds it useful.
