dansimau / reduce-backups.sh
Created January 20, 2012 09:57
Prunes Squiz CMS backups to the last X number of days. Will bail out if the backups have broken, to avoid deleting backups if they may be needed.
#!/bin/bash
#
# Reduces the total number of Squiz CMS backups to the last X days', whilst
# also ensuring at least X number of backups always exist.
#
# In other words, we want only the last X number of days' backups unless the
# backups have failed, in which case we'd prefer to keep the old ones until
# the backup is running again.
