Use Rsync to Backup Zope

Created by . Last modified on 2003/08/05.

Because Zope appends new data to the end of its OODB, and because rsync only transmits the differences between two files when copying, using rsync to back up Zope is very efficient. The only time it slows down is when you pack your OODB and it has to start over. Drop this file into your Cron directory, and it will keep backups for the last seven days, using a minimum of disk copying. It can also be used efficiently over dialup lines, on a perhaps weekly basis.
