Removing old FileStorage backups from repozo
Hi I'm using the repozo.py script to back up some large FileStorages, as outlined in: http://www.zope.org/Wikis/ZODB/FileStorageBackup I need to clear out old backups regularly, as there are several storages which are packed every night, and so there are lots of ~2G backups files around for every day. Can I just go in and delete files older than X days from the backup directory, or will this upset repozo, which apparently keeps info about its backup files in the .dat file? Thanks, Felix.

You can safely delete all files older than your last *full backup*. jens

Are you doing full backups every time? It's surprising if you get 2GB of new files every day when doing incremental backups.

As Jens said, it should be safe to delete anything older than the most recent full backup. Please try the patch in this collector issue: http://www.zope.org/Collectors/Zope/1501 and add a comment there about whether you're happy with it? That adds a new option to repozo to automate deleting old files. The chances of that patch going in would increase if someone reports they use it and are happy with it.

I used to do it weekly, but some of the storages grow to over 4G, so I've been doing it nightly, which keeps it around 1.8G - 2.5G during the course of the day.

OK, I'll give it a try. Felix.

What would be most useful is the ability to specify the number of backup files *kept*. -- Eddie Butcher Road Tech Computer Systems Ltd http://www.roadrunner.uk.com 01923 338033
