[Zope] Removing old FileStorage backups from repozo

[Felix Ulrich-Oltean]

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.
