.... but OTOH, it can take a looooong time to pack. I have a weekly cron job that packs my ~3 GB DirectoryStorages and they frequently take well over an hour each. Full backups take roughly an hour too. Incremental backups are pretty quick, e.g. last night's 91 M backup took 1 minute. I'm a big fan of DirectoryStorage, but in terms of raw speed it's slower in some ways. Packing is memory-friendly but slow. (If Also you mention issues with incremental backup of Data.fs. Did you ever try repozo.py? Just mentioning it for completeness. > 5) POSKeyErrors. We where getting quite a few of those, and that scared > me. with DirStor, I do not see them as much as before. I don't see them ever :-) That was the big motivator for me. -- Paul Winkler http://www.slinkp.com _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
