Hi there,
We're running Zope on an NT server here and the backup system (Arcserve) apparently gives an error when it tries to backup Zope's 'var' directory.
What is the error?
I'm not sure yet, but Ronald Offerman's post on arcserve is quite enlightening:
BTW, arcserve HATES doing backups of open files even when files are opened > O_RDONLY.
I suspect it's this then.
I would like to have this succeed (and end up with a non corrupted database, of course :), so here are some questions:
* is this perhaps fixed by Zope 1.10?
Without knowing the error, it's hard to say. :)
Well, one never knows. :) [snip]
* Is copying a database while Zope is running a good strategy? (probably not)
In 1.10 and later, yes. If the database is being written while the file is being copied, then the Zope may discard the last transaction when reading the copy, if the last record is incomplete. Zope 1.9 reported a corrupted database if the last record was incomplete.
Okay, I'll just make a copy then, and try to get arcserve to do a backup of that. As arcserve apparently has good scripting capabilities this shouldn't be a problem. Thanks! Martijn
