VSS support for backup and Archive bit

Dear all,
just a clarification, please.

When I do backups on W2003 servers, I always enable the VSS support, in order to catch the open files too. But I also see in the backup logs: "Clearing archive flags is not applicable with Volume Shadow Copy backup.".
So, the question is: how can the incremental backups which run later on, distinguish what to backup respect to the previous Full? Does DP looks into his catalogue for each file?

Thanks, Alessandro

Hi Alessandro,

I don't actually know the answer but it makes sense to me.

Unix backups will work in the same way because Unix doesn't have the archive bit.

There are actually a number of advantages to working this way. Say an incremental backup gets deleted and that had your changed file on it. The next incremental will not find the changed version and will back it up again.

Re: VSS support for backup and Archive bit

Just a comment: Rhetorical BTW

So because DP is designed around backups on UNIX that you put the same file handling rules in place for all Windows O/S'?????

No wonder we Windows System Admins who are forced to use DP, have to "wade" through a bunch of "warning" messages that are actually meant for UNIX users on DP???!!
