We use EMC NetWorker for our enterprise backup solution. Since we migrated our primary file server from a NetApp filer to a native Windows server, we’ve been having a recurring problem with all the Shadow Copies for a volume getting deleted. There are strong indications that the problem is related to the NetWorker backups.
As we have been working on this issue with EMC (since the first week in January!), I wrote a script to tell me two things each morning; how many snapshots exist for each volume, and what VSS errors were logged, if any.
I thought someone might find it useful, so I’ve posted it as a separate page (the script doesn’t fit nicely in the column on the blog).
