PDMWorks Server Crash

We recently had our server crash after a power outage thatmade all the data unreadable. Our IT dept. faithfully backsup ourserver using Veritas software. However, when they try to restorethe backup, some files are unreadable. Some come through as emptyfiles. Some won't restore to the proper location but will to analternate but then loses relations with the other files (i.e. partsin assemblies).

Does PDMWorks have its own backup/restore function in order toproperly maintain relations between files that the Veritas softwareis not doing? Or, perhaps we simply have a bad backup?
