It appears as if there have been changes to the VSS backup portion of NW 
8. In 7.6.2, there used to be 5 VSS savesets:
(this is backing up a Win 2008 R2 server)

VSS SYSTEM FILESET:
VSS SERVICES:
VSS BOOT:
VSS USER DATA:
VSS OTHER:

Now with 8.0.1.5, it appears the last 2 (VSS BOOT:, VSS USER DATA:) no 
longer exist (or don't get backed up, I'm not sure which). If I specify 
all 5, backups fail with the last 2 as "No such file or directory".

So this is an expected change, I take it? I don't seem to find any 
reference to such a change in the NW 8 SP 1 Administration Guide.
