I had almost exactly this problem, only my situation was even
simpler. I was doing a vanilla directory backup with 2.4.0 on Windows
Server 2003 and every _other_ backup would result in the following:
07-Jul 19:04 fs-fd JobId 5: Generate VSS snapshots. Driver="VSS Win
2003", Drive(s)="D"
07-Jul 19:04 fs-fd JobId 5: Could not stat d:/Shares: ERR=Access
is denied.
This would result in the same "Backup OK -- with warnings" as your
output below. It would fail reliably 50% of the time. I did a naive
test of VSS by running ntbackup several times and it succeeded every
time, so I just disabled VSS with "Enable VSS = no" in the FileSet.
All my backup jobs since have been successful.
Since you're backing up dumped files, I don't imagine you need VSS
anyway.
