This behavior is by design; Microsoft designed VSS to exclude OST files from the shadow copy. OST files are expensive to back up and useless in a recovery. The .tmp file that you see probably is a copy that shouldn't exist in the first place - maybe antivirus software scanned the OST file and made this copy (solution: exclude OST files from antivirus scans - bad things will happen if you don't).

Subject: [Bacula-users] Backing Up Windows 7 with VSS
To: bacula-users AT lists.sourceforge DOT net;
Hello All,

I am attempting to backup a win7 64-bit machine.  It is using VSS as needed and the backup runs with no errors or warnings.  The problem I have encountered is that there is an Outlook .ost file that is about 4GB in size.  When I was looking at the files that were backed up using bconsole and restore, the filename is prefixed with a "~" and the given a ".tmp" extension.  After I mark that file and then use estimate it says 1 file to restore, 5,832,704 bytes.  Which is definitely not the right size.

I see in the messages:

JobId 143: Generate VSS snapshots. Driver="VSS Vista", Drive(s)="C"

and several:

JobId 143: VSS Writer (BackupComplete):

and that the fd and sd backed up and wrote about 85GB.

I am not sure why the oct file did not get backed up correctly?

Ideas?

Thanks,
jim
