AT the NT file system level was the drive compressed? We had a problem that was
finally solved after two months. The issue we had was OTM on and compressed
drives and it did not back up all files. When we turned OTM off it worked like a
champ. Veritas was finally able to duplicate our problems and gave us some
recommended registry settings for otm.

Subject:  [Veritas-bu] OTM Enabled Backups Failing with 0



Greetings all.

We are have recently encountered an issue that appears to involve OTM on
Windows NT and Windows 2000 servers.  For months we have been running
backups on roughly 135 NT and 2000 servers and most of them have reported a
backup status of 0.  We were recently asked by a user to restore some lost
data.  When going into xbp and later bp to select the missing files, we
noticed that all that was backed up on the D drive was the identifier /D/
(Unix Master).  Under the identified /C/, we were able to find all of the C
drive files, but nothing on the D drive was backed up.

The backup successfully completed, though!  Veritas has been looking into
this issue for us (Case 150-081-114), but they have been unable to find
anything as of yet.

I disabled OTM and ran an incremental last night and the backup completed
successfully.  I was expecting to find that all of the files on the D drive
were backed up - the files were never backed up, so an incremental would
pick them up.  Instead, the files that were backed up were the files that
changed since the last backup.   It is as if NBU really thought that the
files were backed up.

Has anyone else seen this problem before?
