Backup Exec Completes successfully but no files found on the tape

I have a Dell Poweredge 2800 server running Windows 2003 server, an external HP storageworks Ultrium 460 tape drive connected via an Adaptec 29160 SCSI card. I am using Veritas Backup Exec for windows servers version 9.1 rev 4691 and everything looked fine.

BE runs on schedule and the backups complete successfully. I checked on yesterday and cd not find any data on the tape. I checked a few more and realised that al the tapes used over the last 3 weeks since the installation are blank. The BE logs show successful backup and verification, the BE database assumes successful completion, except when it comes to restore the data - it asks for the right tape but ther files do not exists.

I obviously need to solve this before it becomes and issue - any ideas?

When you go to the Restore tab, are the backup sessions available for selection?

If not, have you tried to run a Catalog on the tape?

I'm wondering if you have an issue with the BE database (easily fixed) or something far more sinister....

The BE database seesm to be intact - the separate sessionsare available on the restore selection, but fails when it actually looks at the tape for the files - they do not exist
when I inventory or catalogue the tapes it display 0 files and 0 bytes

Looking back at the logs of the job
Backup Set Summary
Backed up 88309 files in 8700 directories.
Processed 186,074,013,944 bytes in  1 hour,  56 minutes, and  48 seconds.
Throughput rate: 1519 MB/min is this is a little quick for the Adaptec 29160 card
 
I installed the HP storageworks tools softwa to check out the installation . when it ran the server blue screened - scary!

That's a red herring. From memory the cause of the BSOD when you run tape tools is either the SCSI driver or RAID controller driver - IIRC you have to downgrade the PERC driver. As an alternative you can burn a bootable tape tools CD that allows you to run the tests.

>Throughput rate: 1519 MB/min is this is a little quick for the Adaptec 29160 card
Perhaps a little on the high side. I'd expect typical rates of around 1000-1200MB/min so it isn't outrageously high...

If you stop all the BE services, can you get a backup/restore from Windows Backup/RSM?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

when I ran windows backup it came up with an error when rewinding the tape - it says no access to drive d: which is the main datda drive. the only erros I have on teh system relate to ...
Windows cannot access the file gpt.ini for GPO CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=Enviro,DC=local. The file must be present at the location <\\Enviro.local\sysvol\Enviro.local\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini>. (Access is denied. ). Group Policy processing aborted.

which I perceive to be a separate problem which I am trying to fix.

backup report follows:-

The Storageworks software crashe because  I was running in NT miniport mode (I think) and I did have a terminator on.
I removed the terminator and the self terminating green light is active.

I found a BE fix SP2 which seems to sort the no data on tape issue, issues 68638/265701/220414
all seem to be relevant to this installation. Ran into a few problems - installed Mcafee
Protection Pilot which screwed up BE SP2 installation, had to repair the original
installation of BE and ran SP2 patch again.. and it seems to have worked

I am concerned that the Adaptec 29160 is too slow for this drive so I will swap it out soon.

The reason Windows Backup did not work but - is linked to anothe issue I have posted about group policy  (Windows cannot access the file gpt.ini for GPO CN) so we can close this session
Thanks for the tips it pointed me in the right direction - I will accept your anser so you ge the points

I'd consider a 29160 a perfect match to your drive. If you're  having backup performance issues, then I'd look at issues like file system fragmentation, RAID read caching and so on. Also, removing the terminator wll negatively affect performance.

BTW - If you're getting 1500MB/s on a regular basis, I wouldn't touch anything!
