Tape Catalog with Veritas

I'm running Windows 2000 AS with a 2 terabyte ataboy in a closed network with about 10 clients.  I'm running Veritas 9 with a Dell 132 (20 tapes) LTO changer as a backup solution.

Here's what happened,
A user asked me to restore a file from a few days ago.  I lit off a restore job, redirecting the restored file to a different directory.  It got ~300 bytes into the restore and failed with an error about invalid data being read from the tape.  I repeated this a few times with the same results.  I applied the latest patch from Veritas and rebooted the box, this is where the hurting started.  When I logged back in to the server it took about 10 minutes for my profile to load, then I noticed that DNS wasn't working properly and the security log was chock full of failures of the system account trying to start various services.  I tried a few things to get the server working properly but to no avail.  My boss and I decided that since the box was never quite right to begin with I should just rebuild it.  So I removed the drive, put a new one in and reloaded Windows 2000 AS and then installed Veritas.  Things still didn't work quite right, we couldn't get it to inventory the tapes.  We changed a few settings in Veritas with the autoloader and finally got that to work.  It was at this point that I found out that cataloging the tapes takes about 20 hours per tape on an LTO2 X 20 tapes= half a month.  I think I got one tape ~90% catalogged when  I called Veritas and they said to copy the catalog files from the old drive to the new one.  Per Veritas article 256300 I copied the U01 files from \program files\veritas\nt\catalog on the old drive to \catalog on the new drive.  But now when I go to start a restore job I only see about 10 restore points from weird times (4 from 2003 and 6 from 2004) on the attaboy volume.  Called Veritas back and they basicly said "catalog your tapes", that's your only option.

So is that my only option at this point?  And if so, what's the suggested method for backing up the catalog files?

'Afraid so. However, cataloging a tape on LTO2 technology should be a damn sight faster that 20 hours!

First things first: upgrade to Backup Exec 9.1 latest build unless you have an extremely compelling reason to stay on 9.0. I usually use the Veritas drivers for the tape drives and library. If you are using an Adaptec 39160 SCSI card (and you should be to extract best performance) ,make sure the card firmware is a 3.10 and the driver is at 6.1.6300.100.

Next thing to check is that the tape library is cabled correctly. You cable should run from the SCSI card to the tape drive. You must have a terminator plugged in to the other socket.

If all is present and correct, you should be able to achieve backup throughputs in the order of 1200MB/minute and verify throughputs around 2400MB/minute. Throughputs drop when you're doing brick-level Exchange backups, or backing up zillions of littlle files (Citrix profiles, for example).

Whatever, 20 hours do do a catalogue is ridiculous. We need to fix the performance issues, then the rest will be easy!
