Windows Server 2003 Backup.

[David Parkes]

We are running Windows Server 2003 on an HP Proliant ML350 G4. We are using
a Quantum DLT8000 tape backup device. The problem we are having is that the
backup never completes successfully. We are trying to back up around 52GB of
data split across three hard disks. The Hardware Compression is switched on
on the tape drive and our backup command has the /hcn switch. The tape is
a 40/80 GB tape. Service Pack 2 for Windows Server 2003. I have also added
the /UP switch to the backup command.
The following entry is dropped in the Application Log:
Event Type: Error
Event Source: NTBackup
Event Category: None
Event ID: 8001
Date: 04/07/2008
Time: 12:47:05
User: N/A
Computer: VNI3
Description:
End Backup of 'E:' 'Warnings or errors were encountered.'

Verify: On
Mode: Append
Type: Normal

Consult the backup report for more details.

We are using tapes which have been marked as free.

The backup log is trucated mid entry and there are no entries in the log
file staing what has happened.

Any ideas?

Re: Windows Server 2003 Backup.

Sounds like you've probably ran out of space on the tapes. Although they are
40gb uncompressed tapes you will probably only get about 50gb or so on them
depending on the type of files your backing up.

Try removing something out of the backup which is a gig or so in size and
re-run it. Unfortunately ntbackup isn't great for reporting specific erros.

First off, don't append. Have it use the entire tape.

The *BEST* you can expect on a 40/80 GB tape is about 60GB. You're never
going to get much better than 1.5 to 1 compression. It looks like you
are running out of space.

You need to exclude something. There has to be several GB that really
aren;t necessary if you have to restore....
