NTBackup Error

[Cameron Dorrough]

Hi all!! We recently started getting the following error on our nightly
Tape backups (separate server) and I have run out of things to check:

File \Projects\04000\04001\Acad\PDF\101312E3.pdf is corrupted.
This file cannot be verified.
Network disk drive has stopped responding. Backup set aborted.
Backup completed on 17/09/04 at 23:20:01.
Backed up 1945 files in 252 directories.
One corrupted file was backed up.

The Tape drive happily backs up all other machines on our network, so it
must be something to do with this server (W2kAS SP4). The problem happens
on all shared drives on this machine, so it doesn't seem to be a HDD
problem... but I've chkdsk'd and defragged all the drives anyway (no major
problems reported) and virus checked it as well (no problems reported).

The "corrupt" file is *not* corupt and can be opened fine. The file name
seems to change each time I do the backup... There are no errors in the
event logs on either machine, and the shared drive can be viewed fine in
Windows Explorer immediately following the failure.

Has anyone seen this before and know of a fix??

Thanks,
Cameron

Hi Cameron,

I'm by no means an expert in this subject matter of NTBackup, but I'll try
to assist you to the best of my ability. If you backing up file across the
network, then it sounds like you may be running in to an issue documented in
the following article.

Even though the article doesn't say it applies to Windows 2000, it may still
be related and it wouldn't hurt to try out the resolution steps mentioned in
the article because they can always be reverted back out.

Thanks heaps, Mike

Changing those reg settings doesn't seem to make a lot of difference - but I
think you might be onto something with SMB, as we have had intermittent File
Copy problems in the past with our XP clients.

It's funny - NTBackup of the dodgy server to *file* works fine!.. also the
Tape backup takes quite a while to crash out and successfully backs up a lot
of rather large files before it does...

This only started happening in the last week and no part of our set-up has
changed in that time - it's very, very strange. :-(

Anything else you can think of?
