Windows Server - Backup problems

Asked By Don Tagliatelli on 30-Jan-09 06:02 AM
Hi,

I'm getting a lot of failed backups and I don't know where to start because
every error message seems different.

Last 10 days I had 6 failures.

It's a SBS 2003, with Seagate tape drive and HP tapes (DAT72)

These are some of the errors in the backup log:

The requested media failed to mount. The operation was aborted.
The operation was ended.
-------
Error: The device reported an error on a request to write data to media.
Error reported: Bad data.
There may be a hardware or media problem.
-------
Error: D: is not a valid drive, or you do not have access.
Error: The device reported an error on a request to rewind the tape.
Error reported: Hardware failure.
There may be a hardware or media problem.
Please check the system event log for relevant failures.
Error: PYRAMID-SERVER\Microsoft Information Store\First Storage Group is not
a valid drive, or you do not have access.
Error: The device reported an error on a request to rewind the tape.
Error reported: Hardware failure.
There may be a hardware or media problem.
Please check the system event log for relevant failures.


I also noticed the cleaning light is on every day, normally it should be +/-
once a week.
I tried cleaning it 5 times in a row, but the backup still fails...
I also tried XTalk, a tool to test a tape drive but it gave no errors.


Ten days ago we moved our server to another location. We did it very
carefully, could this break the tape drive?
Also, ten days ago we switched our tapes. Maybe the HP tapes are crap?
Anyone uses those tapes?

I'm going to try another brand of tape tonight, to see if that works. But it
looks more to me as a hardware problem...

Any suggestions?

Thanks,
Vincent

Hi Don:

This problem has too many contributing possibilites to give a one off
answer.  Typically problems with tape drives and SBS backup are resoved by
resetting the Removable Storage Service  and or the Removable Storage Media
(RSM) and or the VSS writers.  But the cleaning light is either a red
herring or a big signal that not all is well.  I would start by contacting
the drive mfg for a dianosis on the drive, and by trying the tapes that
worked prior to the advent of the new tapes.  I would not expect HP branded
tapes to be "crap", but it is possible that you somehow got a bad batch.

I have a customer who also has to clean their drive every day, but theirs is
a dusty enviornment.  Assuming that when you moved the server it did not
leave a nice clean office and go into a dust filled shop, just moving it
should not have caused this.  One possibility is that the data cable is not
well seated at one or more connectors, or, if SCSI the terminator is loose.

You can, and probably should, try a manual backup with NTBackup or whatever
third party program you use.

Here is a list of common solutions to backup issues:

For RSM /RSS possibilities here is a starter:

In addition, there is a latest version of VSS:
833167 A Volume Shadow Copy Service (VSS) update package is available for
Windows Server 2003

I suggest you install the hotfix for the VSS to check the status since the
hotfix has fixed many known issue.

NOTE: hotfixes are generally available for specific issues in the Product.
Please keep in mind that they are not fully regression tested and should be
applied only to systems experiencing the specific problem. For this reason,
the first step would be to verify if you are indeed running into the
problem addressed in a specific hotfix. The individual sending of hotfixes
must be tracked by Microsoft for reasons such as: you may run into problems
after installing the fix, when future updates to the hotfix occur we want
to be able to notify you. For these reasons and others, many hotfixes are
only available to customers if they call into the appropriate Microsoft
Support phone line, and receive direct help and advice from a Microsoft
support professional. We are not equipped to send out and track hotfixes
here in the Newsgroups forum.

If you prefer, you could contact Microsoft Product Customer Services
directly to obtain the fix. For a complete list of Microsoft Product
