Hello,

We have a Windows 2000 Server and the scheduled backups are not running. It says that the specified Media cannot be found. However, if we do a manual backup, it works fine. Any ideas?

Hi

What program are you using to schedule the back-ups? Also, are you backing up to tape? If you are backing up to tape and you are running a backup program using GFS then you need to either use a blank tape or insert the tape specified. We use ArcServe, and have to use a particular tape depending on wether we are doing a daily, weekly or monthly backup.

Hope this helps

We are using NT Backup. We have a mapped drive on the 2000 server that points to our backup server. There is no problems with the mapping, as the backup works if we do it manually.

Scheduled Backups Fail on Standalone Tape Drives After Changing Media
Article ID : 267574
Last Review : November 14, 2003
Revision : 1.0
SYMPTOMS
When you schedule a Windows 2000 unattended backup by using a standalone tape drive (library), the first backup job completes successfully. However, after you change the media, the next scheduled backup job does not back up the desired folder and files. Also, you may receive one of the following error messages in the backup report log file:
The operation was not performed because no unused media was available.
-or-
Operation was not performed, because the specified media cannot be found.
CAUSE
This problem can occur if Removable Storage Manager (RSM) is not notified when the media on the standalone tape drive (library) is manually changed. Removable Storage Manager does not poll standalone libraries looking for media changes, and it is the responsibility of the RSM aware program to request that RSM detects if the media changed on standalone libraries. When this problem occurs, RSM updates the tape drives media contents in the RSM database. Usually, when Windows backup is running interactively, it requests that RSM polls the tape drive(s) periodically looking for media changes. When backup is not running, there is no mechanism to request RSM to detect media changes. Backup is unable to issue a mount of the new tape because RSM is not aware that the new tape exists, resulting in a backup job failure.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
