As part of my backup strategy for my SBS 2003 server, I created three scheduled tasks to backup the C drive with Exchange to a NAS. (The shared files are on different partitions and are backed up separately). The NAS drive is volume X and it has three folders and backup files as follows:
I set it up this way to mimic a three-day tape rotation scheme. Each task is scheduled to run around 1 am every third day. It was designed to go to it's designated folder, delete the backup file that is currently there, and run a new backup. This way, I should have full backups of my server's C drive for three days. Every few weeks I needed to go to the recycle bin of the NAS and permanently delete all of the old .bkf files. This system was working great for about 5 months. A few weeks ago I noticed that all three of the scheduled tasks stopped working. Checking Event Log I found the following error on a daily basis right around 1:00 am:
Event Type: Error
Event Source: NTBackup
Event Category: None
Event ID: 8017
Time: 1:22:16 AM
NTBackup error: 'The operation failed. Consult the Backup Report for more details.'
Checking the backup log I found what appears to be a simple explanation to the problem:
The operation was not performed because the specified media cannot be found.
I cannot understand why all of a sudden the scheduled tasks cannot find the media. The server is able to ping the NAS device and the drive X shows up under Explorer from the SBS server. What would cause backup to be unable to find the media? I should point out I have another scheduled task that runs the same backup every day to an external RDX drive. That task simply writes over the files daily and it continues to work fine. Over the past few months I have rebooted the server several times to install MS Updates. Those have been the only changes.
Here is the syntax related to one of the jobs called "SBS-Synology-1.job"
up.exe backup "@C:\Documents and Settings\Administrator\Loc
al Settings\Application Data\Microsoft\Windows NT\NTBackup\data\SBS-Synol
/n "SBS-Backup-NAS-1.bkf created 1/21/2014 at 10:58 AM" /d "Set created 1/21/2014 at 10:58 AM" /v:yes /r:no /rs:no /hc:off /m normal /j "SBS-Synology-1" /l:s /f "X:\SBS-Backup-NAS-1\SBS-B
For months, when this worked the file X:\SBS-Backup-NAS-1\SBS-Ba
ogy-1.bkf would be replaced every third day. I realize I could re-create these tasks and hopefully solve the problem. I would prefer to understand why these working tasks all of a sudden stopped working.
Thanks in advance for your help!!
