Exchange backup is interrupted by error

There are BE 2012 and SBS server which includes Exchange 2007 in our production network and according to a schedule full backup of mail database should be done twice every week. Usually everything is ok, however, sometimes, backup process is interrupted by error and since the moment when such error occurred backup cannot be done any more because all following jobs finish with this error. Only one thing can help which is restarting Exchange service called "store.exe". After restarting backups can be done successfully again. This is information about error:

Make sure AOFO isnt enabled in the job and all the updates have been applied.  Do you have errors in Windows Event Logs?  refer here:  http://www.symantec.com/docs/TECH154496

Please check and confirm the Writer status on the Exchange server.

1. Go to command prompt

2. Use the following command:

Vssadmin List Writers

3. Hit <enter> and check if any Writers are listed with Errors/Failures

 

Best first thing to do for failed writers is a Reboot.

 

You should also check Event Viewer for any VSS related failures and confirm if any of the reported Event ID's are already listed in the following technote?

If not, please provide the Event ID and Description as seen in your case.

There are several errors in the Event Log which appear after trying to create backup in BE:

9840/2403

9814/2403

2007

9609

All solution related to your link offer to restart ethier service/servide or database and it helps, but after sometime this problem appears again. So, after rebooting I can make only several backups, after that, I have to reboot storage service again.

When I turn off AOFO problem is still kept.
