Application log generated Error Event 9840

We are continously getting following error on exchage server

Log: Application
Type: Error
Event: 9840

Category: General
Description: An attempt to prepare the storage group 'First Storage Group' for backup failed because the storage group is already in the process of being backed up. The error code is 1293. (Note that if a backup was recently aborted, then it may take several minutes for the system to detect the aborted backup and initiate backup cleanup procedures, so this message may be generated if an attempt was made to backup a storage group before a previous backup attempt had fully terminated.)

Next thing to try is to dismount then remount your Exchange store from within the Exchange management console.

Restart the Microsoft Exchange Information Store service.

The issue is that Exchange thinks it is being backed up - some past task has failed and left the "I am being backed up" status indicator turned on.

The fix may be as simple as restarting the Microsoft Exchange Information Store service.

If that doesn't resolve it you should dismount then remount your Exchange store from within the Exchange management console.

If the issue recurs after doing both of these, then you have a backup task that is stopping during a backup - check for errors with your backup procedure. Are you getting a complete backup?

This issue will occur during backups.
what backup software you using to backup your exchange server?

Check whether there is any exchange maintainenace task running at the same time while backup is running.
Also check whether any Antivirus software is doing its checking at the same time when backup is going on.
