Event viewer on exchange server shows following event IDs
Event ID : 9840
Raw Event ID : 9840
Record Nr. : 50522

Message : An attempt to prepare the storage group 'sg2' for backup failed because the storage group is already in the process of being backed up. The error code is -2403. (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.)

Description: An attempt to prepare the storage group 'sg3' for backup failed because the storage group is already in the process of being backed up. The error code is 1293.

When you try to perform a VSS backup of a mailbox database or of a public folder database in Microsoft Exchange Server 2003, the backup operation fails. Additionally, the following event is logged in the event log:
Event Type: Error
Event Source: MSExchangeIS
Event Category: Exchange VSS Writer
Event ID: 9607
Description: Error code 0x50d when preparing for backup.
Data: 0000: 42 61 63 6b 75 70 20 69 Backup i 0008: 6e 20 70 72 6f 67 72 65 n progre 0010: 73 73 2e 00 ss..
This problem may occur if the following conditions are true:
1. VSS uses the Microsoft Jet database engine to freeze or thaw a snapshot backup.
2. The Jet database engine encounters an error.
3. The Jet database engine silently frees all storage groups from the snapshot session when the error occurs.
This is Microsoft exchange related issue and solution is present on following Microsoft technical article :-
Event ID 9840 or 9607 is logged when a VSS backup operation fails in Exchange 2007, Exchange 2010 or in Exchange 2003

Restart Microsoft Exchange Replication service on Exchange server and retry the backup for High Availability Server (Exchange 2007 or later).
Method 1: Dismount all databases in the storage group
Use this method if the event ID 9840 that was logged on the Exchange 2007 server contained error code 2403.
To dismount all databases in the storage group, follow these steps:
1. Click Start, point to All Programs, point to Exchange Server 2007, and then click Exchange Management Console.
2. Expand Server Configuration, and then expand the storage group that is listed in the event ID 9840 message that was logged on the Exchange 2007 server.
3. Right-click each database in that storage group, and then click Dismount Database.
4. Click Yes to confirm the operation.
5. After the dismount operation is complete, right-click the database again, and then click Mount Database.
6. Try to perform the backup operation that resulted in event ID 9840.
If this method does not resolve the problem, try method 2.
Method 2: Restart the Microsoft Exchange Information Store service
Use this method if the event ID 9840 that was logged on the Exchange 2007 server contained error code 1293. Use this method if Event ID 9607 was logged on Exchange 2003. Additionally, use this method if method 1 did not resolve the problem.
To restart the Microsoft Exchange Information Store service, follow these steps:
1. Click Start, point to All Programs, point to Administrative Tools, and then click Services.
2. Right-click Microsoft Exchange Information Store, and then click Restart.
3. Try to perform the backup operation that resulted in event ID 9840.
