Matthew,
Is it possible the scheduled backup is attempting to perform multiple 
concurrent database backups?  If so, the databases must all be on separate 
volumes, in order for VSS to work correctly.
Just throwing thoughts out.

Matthew, it looks like this may be a scheduling hiccup between TDP and VSS. The 
error indicates VSS is not done with what it was doing and TDP asked it to do 
another VSS operation. Interestingly enough, there is a hotfix available for 
the very VSS error you get on Server 2012 and VM backups.

Subject: [ADSM-L] TDP for Exchange Failures

Hello All,



I've been getting numerous failures with our Exchange Backups that are being 
executed via a scheduled command as shown below.  Server Version: 6, Release 1, 
Level 4.5, TSM Client Version: 6.2.3.0, TDP Client Version: 6.1.3.0 all running 
on Windows 2008 R2 and Exchange 2010 SP2 Rollup 3 and we are running from a 
replica mailbox server with the Proxynode option set for this Mailbox server 
with the passive copies of the databases.  We have had no problems for years 
and nothing has changed besides growth but lately we have been getting tons of 
failures such as:



Event Logs:

Failure Executing Schedule EXCHANGE2010_4, RC=450.

Failure Executing Schedule EXCHANGE2010_4, RC=418.

VSS processing encountered error 'VSS_E_SNAPSHOT_SET_IN_PROGRESS' in the Volume 
Shadow Copy API 'StartSnapshotSet'.



DSM Logs:

ACN0519E The VSS operation failed with rc = 450.

ANS1017E (RC-50)  Session rejected: TCP/IP connection failure

ACN5060E A Tivoli Storage Manager API error has occurred.



Again, The majority of our DB's backup but we get 3-6 failures a day and it's 
not the same ones every day.  One that was successful yesterday could fail 
tonight.  It's just very odd
