Exchange 2013 VSS writers missing

i'm in the middle of migration from  Ex2007 to ex2013.
Migrated test account and created couple of migration jobs.
Everything seems ok but on Ex2013 Exchange VSS writers keeps vanishing.
I'm using BackupExec and will not finish migration until i sort the backup, i have found out that after restarting Exchange Replication service i'm having writers back for a while but then i came back another morning with another failed job because exchange writer went missing.

anyone had the same experience?

Windows Server 2012 R2
Exchange 2013 CU20

have seen this issue multiple time, restarting the information restore service fixed the issue for me, if you have DAG setup then move the active DB on a different Node and then restart the service.

not a DAG, simple one server configuration

probably then check for the old vss shadows and try cleaning them.

Yes, Exchange VSS Writer give issues.

Please make sure "Disable Exchange Writer" registry key to a value of 0 at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem

Let us know What version of BackupExec you are using?

Also verify the below registry value as well
Check that the registry key is enabled on the Exchange server   HKEY_LOCAL_MACHINE\Software\Microsoft\ExchangeServer\v14\Replay\Parameters\EnableVSSWriter = 1
and then restart the Microsoft Exchange Replication Service on the Exchange server
