Resolution
When backing up Enterprise Vault Index or Vault Store resources, Backup Exec will place them in backup mode. Once each backup set is complete, the resource is taken out of backup mode. In some instances the backup job will fail or hang when the Backup Exec is trying to toggle backup mode. The Enterprise Vault trace utility, DTrace can be used to confirm that the backup mode command has been received and properly implemented. Use DTrace as follows:
On the Enterprise Vault server, from a command prompt, first change to the Enterprise Vault directory, then type dtrace and hit enter
At the DT> prompt that appears type:
set storagemanagement verbose
and hit enter
Then type
log c:\dtrace.log
and hit enter
Leave the dtrace window open and minimize it. When testing is complete type quit to stop dtrace logging.
Run the backup of the EV Index or Vault Store resources where a problem is suspected. Once testing is complete, open the dtrace.log document and look for the following lines to see that Enterprise Vault as successfully received and implemented backup mode. Below are the lines to expect when the vault store is successfully put into backup mode:

If debugging is also enabled on the EV server for beremote.exe, the following will be seen for this operation:
BEREMOTE: [06/05/15 13:58:04] [2720] [ndmp\ndmpsrvr] - ndmpdPutEVInBackupMode: Inside ndmpdPutEVInBackupMode()
