I'm attempting to back up the information store to a backup to disk folder on my server, this fails with the following error:
Final Error 0xe0001201. For this operation, the backup Exec Virtual File Filter (VFF) must be installed on the media server.
The job fails immediately once it's started.
No other data is being backup up by this job and the information store is on another server that has the remote agent installed. I can backup file and folders but the exchange environment is not playing ball.
