Using VDP to backup Windows 2008 R2 server - upgraded to 5.1.11 to fix the quiesced snapshot issue.
Some VMs are now backing up, but random others are getting this message:
Error code 30915: An attempt was made to backup a client in a group failed because the client does not have any data matching the data target specified in the dataset.
Google searches are proving fruitless.... any clues?
