I have one (Server 2012 R2) guest on Hyper-V in Server 2012 R2 host. System Reserved and C backup completes data transfer and all but Server(Online) fails to complete.
"Failed to complete 0KB of 0KB"
WSB Error: The component Server2012(Online) was skipped during the snapshot and will not be available for recovery. Error: The writer experienced a transient error. If the backup process is retried, the error may not occur.

After running this script: http://www.nullskull.com/q/10115236/issue-with-windows-server-backup.aspx and turning VMMS service off and on, and then restart, backups appear to (or at least WSB says the Server2012(Online)) have completed BUT the data transferred says 0KB of 0KB! Then, the next backups say "failed" or "completed with warnings".
The question is: HOW DO I GET WSB TO WORK?
Thanks in advance, everyone! I appreciate all replies very much.
