Cause
- Another VSS-aware backup is set up with the same schedule. There is backups overlap.
2. Microsfot issue introdused with KB2919355 update from April 2014. After the update, Hyper-V backup started returning AutoRecovery.svhdx path without "\" (backslash) sign.
Workaround
- Check if a backup overlap exists on the back up computer/server. To avoid overlapping, re-schedule different backup tasks to different time. If it did not help, follow the next:
2. Apply the Microsoft KB 3135020 "Recommended hotfixes, updates, and known solutions for Windows Server 2012 R2 Hyper-V environments".
3. For Exchange Server apply the Microsoft KB 3099522 "Cumulative Update 11 for Exchange Server 13".
