When I try to start the windows server backup it fails because of empty disk space. I get the following error message in the event log:
The backup operation that started at xxx has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348249'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
The main drive C: has two partitions:
- Windows partition (normal drive you see in Windows)
- System backup (bootmgr, VSS, ...) 100 MB
The system backup partition has only ~5 MB free disk space and fails when trying to back up, but only if I include the system backup partition which is recommended.
I tried to use C: for the VSS files, but still I get the same error. I have enough space on my external backup media so it only has to do with the system backup partition.
How can I make the server backup?
