Симптомы
Microsoft Windows backups fail with the following error:
VSS OTHER: ERROR: VSS failed to process snapshot: Insufficient storage available to create either the shadow copy storage file or other shadow copy data. (VSS error 0x8004231f)
90108:save: Unable to save the SYSTEM STATE save sets: cannot create the snapshot.
Причина
Разрешение
Ensure that adequate disk space is available on the client.
This issue can be replicated without NetWorker by running the following commands on the client:
vssadmin list writers
Your VSS writers should all be listed with "No Error" and "Stable"
If the above completes successfully, run the following command:
vssadmin create shadow /For=Driver_Letter
If a snapshot is successfully created, you see:
C:\Windows\system32>vssadmin create shadow /For=C:
