After many months of error-free backup, I’m now seeing the dreaded ‘Shadow copy was probably deleted while indexing.’
The server is on a Windows 10 machine, and the client is also on a Windows 10 machine.
Here’s the relevant section of the backup log:
03/04/20 13:36 ERROR Error while getting files in folder “\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy2786\Users*****
Windows errorcode: 3. Access to root directory is gone too. Shadow copy was probably deleted while indexing.
03/04/20 13:36 ERROR backupcom->DeleteSnapshots(dir->ref->ssetid, BJECT_SNAPSHOT_SET, TRUE, &dels, &ndels) failed . VSS error code VSS_E_OBJECT_NOT_FOUND
03/04/20 13:36 ERROR Deleting shadowcopy failed.
I realize that there is a FAQ entry for this sort of problem, but it appears to be a little out of date. In particular, the System Protection panel does not mention VSS, but sort of implies that the amount of disk page you are reserving is for restore points. I wonder if space for VSS is still configurable.
However, disk space doesn’t appear to be a problem. The client disk size is 912 GB, of which 249 GB are used. 10% (90 GB) is reserved for system protection.
I would love to have any suggestions about how to trouble-shoot this issue.
