To restore backed-up data from Wasabi Hot Cloud Storage, the local copy of the tape needs to be deleted. In order to achieve this, choose one of two options.
Option 1:
Navigate to VTL storage location (Default location is C:\VTL\VTL.swdsk.tapes)
Locate the .VTdat file and delete it.
Option 2:
Navigate to Cloud Replication configuration on the VTL.
Edit Cloud Replication settings and change the Keep local copy after the file has been replicated days setting from Never Delete to Delete Immediately.
Both these options allow Starwind VTL software to ensure restoration can be achieved.
