One some of the backup destinations, there is space being used that isnt required. I deleted some backups that were no longer needed. VDR can use the space, but the space is still taken up on disc. So VDR might be saying that the destination is using 400GB. But if I do a du -hs on the virtual machine, it says 879GB.
This creates a problem as currently I copy these backups to external drives to go offsite, and space is becoming a problem. Is there a way I can clear up this extra space?
