First of all U need check Backup Administrator and find if U set snapshots on initialization time (4,5,6 or more), set just single and delete all old snapshots. Today I've spend a loot of time. When I've delete big files volume not increase. Next step I've start backup data to external drive, and only in backup administrator I've found a lot of snapshots So space are returned!
That not bug - that feature!
