Delta Drive, Delta Trust & My Drive · Delta Trust backups
Can I or Storage Studio delete backups in Delta Trust?
Short answer: No — not during the protected period. Nobody, including you and us, can delete or overwrite what's already backed up in Delta Trust for a set number of days. That's the point of the lock.
Not during the protected period. What has already been backed up to Delta Trust can't be deleted or overwritten by anything on your Mac — including you — or by us, for a set number of days. That's deliberate: a lock you could switch off would also be a lock ransomware or an intruder could switch off.
Older versions are thinned out over time so the backup doesn't grow forever, and if you need a place you can tidy freely, that's Delta Drive. Backups you send into Delta Drive's _Backup folder can be deleted like any other file — which is also why they aren't as safe.
