# Why are Delta Trust and Delta Drive kept separate?

Because backups and working files need opposite rules. A working drive has to let you delete and overwrite things; a backup is only worth having if nothing — including a mistake or ransomware on your Mac — can delete or overwrite it.

So Delta Trust and Delta Drive are two halves with different protections. Delta Trust also stays where it is when you change working drives: switching from Delta Drive to My Drive never moves or touches your backups, and a working drive is never treated as a substitute for them.
