Delta Drive, Delta Trust & My Drive · What Delta X is
What's the difference between Delta Trust and Delta Drive?
Short answer: Delta Trust is for backups that nothing on your Mac can delete for a set number of days; Delta Drive is for everyday files you add, share and delete freely. They're kept apart on purpose.
Delta Trust holds your backups; Delta Drive holds your working files. In Delta Trust, nothing on your Mac can delete or overwrite what has already been backed up for a set number of days. In Delta Drive, you add, change, share and delete files freely, like any folder.
They're kept apart on purpose. As the app puts it: a backup you can delete is not a backup, and a drive you cannot delete from is not a drive. Your backups also don't move if you switch your working drive to storage you own.
