Backups & restore points · Time Machine and backup strategy
Are folders I moved to my fast drive still backed up?
Short answer: Not automatically — many backups only see the shortcut left behind. Give Data Backup's built-in Fast drive working set a destination (not the fast drive itself) and it protects what you've moved.
Not automatically — moving a folder to your fast drive changes where it lives, and many backups (Time Machine included) only see the shortcut left at the original place. Storage Studio covers this with the built-in Fast drive working set in Data Backup: give it a destination and it backs up the fast drive's Storage Studio folder for you.
Choose a destination other than the fast drive itself, so one drive failing can't take both copies.
