Backups & restore points · Where backups go
Can several Macs back up to the same drive or cloud account?
Short answer: Yes. Each Mac keeps its backups in its own folder named after the computer, so several Macs can share one drive or cloud account without their backups ever mixing.
Yes. Each Mac's backups are kept in their own folder, tagged with that computer's name, so several Macs can safely share one drive or one cloud account without ever mixing their backups together.
Set up Data Backup on each Mac and point their sets at the same destination. Each Mac sees and restores its own versions. The folder name also carries a short identifier for each Mac, so even two Macs with the same name stay apart.
