What encryption does Data Backup use?
Short answer: We don't publish the technical details, but your files are encrypted on your Mac before any cloud upload, the provider only stores scrambled data, and your passphrase is the only key. Choose a long one and keep it safe.
We don't publish the details of how backups are encrypted, but here's what it means for you: your files are encrypted on your Mac before a cloud backup uploads anything, the provider only ever stores scrambled data, and the passphrase you choose is the only way to open a cloud backup.
The practical things that matter most are in your hands: - Choose a long passphrase — a short sentence is easy to remember and hard to guess. - Store it somewhere safe and away from the Mac. - Never reuse a password from another account.
