Synchronization keeps locations aligned

Sync is useful when you want changes to appear across devices. That alignment can also propagate a deletion. A second synchronized device is therefore not automatically a historical backup. Look for documented retention, version history and recovery behavior. Know whether a deleted file remains recoverable and how long that protection lasts.

An archive is a point in time

A manual export can preserve a collection as it existed on a particular date. Its weakness is freshness: files added afterward will not be in that archive. A backup schedule helps only if someone follows it and checks the result. Keep dated copies where practical, and do not overwrite your only known-good archive before validating a newer one.

Encryption does not remove key responsibility

If an archive is encrypted before it leaves the device, storage providers may receive ciphertext rather than readable originals. That statement depends on the implementation and does not make the archive invulnerable. A strong secret, compatible format and successful restore remain necessary. Losing the only secret can be as final as losing the only file. Decide where both will live before disaster.

Use complementary protection deliberately

Apple describes iCloud Backup and synchronization as different mechanisms with different coverage. Review your actual configuration rather than relying on an iCloud icon. For an independent vault, ask which data and keys participate in a device backup and whether a separate archive can restore on another installation. Vaultary’s initial direction prioritizes user-controlled encrypted archives; automatic cloud sync is outside the initial promise. The aim is an understandable recovery path, verified with a clean restore rather than inferred from a completed upload.
