Changing a cloud photo library can mean three different things: keeping selected files local, replacing the photo service, or encrypting files before placing them with an existing provider. Choose the intended outcome before choosing an app.
Compare the three paths
| Path | Useful when | What you must still arrange |
|---|---|---|
| A selected local NullVault archive | You want separate private spaces for media, documents and notes | A tested backup and a protected recovery credential |
| An encrypted photo-library service | You want collection-wide photo backup, discovery and sharing | Account and encrypted-data recovery, plus recipient-copy handling |
| Client-side file encryption | You want to keep a compatible storage provider and file workflow | Compatible clients, credentials and verification of synchronized copies |
The Ente Photos comparison, Proton Drive comparison and Cryptomator comparison describe those different workflows and link to the vendors’ documentation. Their presence here is not a claim that they have identical features.
Avoid solving the wrong problem
If your problem is a person using an already-unlocked phone, changing the cloud provider alone may not address it. If your problem is a device becoming unavailable, storing everything only on that phone can make recovery worse. If your problem is an existing recipient copy, neither a new vault nor a new cloud service retrieves it.
Migrate in reversible steps
Export a sample, check original quality and content support, and test recovery at the destination. Then decide how much of the library actually needs to move. Keep the old copy until verification is complete and document any shared albums or exported files that remain outside the new arrangement.
Read local vault versus cloud storage and cloud sync versus encrypted backup for the underlying distinctions.
