Rolling back an update

If an update causes a problem, stop and contact support before installing an older version.

A rollback is supported only after we confirm the exact version you have, the version you want to return to, your operating system, and your installer type. Compatibility is checked for each pair of versions. It is not safe to assume that any old MomentBackup can read data written by any newer one.

Replacing the app does not itself delete the backup repository. However, an older app may not understand newer settings, repository data, or repair information. That is why the compatibility check comes first.

Before you start

Let any backup, restore, verification, or repair finish. If anything is stuck, stop and contact support. Do not replace the app until the operation has stopped safely.
Pause automatic backups until the checks at the end of this page pass.
Finish or cancel encryption setup, especially if you have not saved the recovery key.
Ask support for the exact official installer and its SHA-256 checksum. Not every previously published package is retained yet. If we cannot provide the exact installer, or its checksum does not match, do not continue.
Never use an installer from a search result or a third-party download site.

Support will also tell you about any version-specific limits. For example, an older version may temporarily be unable to use newer self-healing redundancy data even though ordinary file restore remains compatible.

Install the confirmed older version

Windows

Use the exact .msi or .exe and instructions supplied by support. Some version pairs can install the older package directly. Others require uninstalling the app first. Do not guess: the rule is set by the older installer being run.

macOS

Quit MomentBackup. Open the verified disk image and drag the app to Applications, replacing the copy that is there. If macOS says it cannot verify the developer, stop. Do not bypass Gatekeeper; ask support for a correctly notarized copy.

Linux

Quit MomentBackup first. Use only the package whose checksum support gave you.

For a .deb:

sudo apt install --allow-downgrades ./MomentBackup_<version>_amd64.deb

For an .rpm:

sudo dnf downgrade ./MomentBackup-<version>-1.x86_64.rpm

For the AppImage, replace the file in the same folder, with the same filename as the one you’re running. Scheduled backups point at that exact path, so moving or renaming it may make the schedule fail because it still points at the old path.

After you roll back

Before allowing the next automatic backup to run, confirm all of these:

MomentBackup reports the expected older version.
Your existing snapshots appear in History.
Verification completes without a new error.
One small, non-critical file restores with the expected contents.
Your automatic backup schedule still points at the installed app.

If any check fails, quit the older app and contact support. Do not repair, migrate, or delete the repository while the rollback is in doubt.

Still stuck? Email [email protected] and include what you were doing and what you expected.
