Licensing and updates

License and trial use

O&O AutoBackup is commercial software. You can try it during the trial period; continued use requires a valid license. The purchase and license terms determine how many PCs and users may run it.

Open About to view the license type, licensed version, serial number, and—where applicable—valid-until date. The page also provides the registration and license-release actions.

Release a machine-bound license

Release the license before replacing, reinstalling, or transferring the PC. The application returns to trial state after restart. A transfer is allowed only as described by the O&O end-user license agreement.

Check for updates

O&O AutoBackup can notify you when a newer release is available. Follow the update link, save current work, and allow active backup or restore operations to finish before replacing the application.

After an update, open About to verify the installed version. Existing pairs and backups should remain available, but keeping a separate copy of important data is always recommended.

Getting support

Use O&O Support for license validation, activation limits, download access, or reproducible product errors. Never include your full serial number, backup password, or recovery key in a public request.
