Data retention

Once your computer's files have been backed up, the original and subsequent versions persist in the archive until specific time intervals are met.

The default client configuration is sufficient for most users. The default configuration will back up only user data. No system data will be backed up. In some cases, users may wish to modify settings to fit specific needs.
