Backups are created automatically by Premiere or After Effects depending on the settings within the respective application. If a backup exists and the system has been configured in the correct way, you can view the existing backups via the Action menu under Restore Saves. Here you can see the name of the backup, when the backup was made and where it is stored. You have a history of all the Auto Safes, so to speak, and if you click on “restore” you can restore one of them. The way the backup is restored depends on the configuration in the backend.
