A backup system override may be specified to allow a backup system to access a backup created on an old storage device. For example, an archival backup may be accessed long after the storage device that created the backup has been decommissioned. The file history information in the backup may specify a storage device no longer accessible by the backup system. An override in the backup system allows the backup system to access the backup with the file history information through a different storage device than the storage device that created the backup. The different storage device may have a different name and/or be of a different type than the original storage device that created the backup. The override may also allow access to command scripts and links in the backup.
