The back-up schedules and retention are the same, but off-site tape storage is available only for the Networker service.
The standard plan for server backups is to take full backups every week, and incremental backups, (which contain only the data changed since the previous incremental or full backup) every night. In general, the full backups are put on tapes that are shipped to an off campus vendor for secure storage. The incremental backups are kept on-site, either on disk or tapes held in a secure locked area, for one month. Other backup plans can be arranged.
Full backups are retained as follows: weekly full backups are kept for one year, monthly full backups are kept are kept for one quarter, and yearly full backups are kept for three years. File Recovery is included as part of the backup service.
