 Because of the need for a backup system, the Computer Science department has implemented the Free/Open-Source backup system called [[http://www.bacula.org|Bacula]]. The Bacula system has an impressive feature set and is very flexible for backups across multiple platforms.

 If you would like another drive backed up, contact the [[support@cs.ndsu.edu|backup administrator]].
+===== Backup rotation and retention periods =====
+==== Backup retention period ====
+At any time, you will have access to AT LEAST one weeks worth of backups. The server may have more than that, but there is no guarantee of having backups older than one week. Based on your client's usage of server space, you may have have access to more than one week. Clients using less space may be allowed to have backups reaching as far back as a month or longer.
+==== Detail of backup retention methods ====
+Initially a full backup is performed on a given computer. After this [[http://en.wikipedia.org/wiki/Full_backup|full backup]], [[http://en.wikipedia.org/wiki/Incremental_backup|incremental backups]] occur on a daily basis until such time that the server needs to reclaim some of its drive space. The server will then select the client using the most space, consolidate their backups into a new 'full' backup (or perform a new full backup) and then after one week has passed, remove all backups for that client which are older than one week.
+This ensures that a full week is stored while minimizing space used on the server. This scheme also allows for more flexibility and the possibility of long retention periods for certain clients.
+===== Restoring files =====
+File restoration through the console is detailed [[backup:restore|here]] but probably no longer works. Ask the System Admin for an archive file of your backed up information.
