Computer Services backs up central servers, the entire email system, and certain personal files in accordance with the following:
Servers which are maintained by Computer Services are backed up to ensure that files which become corrupted or deleted may be retrieved. The standard server backup retention/restore time is thirty days. A full backup is performed once a month and will save every file on the server, including the operating system. An incremental backup is performed once a week and will save every file that has been created or modified since the last incremental or full backup. A differential backup is performed nightly, except for those nights when a full or incremental backup is scheduled, and will save every file that has not yet been saved on a full or incremental backup.
Exceptions to the above may be made with prior administrative approval to accommodate circumstances where the standard backup and/or retention policies need to be overridden. These circumstances may include, but are not limited to, server maintenance, software upgrades, legal requirements, and extended holidays or weekends.
E-mail servers are backed up in full nightly and retained for four days for disaster recovery use only. Individual mailboxes are not backed up and therefore cannot be restored. If a user desires to back up his/her e-mail objects, he/she must move them from the e-mail server to another location such as a folder on his/her own workstation or his/her home directory on BEAR1 or MAGENTA.
Domain controllers are backed up in full nightly and retained for two weeks for disaster recovery use only.
The contents of individual computer workstations (“personal computers”) are not backed up by Computer Services. Should a user desire to back up the files stored on his/her personal workstation, he/she must move them from the workstation to another location such as his/her home directory on BEAR1 or MAGENTA.
Once a week, a copy is made of any full and incremental backups that were performed during that week. The copy sets are removed from the Cheek Hall server room and stored in a remote location for disaster recovery purposes. The daily differential backups are kept in the Cheek Hall server room. By following this procedure, in the event that the Cheek Hall server room and the daily differential tapes stored there are rendered unusable, Computer Services will be able to recover the files stored on the servers as recently as one and no longer than twelve days prior to the disaster date.
