College servers are mission-critical servers; therefore, they are designed with power and hard drive redundancy to prevent serious failures. The servers are backed up multiple times during the day. In the College of Allied Health, a grandfather, father, son backup routine has been implemented such that intra-daily backups are available for one week, consolidated daily backups go back 15 days, consolidated weekly backups go back 3 months and monthly backups go back at least 6 months. It is feasible to retrieve data as far back as two years. Each backup includes the server operating system and all data. If a file needs to be recovered from backup, the user should notify, Devin Taylor, (405) 271-8001 ext. 43412) providing file name(s), file location(s), and the last known valid date(s) the files existed. To assure physical security, backup images are stored on a redundant network attached to storage in multiple data centers.
