Backup Procedures
NAS stores 31 daily snapshots. In addition, full backups are taken monthly with incremental backups taken daily. The monthly backups are stored off-site for seven years. With both methods considered, we can restore to any of the past 31 days if the file(s) existed during the time of either the snapshot or the backup, to one of the full monthly backups from up to seven years prior. Oracle Database is run in archive log mode and all redo logs are backed up daily. Hot backup of all data files are done on weekends. Recovery Procedure: Helpdesk tickets to OIR as Priority 1 can restore file(s) in 2 hours time if restoring to a point within the past 31 days. If later (as tapes must come from off-site) expected Priority 1 recovery time is 5 hours.
Disaster Recovery

If later (as tapes must come from off-site) expected Priority 1 recovery time is 5 hours. Major Disaster Recovery: OIR has a written policy on how to handle major disaster recovery.
