System Name
Oracle Database - WaterLog
Hardware Description
Oracle NAS (Networked Attached Storage) managed by STS. Raid 6 system with 40 Terabytes of space. OIR Fiber SAN managed by STS. This is the STS mandated storage medium and backed up through Enterprise Backups.
Software Description
Oracle Database Enterprise 11.2.3 NAS mounted and managed through Windows CIFS (Common Internet File System) Expected to use PDF and TIFF file formats. Oracle Exports and Hot online backups are used to backup the data SAN storage from where it is backed up to the Enterprise backups. Expected to use DOC, DOCX, XLS, XLX, PDF, and TIFF file formats.
System Location
STS Data Center South
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.
Disaster Recovery
Recovery Procedure: Helpdesk tickets to STS 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. Major Disaster Recovery: OIR has a written policy on how to handle major disaster recovery. In summary: Order new hardware if required. Receive, configure and verify setup and connect ability. Install required software to restore from image files and/or tapes. Inventory media and image files, restore.
Data Migration Description
Select users in each agency, along with (temporarily)General Services personnel, have the ability to scan and write documents to the NAS. Managed by Active Directory Groups.
