Image/Data Storage & Archive System
The large amount of data produced by even a single run of a subject for an fMRI experiment requires a large amount of redundant storage (approximately 700 MB per run). We utilize RAID servers (Redundant Array of Inexpensive Disks) which allows a large amount of storage with redundancy in case of disk failure. In addition, a tape backup system is utilized for archival storage of information from the RAID servers. The tape backup/archive system has nightly backups (incremental) run to LTO tapes and the Ultrium Tape Library Monday night through Friday night. Weekly backups (stored indefinitely off-site) are sent to the MagStar tape device on Sunday night. MagStar tapes are sent to the local hospital Disaster Recovery Data Center each Monday and are marked for permanent retention.
