The ZFS solution is comprised of two separate systems – a production system and an archive system. The production system is comprised of both primary and disaster recovery (DR) hardware. The archive system is comprised of low-speed disks.
Data is replicated every 30 seconds from the primary system to the physically disparate DR system. Snapshots of data that has been changed or deleted on the ZFS system are taken five nights a week. Thirty snapshots or 6 weeks of changed data are stored, insuring that any accidental changes or deletions of data can be recovered.
All storage is leased on a quarterly basis. If you would like information about SDS rates, email Steve Wiese.
