The Tessell Availability Machine provides Zero Data Loss for Oracle databases. The data is protected by Availability Machine in 3 parts

  1. Snapshots: Snapshots are regularly taken, with a minimum of one per day.

  2. Archive Log Backups: Archive logs are backed up every 5 minutes.

  3. Online/Redo Logs: Redo logs are multiplexed and kept on a Premium SSD.

Thus, if ever there’s a database failure, it can be restored to the last committed transaction with the combination of the above three.
