MaxDB guarantees the high availability of your database by supporting the setup of standby databases.
A standby instance is a copy of the active database instance (original instance). To keep the contents of your database up-to-date, the log backups of the original instance are imported at regular intervals. The standby instance always has the operational state ADMIN.
If you experience problems with the original instance, you can start operating the standby instance immediately, and carry on working without a lengthy period of downtime.
Depending on the configuration, you can also restore the standby instance to a specified state in the past.
