ImageMaster Archive Recovery Management

The Archive Recovery Management (ARM) Service of ImageMaster increases redundancy on archive level. It keeps archiving processes up and running in situations when a physical storage is temporarily unavailable. An administrator can put the unavailable storage into maintenance mode to suspend archiving to this storage. If there is a redundant physical storage (see chapter Archive model), the archiving process continues using this remaining storage. Once the connection to the unavailable storage is restored, the administrator turns off the maintenance mode to resume archiving to all storages. A recovery process can then be run, which resynchronizes the content of the two storages.

Beside the ARM service, where an administrator can manually put an archive into maintenance mode, ImageMaster also supports auto recovery in environments where redundant storage has been set up. In case of an outage, with auto recovery there is no need for manual intervention by an administrator to rectify synchronization discrepancies. After the redundant storage unit has been recovered, fully automated processes will resynchronize the storage units.

Archive Recovery Management and auto recovery in general facilitate storage reliability and availability, especially if redundant low cost storage systems are used in the archiving solution. These features have been designed to work independently from the used storage system. A completeness check is supported to verify the consistency across the database and the archive storage.
