You
can implement external backup
tools to back up and restore MaxDB database systems. Data is transferred
through named pipes, using the
Database
Manager.
There are two possible implementations:
·
The external
backup tool is controlled by the DBM
Server.
When data is backed up, the DBM
Server initiates the data transfer from the
database instance
to one or more pipes, and calls the external backup tool to back up the data
in the pipes. If the database system or the external backup tool causes an
error, the DBM Server ends the data transfer and informs the data transfer
partner.
When data is restored, the
client queries the available backups from the external backup tool through the
DBM Server. It then displays the result of this query to the user, and
initiates and controls the transfer of the required backups from the external
backup tool to the database through one or more pipes.

The external
backup tool uses the client application Database Manager
CLI to control the database.
