Backing up the DPM Application
Backing up the DPM application consists of backing up the DPM database and the replicas on the disks it
is managing.
The DPM database is a Microsoft SQL database instance managed by a special Microsoft SQL Server
installation. The Data Protector Express SQL agent separates the DPM database from any other database
instances on the server to ensure that it is backed up only once and to indicate that it is part of the DPM
application. Other instances will only exist if there is an additionl Microsoft SQL installation on the
server.
Likewise, the replica content is separated from other files protected by the Data Protector Express File
System agent. Data Protector Express provides the interface the user needs to backup and restore replica
data. While the replicas are stored in the file system, the File System agent will not show them. Rather,
the Data Protector Express DPM agent will show these files. This ensures that the replicas don’t get
backed up twice.
Replica content is found under the DPM agent path in Data Protector Express :
\Network\<Server-Name>\Data Protection Manager\Replicas
When replica content files are selected for backup, the backup will also create an entry in the Data
Protector Express catalog at the
production server path
that indicates where that the files originally
came from so that they can be restored directly to the production server. The backup will create an
instance for each path when the file is backed up even though the file is stored only once on tape.
The picture below shows both DPM agent paths and production server paths.
