The system where Data Protection for Exchange is
installed must be registered to the Tivoli® Storage
Manager server with
a Database Availability Group (DAG) member name.
About this task
The DAG member name owns
and manages all Data Protection for Exchange data
that is backed up to the Tivoli Storage
Manager server
Procedure
- Specify the DAG member name with the nodename option
in the dsm.opt options
file. The dsm.opt options file is
located by default in the Data Protection for Exchange
installation directory.
- To run VSS operations, register DAG member names for more
systems if required.
- Configure the following Tivoli Storage
Manager parameters
when you register your Data Protection for Exchange
DAG member name (system) to
the Tivoli Storage
Manager server:
- MAXNUMMP This parameter determines the maximum
number of mount points that a client node
is allowed to use on the Tivoli Storage
Manager server
during a backup operation.
- TXNGroupmax This parameter determines the
number of files that are transferred as
a group between Data Protection for Exchange and
the Tivoli Storage
Manager server,
between transaction commit points. This
parameter must have a value of 12 or greater.
- COMPRESSIon This
parameter determines whether the backup-archive
client node compresses data before it sends the data
to the Tivoli Storage
Manager server
during a backup operation. For VSS operations,
specify COMPression=Yes in
the backup-archive client options
file (dsm.opt) in the
backup-archive client directory.
