Review the following settings when registering your Data Protection for Exchange DAG member name.
The system where Data Protection for Exchange is
installed must be registered to the Tivoli® Storage
Manager server with
a DAG member name.
This DAG member name
owns and manages all Data Protection for Exchange data
that is backed up to the Tivoli Storage
Manager server.
Specify this DAG member name with the nodename option
in the dsm.opt options file located (by default)
in the Data Protection for Exchange installation
directory. To run VSS operations, you might be required to register DAG member names
for more systems.
Use the following
Tivoli Storage
Manager parameter
conditions 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 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.
