3.6.0 Matrix Server 3.6.0 Administration Guide (5697-7081, December 2007)

Chapter 4: Matrix Administration 39

NOTE: Be careful not to accidently back up PSFS filesystems multiple

times by using both your site-defined drive letter/mount point

assignments and the reserved mount points created by Matrix

Server. Filter out the reserved mount points from backup jobs, and

instead use your own site-defined assignments. (For more

information about the reserved mount points, see “Differences

Between Matrix Server and Microsoft Utilities for Volumes and

Filesystems” on page 96.)

Back Up and Restore Membership Partitions

The membership partitions contain three databases that need to be

backed up:

• The device database, which contains information about imported

disks.

• The volume database, which contains information about dynamic

volumes.

• The mxds datastore, which contains matrix configuration information.

The device database and the volume database are automatically backed

up to the file conf\MP.backup whenever they are changed; your backups

of the conf directory will always contain up-to-date copies of these

databases.

The mxds datastore is automatically backed up to conf\MPmxds.backup

once-per-day. If you make configuration changes to the matrix, you may

want to make a backup copy of the mxds datastore to ensure that you

have an up-to-date backup.

Use the following command to back up the mxds datastore to the default

backup file, conf\MPmxds.backup:

mpdump -X

Use this command to back up the mxds datastore to the file of your

choice:

mpdump -x <output-file>
