4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

Back up and restore the matrix configuration
It is important to back up the cluster configuration whenever changes are made. You
can then easily restore the cluster if necessary.
If you are using Matrix Server disk quotas, you should also back up the Matrix Server
quota information after backing up your PSFS filesystems.
Back up and restore Matrix Server
HP recommends that you back up Matrix Server whenever the matrix configuration
or the membership partitions are changed. You should make separate backups for
each node in the matrix.
To perform a backup, make a copy of the following directory (%SystemDrive% is
the drive where Matrix Server is installed):
%SystemDrive%\Program Files\Polyserve\MatrixServer\conf
To restore the matrix configuration, use the appropriate utility to restore the conf
directory.
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 104.)
It is possible to save much of the cluster configuration with the mx matrix dump
command. See the HP PolyServe Matrix Server command reference guide for more
information.
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.
