Backing Up a GroupWise System

in a NetWare Cluster
®
The GroupWise Target Service Agent for File Systems (TSAFSGW) is a GroupWise-specific API
that works with compatible backup software to provide reliable backups of a running GroupWise
®
system on NetWare 6.5. TSAFSGW can be used in a clustered GroupWise system with
appropriate preparation and understanding of how the TSAs work. For background information
about the GroupWise TSAs, see "GroupWise Target Service Agent" in "Databases" in the
GroupWise 8 Administration Guide.
In a clustering environment, TSAFSGW must be installed and loaded on each node from which your
backup software backs up any portion of your GroupWise system. To accommodate the variable
locations of data to back up from a clustered GroupWise system, the file for TSAFSGW on
.ncf
each node should be edited to include a /home startup switch for every domain and post office on
every shared volume that might ever be mounted on that node.
If you are using TSAFSGW, the /vserver switch enables you to specify the name of a virtual server
in your NetWare cluster. Then you can use the /home switch to specify shared volumes and paths
rather than physical volumes and paths. For example:
/vserver-clustername_volumename_SERVER
/home-volumename:\domaindirectory
/home-volumename:\postofficedirectory
For example, if you have a domain named NewYork and a post office named Engineering, with
libraries named Design and Training, the switches for TSAFSGW would be:
/vserver-CORPORATE_GROUPWISE_SERVER
/home-gw:\gwsystem\newyork
/home-gw:\gwsystem\engineering
You can use this same configuration file on every node in the cluster. TSAFSGW can identify the
libraries based on information provided by the post office. Your backup software would then list the
following locations to back up, based on the previous example:
GroupWise Cluster System
[DOM] newyork
[PO] engineering
[DMS] lib0001
[BLB] design_store
[DMS] lib0002
[BLB] training_store
From the list provided in your backup software, you can select GroupWise Cluster System to back
up all the objects listed, or you can select individual objects for backup.
When TSAFSGW runs, it backs up the shared volumes that are currently accessible and skips shared
volumes that are not currently accessible. If a shared volume migrates, you must restart TSAFSGW
so that it can re-determine what shared volumes are currently available for backup.
