To back up GroupWise data in a Linux cluster, you can use the GroupWise Database Copy (DBCopy) utility to copy the data from the live GroupWise system to a static location for backup. For more information, see Backing Up GroupWise Databases
and GroupWise Database Copy Utility
in Databases
in the GroupWise 2012 Administration Guide.
To restore data in a clustering environment, you must run your backup/restore software on the node where the location to restore is currently mounted.
