Informix XPS databases are backed up and restored from third party command line (ON-Bar) utility. In a multi-coserver environment, you can configure the XPS database backups in one of the following modes:
-
Install the iDataAgent on one of the coservers (Primary node) , and configure the instance for this coserver (Primary) from the CommCell. You can use this instance to perform backup and restore operations on all the coservers.
-
Install the iDataAgent on all the coservers which have storage managers, and configure the instance in CommCell Console for one of the coservers. The coserver for which you have configured the instance in CommCell console should be specified in the onbar-worker.
