Description of problem:
Cluster Configuration does not automatically create a backup copy of the cluster
configuration file (/etc/cluster/cluster.conf) when the cluster configuration
file is saved. Not automatically creating a backup copy of the cluster
configuration file limits a user's ability to restore to an earlier cluster
configuration in case of a configuration error. For example, refer to the RHCS3
Version-Release number of selected component (if applicable):
Change configuration, save configuration file, and propagate the configuration.
Then at the node where the configuration file was modified, search for a backup
file with a file name extension of .bak. None is found.
Fixed in 0.9.49
