Any basic one node (non-clustered) installation can be backed up to be restored later. In a Bonita BPM cluster, you need to back up the nodes, the shared database, and the shared Bonita home.
How to back up an installation
A cold backup (total shutdown) is recommended, to avoid losing data being processed during the backup process. Note: make sure your database server is backed up. (Please refer to the specific documentation for your database concerning the backup procedure).
