In addition to backing up the vRealize Hyperic database, you might want to back up other files in your server directory.
You can back up these additional files without having to first stop the vRealize Hyperic server.
conf/ bin/hq-server.sh hqdb/data/postgresql.conf
The contents of these files are stable. Changes are infrequent after your vRealize Hyperic server is installed and configured. Back the files up following installation, and after making changes to the sever configuration.
