Yes, you can. In QPS 7, the QPS Server configuration is stored differently from the way it was done in earlier versions of QPS. In QPS 7, the configuration information is saved inside files located inside the folder named Database. The Database folder is located inside the QPS Server application folder.
To backup your configuration, you simply make a backup of this folder and rename the backup to something like Database-backup. In the event that the QPS Server machine goes down, you can simply copy this backed up Database-backup folder and replace it in the QPS Server application folder installed on another machine. Once you have copied it into the correct location, move the Database folder outside of the QPS Server folder and rename the backup folder Database.
