For durability and reliability, it is a good idea to back up an enhanced cluster’s shared data store periodically to backup files. This creates a snapshot of the data store that you can then use to restore the data in case of catastrophic failure. The command for backing up the data store is
imqdbmgr backup -dir backupDir
where backupDir is the path to the directory in which to place the backup files. To restore the data store from these files, use the command
imqdbmgr restore -restore backupDir
