If OpManager use external database, will both configuration file and data file store in external data?

if i want to perform regular backup, should I backup external database only or I also need to execute "/bin/backup/backupdb.bat -mode configdata" as well? to have configuration backup?

# Usage : sh BackupDB.sh [-mode (configdata)] [-destination (destination directory)] [-threads (1-15)] [-debug]

Thank you
