ERP 9 backup

I need to backup my database and run PROENV index rebuild. What is the correct order to stop and restart the database? Do I need to stop and restart AppServer, Process Server and task agent? In what order to stop and restart please.

Or, if I just want to do a backup, can I leave those alone and just stop the db, run backup, and restart the db?

I always used “Reverse Alphabetical Order”:
Task Agent
Process Server
App Server


Maybe the proenv/probkup “online” option?
