ORACLE DATABASE BACKUP ISSUE (SLOW)

Matheus MathJul 10 2025

Hello, have a great day / night!

I’m currently facing a critical performance issue with backups on a 20TB Oracle database (SAP environment). The current backup process (online backup), scheduled via Windows Task Scheduler, is taking an excessive amount of time, about 15 days.

Here are the key details:

  • Database size: ~20 TB
  • Platform: Windows Server
  • Backup method: Currently using OS-level script via Task Scheduler (not yet using RMAN)
  • Backup destination: Fileshare disk

I'm exploring the use of RMAN ( Recover management) to improve backup time, i am looking for a SAP Note or an Oracle Guide to help me.

Thanks in advance! I apreciate any help!
