How to backup huge SAP Database?

Hello,

I am looking for new solution for backup big SAP DB 17 TB / 300 GB changes/per month

For now we are using customized scripts using flashcopy from DS8000 (source for this DB). Flash is being mounted via media server and goes to tapes via SAN using RMAN backup (to tapes).

We have upgraded recently NBU to 7.7.2 and we bought 4 x 5330 Appliance as media servers 4 x 200 TB

What backup solution do you suggest?

I have read about Oracle Copilot, what do you think?

There is also Client snapshot for SAP

Or maybe use standard RMAN backup via Oracle Int Policy ?
