Hello,

I would like to know how exactly backups work for compressed Oracle DBs on a Exadata platform.

Does it need to rehydrate the data before sending it to a mediaagent?

If so, is there any specific requirement for that to happen? like extra RAM or extra disk?

Is it the same for non Exadata environments?

Thanks!

Sergio.

Hi @Sergio V

Use RMAN compression to Basic and enable commvault level compression
