You're running RAC, so I assume this is all on-prem.

What is your storage solution? If it's EMC, for example, you could do BCV backups and easily restore from BCV in less than two hours. I'm on AWS, and our largest database is over 12 TB, quickly approaching 13 TB. We take AMI snapshots daily, and if necessary, I can restore from AMI backup in about 15 minutes.

It really depends on your storage technology.

If you're strictly relying on RMAN (or traditional non-RMAN) backups, copying files, I'm not sure you can restore 13 TB in two hours. I guess there's a chance, if you have the CPU and I/O resources and run recovery in parallel.

I just saw Tim's comment come and ,and he, of course, offers an excellent suggestion, and probably far cheaper than my suggestion about storage snapshots, unless you already own the technology.
