We do incremental forever using incrementally updated image copies with
additional help from backup storage. All scripts and method is described

Have not had any problems backing up and doing daily restore tests with
busy 160+TB databases and smaller 20-50TB ones.

Hi there,
The database for our critical Banking application is 13 TB, and our RTO
(Recovery Time objective) is 2 hours. We are running on 12C and have 3
nodes RAC clusters in both Prod & DR and have Active Data Guard set up too.
But our company's Audit & Risk compliance team has flagged us with VLDB
break asking us how would you restore your large DB from the backup in 2
hours if there will be any Cyber Attack and corruption gets propagated to
DR. I know this kind of restore/recovery may not be required ever, but we
still have to prove that we have a strategy in place to meet our RTO of 2
hours in case we have to restore from backup. I would like to mention that
we have to keep at least 8-10 years of data in our DB for compliance
purposes.
I know there might be lots of DBAs on this forum who could be supporting
VLDBs, can you please share how have you implemented VLDB recovery
solutions for your DBs?
Thanks,
Harinder Singh
