Oracle DB version: 19c
OS : Oracle Linux 7.8
I have two RAC DBs in production. One DB is 2TB in size and another one is 1.5 TB. Currently, it is being backed up to DataDomain backup appliance.
I had done test restore+recovery of these 2 DB and following are the time it took.
2TB DB ----> 2 Hours
1.5TB DB ---> 1.5 Hours
Currently, I use Cumulative incremental backup for these 2 DBs.
But, application team wants these 2 DBs to be restored+recovered (be back up and running) 'ASAP', in case of a disaster.
In this case, 'Incrementally Updating Backups' mentioned in the below link is the best option. Right ?
I just have create a new diskgroup for each DB to store the image backups. i.e. The new Diskgroup size should be same as the DB size.
