I am creating backup vaults in AWS Backups for our various resources (RDS, S3, and others). It's going well. However, I was curious - if I create two backup vaults for a single resources (e.g. Snapshots Vault, Continuous Vault) is that inefficient? Is there reasons I should/should not do it that way - additional costs, inefficiency in backup, something else?
(Note: The above is just an example. I have more specific reasons why I might break it out that way, but I didn't want to spell all that out here.)
