Choosing the proper catastrophe restoration as a service (DRaaS) software program empowers companies to implement highly effective options that meet their RTO and RPO goals with minimal knowledge loss.

On this article, we’re going to debate find out how to measure RTO and RPO, the position of those metrics in a backup enterprise continuity plan, and find out how to outline and obtain your small business’ RTO and RPO targets.

For these causes, CDP is extensively used for file-level backups.

Close to steady knowledge safety could be set to close zero and run at common intervals.
