Which of the following backup techniques is the MOST appropriate when an organization requires
extremely granular data restore points, as defined in the recovery point objective (RPO)?
Virtual tape libraries
Continuous data backup
The recovery point objective (RPO) is based on the acceptable data loss in the case of a disruption.
In this scenario the organization needs a short RPO. Virtual tape libraries, disk- based snapshots
and disk-to-tape backup would require time to complete the backup, while continuous data backup
happens online (in real time).
