A storage administrator is tasked with creating a disaster recovery solution for an application with Recovery Time Objective (RTO) of two minutes and Recovery Point Objective (RPOJ of five minutes. In

Replication, particularly continuous or near-continuous, ensures that data is consistently copied to a secondary site, enabling rapid failover in case of a complete site failure. This directly contributes to meeting a low Recovery Time Objective (RTO) of two minutes.

Content Addressable Storage (CAS) is primarily for archiving and immutable storage, not for active application disaster recovery requiring low RTO/RPO.

Tape backups typically have much longer recovery times (hours to days), far exceeding the specified two-minute RTO.

Snapshotting provides point-in-time copies of data which, when taken frequently (e.g., every five minutes or less), directly addresses the Recovery Point Objective (RPO) of five minutes. These snapshots, when combined with replication, offer granular recovery options at the disaster recovery site.

Virtual Tape Library (VTL) backups, while faster than physical tapes, still involve a restore process that would likely exceed a two-minute RTO and five-minute RPO for a complete site failure scenario.
