Question
A financial services company has a requirement to keep backups on premises for 30 days and off-site for up to seven years to a location that is within 100mi (161km) of the primary datacenter location. Recovery times for backups kept on-site have an RTO of one hour, while recovery times for backups kept off-site have an RTO of four hours. Which of the following solutions BEST solves this requirement?
Options
- AImplement a full-based backup and recovery solution for backups within 30 days or
- BImplement a clone-based backup and recovery solution for backups within 30 days or
- CImplement an incremental-based backup and recovery solution for backups within 30
- DImplement a snapshot-based backup and recovery solution for backups within 30 days

Why each option
To meet the RTO requirements for both on-premises (1 hour) and off-site (4 hours) backups, with varying retention periods, a clone-based backup and recovery solution is the most suitable choice. Clones offer the fastest recovery times as they are full copies ready for immediate use, directly addressing the stringent RTOs.
While full backups are self-contained, they can take longer to perform than clones and might still require a restoration process that exceeds the 1-hour RTO.
A clone is an exact, independent copy of a system or data that can be immediately brought online or restored without requiring a lengthy process of merging multiple backup files, directly supporting the aggressive RTOs of one hour for on-site and four hours for off-site backups.
Incremental backups require the restoration of a full backup plus all subsequent incremental backups, significantly increasing the recovery time (RTO) and making them unsuitable for the specified one-hour and four-hour RTOs.
Snapshots are point-in-time images, often used for immediate rollback on the primary storage, but are typically not considered long-term, independent backup solutions that are moved off-site or retained for years like clones.
