An organization maintains a cloud-hosted database that requires backups to be able to restore operations to the state at the end of any given business day in the event of a failure. Recovery of the data must be possible within 2 hours to meet their Recovery Time Objective (RTO). Which backup policy should the organization implement to BEST meet these requirements?
You selected this option
Hourly incremental backups with a weekly full backup.
You selected this option
Continuous snapshots throughout the day with no full backups.
You selected this option
Daily full backups with offsite storage replication.
You selected this option
Weekly full backups and daily differential backups.
Performing daily full backups ensures that the organization can restore operations from any given day, meeting the requirement for daily state recovery. Full backups are self-contained which simplifies and expedites the restore process, allowing the organization to meet the 2-hour RTO. Incremental backups would require all the backups since the last full backup to be restored, which could extend beyond the 2-hour RTO. Differential backups, while faster to restore than incremental backups, still involve more complexity and time than full backups to achieve a daily state recovery. Lastly, snapshots may be fast to create but can depend on the existing infrastructure to be intact, and don't always fit within backup policies as a standalone solution for meeting RTO requirements for databases.
