   • ASwitch to continuous database log shipping to a standby server, with the standby ready to be promoted within minutes.
   • BKeep the nightly full and daily incremental backups, but perform a test restore quarterly to verify the tape media.
   • CAdd a second nightly full backup stored offsite to protect against site-level disasters.
   • DReplace the daily incrementals with a weekly differential backup to reduce the number of tapes to restore.

   A company's disaster recovery plan specifies an RTO of 6 hours and an RPO of 24 hours. The backup team performs nightly full backups and tests restores every quarter.
