Achieving the RTO

  • Factors affecting RTO

    • Size: More data takes longer to backup and recover.

    • Physical access to backups: May be offsite.

    • Frequency of backups: Reduce the amount of transaction data to re- apply and/or processes to re-run.

    • Validation: Integrity checks.

  • Exploit existing backup/recovery software

    • Faster hardware (backup to disc, faster tapes, etc.)

    • Parallel processing.

    • Configuration.

  • Invest in new technology

    • Disc mirror splitting (e.g., EMC’s BCV system).

  • Allow for the worst case scenarios

    • Failure just before or during the backups.

    • Out of hours failure.

Achieving the RPO

  • RPO zero

    • Backup all changes when they occur

  • RPO n

    • Backup changes more frequently than n.

  • Capture ‘change’ information wherever it is needed

    • Transaction data.

    • Code changes.

    • Interface files.

    • Anything else important to your environment.

  • Monitoring processes required

    • Backup more frequently than the RPO.

    • Or when changes occur. (complex)

    • Ensure that they complete successfully within the desired time window.
