Disaster recovery

A standby ready to take over

We set up standby databases at a second site, test the switch regularly, and document exactly what happens when the primary fails.

  • Changes shipped continuously to the standby
  • Automatic or manual switchover, tested on a schedule
  • Applications reconnect to the new primary
