Disaster recovery explained


The setup used to mitigate the risk of IT downtime is called disaster recovery. It combines scheduled off-site backups, and failover systems to run the post-disaster environment directly from the backup. This sounds complicated, but there are really only two factors to consider to manage IT risk: data and time.

In case of disaster, you can only recover your data from the most recent off-site backup. However, the data that has changed between your most recent backup and the disaster are lost. The time between backups is called the Recovery Point Objective (RPO). This is the most data you risk losing should the worst happen.

Once your system is down, the second variable is the amount of time between a disaster and before your business can be operational again. This is called the Recovery Time Objective (RTO).

Penta offers various RPO and RTO packages adapted to your regulatory requirements:

  • RPO 24 hrs – RTO best effort
  • RPO 24 hrs – RTO 24 hrs
  • RPO 24 hrs – RTO 12 hrs
