- Goals –what the business hopes to do in the event of a disaster, including the Recovery Time Object (RTO), the maximum length of downtime permitted for each crucial system, and the Recovery Point Object (RPO), the most acceptable level of data loss.
- Personnel – responsible for executing the IT disaster recovery plan.
- IT inventory – list hardware and software assets, their criticality, and whether they are leased, owned or used as a service.
- Backup procedures – how and where (exactly on which devices and in which folders) each data resource is backed up, and how to recover from backup.
- Disaster recovery procedures – emergency response to limit damages, last-minute backups, mitigation and eradication (for cybersecurity threats).
- Disaster recovery sites – a robust DR plan includes a hot disaster recovery site – an alternative data center in a remote location that has all critical systems, with data replicated or frequently backed up to them. Operations can be switched over to the hot site when disaster strikes.
- Restoration – procedures for recovering from complete systems loss to full operations.
No organization can afford to not be prepared. The two most important benefits of having a disaster recovery IT services plan in place are:
-
- Cost savings: Planning for potentially disruptive events can save a huge amount of money and even mean the difference between a company surviving a natural disaster or folding.
- Faster recovery: Depending on the disaster recovery strategy and the types of disaster recovery tools used, businesses can recover much faster after a disaster, or even continue operations as if nothing had happened.
The biggest mistake most businesses make is waiting until after a disaster strikes to figure out what to do next. Statistically, that can be a death sentence for a business. No one has ever gotten into trouble for being overly prepared, but many businesses have failed because they weren’t able to recover from a catastrophic event.
