It is extremely important for businesses to have a Disaster Recovery (DR) plan in place for situations where downtime or data loss may affect the business’ ability to continue operating smoothly and effectively. To protect your data, it is essential that you know what you’ve got, understand what’s at risk, and then create a Disaster Recovery plan to keep risk at a minimum.
Disaster Recovery ties directly into business continuity because with so many businesses relying on their websites and/or the Internet in general, the loss of data could greatly affect their revenue. The reality is that if your information system is taken down due to a flood, malware, hack attack, etc., you have both a business continuity and disaster recovery issue on your hands.
When putting together a Disaster Recovery plan, there are several key factors that will need to be considered so that the plan is as effective as possible. Take the following factors into consideration when creating a DR plan for your business:
- Recovery Time Objective (RTO) – What is your business’ objective time in which you should be able to restore systems to a point where you can carry out the impacted operations, even perhaps with limited functionality?
- Maximum Tolerable Downtime (MTD) – How much downtime can your business handle before the impact of this downtime becomes long term and results in substantial loss?
- Recovery Point Objective (RPO) – At what point can your business cope with data loss? This will determine whether your business should implement data backup routines consisting of constant synchronization, daily backups, weekly backups, etc.
Having a Disaster Recovery plan in place will allow your business to recover from disaster in a relatively short amount of time because of the protocols in place to restore lost data, as well as to restore hardware resources that have been affected.
