Your business’ disaster recovery plan will have a lot of facets involved and it will be complicated, there’s no going around that. The data sets you have in your organization, from file, applications, email, and server all require different handling on their recovery. And when you add in redundancy to ensure business continuity, the plan changes completely in that the main goal now is for all your services to be available instead of recoverable.

It is best to leave the complexities of disaster recovery planning and business continuity to the experts who know all there is to know about it and what to anticipate. However, failures that can accompany this plan can be avoided by following the backup rule of 3, the guideline that defines where proper backup is to be, regardless which data set needs to be protected.

It is a simple formula that consists of the following:

3 copies of your data

You may think 3 is too much and too costly, especially if the data you’re housing is significant both in size and to your company that would require a specialized and secured storage. But repeat after me – losing data and having no recovery options is more costly, what with their legal implications and all. This is just to ensure that you have recoverability. Even if redundancy has been built into the storage, an entire disk array can still fail at your time of need. So the first formula to the rule is to have three copies on any data set you wish to protect.

Your live data is the first copy, so you only need to make two more. You could do this through the use of a hybrid cloud backup and recovery solution that mirrors back up on-premises and in the cloud – creating the two extra copies you need. Another way is to have continuous replication of a VM to an alternative site and a backup of the VM image.

Of course there are other ways to go about having three copies of backup, just make sure that you have.

2 different media

Of course this should come as no surprise that the two extra copies you make should be in different media. Do not store two copies together somewhere as that’s defeating the purpose of the recoverability, especially in the case of a failing disk array. So remember, two copies in two completely different media storage.

1 offsite copy

This last formula ties up loose ends in that in the case of an entire location being wiped out, your data is still secure. Sure, you put in two copies in two completely different media and yet they are in the same building – when natural disasters like fire or flood takes over that building, what happens then? If you’re opposed to putting your data in the cloud, placing one media to a remote data center should do the trick of adding another layer of protection against any type of loss.
