The 3-2-1 Backup Philosophy

Data Doctors Tech Tips

No matter how technical you may or may not be, there is one thing that everyone knows: backup the data files you care about

.

Because we specialize in data recovery, we've seen virtually every scenario over the past 30 years when it comes to critical data that has been lost.

Beyond equipment failure and traditional data loss, we all now need to be concerned with the growing instances of ransomware.



Just having a local external backup drive isn't enough these days because everything from ransomware to a fire or flood could render that local backup useless.



We recommend the 3-2-1 backup philosophy which means that you have 3 copies of your data on two physical storage devices with one copy that exists off-site, such as an online backup service like Carbonite.

T

hat means that your primary copy lives on your computer's hard drive, the second copy lives on an external hard drive connected to your computer and a third copy is stored in the cloud.

If you do this, it covers every possible data loss scenario that we are aware of at this point in time.
