The 3-2-1 Backup StrategyĪ 3-2-1 strategy means having at least three total copies of your data, two of which are local but on different media, and at least one off-site copy (in the cloud). Similar to how regular dental cleanings benefit your overall health and keep you from losing teeth, reviewing your backup strategy keeps you from losing your data.įirst, let’s do a quick review of the 3-2-1 backup strategy. In this post, we’ll go over several ways in which the cloud makes managing your data easier and provides you with a number of benefits. And, much like making time for your regular dental checkups, in the long run, you’ll be so happy you made time to set up your backup strategy. While these options are still in use, the cloud has changed everyone’s backup strategy. When it first appeared, the preferred technology included rotational tape, recordable media (CDs, DVDs, and SD cards), and external hard drives.
The industry standard is the 3-2-1 backup strategy. If you are currently juggling hard disk drives between workstations and an off-site location or you’re using network-attached storage (NAS) to store company files, you may want to consider adding the cloud to your backup approach to make those backup best practices easier to actually practice. Most business owners know that backing up their data is a standard best practice, but like a lot of things that are good for us, like getting your teeth cleaned or eating kale, putting best practices into actual practice can sometimes be a challenge. Since then, we have updated this post with the latest information on the cloud and backup best practices.
