The 3-2-1 Backup Rule for Disaster Recovery
You never know when disaster, natural or otherwise, will strike, and if the fate of your company rests on your shoulders, you've probably stopped to think to yourself, "Gee, I wonder how we would fare if our server crashed..." If this thought has never crossed your mind, hopefully that changed upon reading the previous sentence.
In such a technology-driven world, we often take for granted how much our computer network actually does to keep our businesses running. I've said it before and I'll say it again- Your business computer network is the lifeblood of your operation. I've seen people lose their mind because they can't find an email or they accidentally deleted a file. Now imagine that you lose your entire server to some kind of disaster (it crashes, a pipe bursts and floods your office, it catches fire, and so on). No one wants to face these things, but the reality is it can (and does) happen. But, there are things you can do to ensure that recovery is as quick and as painless as possible.
It is imperative to have a disaster recovery plan in place. A disaster recovery plan provides a step by step on exactly what will happen in the event of a disaster. We've worked with businesses to develop complete disaster recovery plans when it comes to the business technology, but today, I'd like to share with you "The 3-2-1 Backup Rule for Disaster Recovery."
1. Maintain (at least) 3 Days of Backups: Typically, we maintain backups for more than 3 days. The more copies of your data you maintain, the less likely you are to lose everything. For the purpose of this rule, however, you should be maintaining no less than 3 days' worth of backups.
2. Store Backups on 2 Different Storage Devices: You should be backing up to two different media. If you're backing up to a NAS (Network Attached Storage), consider backing up to an external hard drive as well. If you're still using a tape backup, consider looking into a more reliable/modern solution. Tape backups leave room for human error and have much higher fail rate than other more modern backup solutions.
3. Send 1 Backup Offsite: With all the different available means for backup nowadays, you can actually kill 2 birds with one stone by doing a cloud-based backup. This covers a second storage device and an off-site backup. Some people will cover this step by using an external hard drive as the second backup device and taking that home with them, but then there's the possibility of human error (misplacing the drive, backing up incorrectly, etc.).
Electro-America's backup model covers no less than 2 weeks' worth of backups. Backups are done internally and stored on a NAS with backups also being performed and maintained off-site at our data center.
