In honor of the upcoming Pirates of the Caribbean movie, let me introduce the Pirate Backup System (ARR). ARR, besides a bit of pirate talk, stands for Automatic, Redundant, and Restorable. Meeting those three goals makes a good backup system. Meeting only two will lead to disappointment. Meeting only one describes about two thirds of small businesses today.

I'm working on a “How To Fix IT Manual” called Data Safety Using the Pirate Backup System (ARR). But focusing on backup sends the wrong message, because backing up files does nothing. Users only get value when they restore files. Backup is just the necessary pain to reach the gain of restoring important data files when they are lost, stolen, or mangled. Think of backup as the insurance premiums, and restoration as the replacement payment after a loss.

The first A in ARR, Automatic, forces businesses to take into account the point made in the previous paragraph: users get no value from backup. Hence, users don't back up. One may consider this short-sighted, but users will complain that participating in any backup procedures means they're doing the administrator’s job, not their own. Since data safety is our goal here, let's not argue with the users about this today, let's just work around those issues.

To be automatic your backup system must work without any user intervention. You can't even trust users to leave their computer turned on for a backup job to run at 3:00 a.m. You certainly can't trust them to click an icon to run a backup.

These restrictions leave two options: data must be saved somewhere besides PCs, or you must place software on each computer that works without user intervention.

The first option, the neatest, stores all user data files on some type of centralized file server or even a shared online workspace. That would be great, but realistically you will need to install software on each computer to back up data files on a schedule or immediately upon every file change. Almost every backup software application will schedule backups on at least an hourly basis. To grab file changes immediately you will need special software from the Continuous Data Protection (CDP) range of products.

Second, redundancy protects data files, and makes disaster recovery possible. Companies learn the hard way that backup tapes sitting beside the server burn up when the server burns up. They also learn backup network-attached storage devices get stolen when thieves steal their servers. You must keep copies of data files somewhere outside your business to recover from a wide variety of disasters small and large.

You missed the 'S' for 'ARRS' By Anonymous on November 2, 2009, 3:26 pmUnfortunately, without the 'S' for Scalable, any backup solution (even ARR) is just a band-aid that ignores a gigantic green elephant standing the middle of the...
