In the data storage industry, we use acronyms the way RNs use hand sanitizers – very liberally! I remember the first one I heard that had anything to do with storage. It was in the mid- to late-‘80’s when I was employed by Structured Computer Systems (now e-Plus) which was co-founded by Marv Slayton and Jerry O’Connell. And (this is completely from memory, so excuse me if it is wrong…), it was how an Apple Macintosh spoke to disk on a Wang Laboratories VS minicomputer. It was pronounced “skuh-zee” and the acronym was/is SCSI, which stands for Small Computer System Interface.
Being in the technology field since 1981 (go ahead – look it up), I’ve seen that acronyms flourish. Sometimes Frequently they conflict. For instance, “VSS” has 164 meanings, at least 28 of which are in Information Technology. And acronyms transcend industries, hobbies and interests. They seem to be the next evolution for nicknames in industries. But they aren’t nearly as cool. Stop into the Gear Jammer truck stop in Mountain Home. Idaho and you will hear language that could be so foreign, you won’t know until it shows up that the waitress understood your order. For more diner lingo, click here.
So, why is this acronym, D2D2C, necessary?
Well, we used to have “B2T” (backup to tape). Then, when we started backing up disk arrays to other disk subsystems, we would say we were backing up “D2D”, or disk-to-tape. D2D, especially ten years ago, was used since tape libraries’ drives could not write fast enough to get the job done in the window of time allotted for performing the complete backup. But we still needed to move it offsite, so then came “D2D2T” – yup, you guessed it: disk-to-disk-tape.
Now, as tape is finding its way into its niches (Media & Entertainment, Security, etc.), most companies are using “the Cloud” to backup their data and automatically move it off site. This spawns the “D2C”, or disk-to-cloud approach. The two primary problems with this are:
The better approach, and the one that has been gaining traction: D2D2C, or disk-to-disk-to-cloud. This is the best of both worlds and is often referred to as a ‘hybrid’ approach, which makes sense. I try not to use the word ‘hybrid’ in this context, however, as it is used in more than one area when it comes to the discipline of data storage. And over 500 other meanings, 168 of which are in Information Technology! It also is used to describe automobiles with both a gasoline engine and an electric motor, each of which can propel it. Go to 2:10 on this link for a joke about hybrids that cracked me up.
So, for me, a better word to describe the appropriate use of on-premise technology and off-site Cloud platform, is “two-tier”. An excellent example of a two-tier approach to data protection and restoration can be found here. It brings the best of both worlds together for faster backups that are not dependent on an internet connection to be successful. With it, restores can happen about 40-50x faster using this approach. Lastly, it continues to create durability into your infrastructure as a foundation for an excellent operationally efficient business continuity strategy.
