If it rains this weekend, don’t say I didn’t warn you!

Before I go any further, please allow me to clearly state that I am not intending to offend anyone nor be blasphemous or sacrilegious in any way. If you are easily offended, best not to read beyond this and perhaps give this Weekly View a miss.

“14 Make yourself an ark of gopher wood; make it an ark with compartments, and cover it inside and out with pitch. 15 This is how you shall make it: the length of the ark shall be three hundred cubits, its width fifty cubits, and its height thirty cubits. 16 Make an opening for daylight in the ark, and terminate it within a cubit of the top. Put the entrance to the ark in its side; make it with bottom, second, and third decks.

17 “For My part, I am about to bring the Flood — waters upon the earth — to destroy all flesh under the sky in which there is breath of life; everything on earth shall perish. 18 But I will establish My covenant with you, and you shall enter the ark, with your sons, your wife, and your sons’ wives. 19 And of all that lives, of all flesh, you shall take two of each into the ark to keep alive with you; they shall be male and female. 20 From birds of every kind, cattle of every kind, every kind of creeping thing on earth, two of each shall come to you to stay alive. 21 For your part, take of everything that is eaten and store it away, to serve as food for you and for them.” 22 Noah did so; just as God commanded him, so he did.

Chapter 7

1 Then the Lord said to Noah, “Go into the ark, with all your household, for you alone have I found righteous before Me in this generation. 2 Of every clean animal you shall take seven pairs, males and their mates, and of every animal that is not clean, two, a male and its mate; 3 of the birds of the sky also, seven pairs, male and female, to keep seed alive upon all the earth. 4 For in seven days’ time I will make it rain upon the earth, forty days and forty nights, and I will blot out from the earth all existence that I created.” 5 And Noah did just as the Lord commanded him. “

What’s this got to do with Data Storage & Protection?

Being a data guy, I’ve always been fascinated by the story of Noah. Think about it …first the Big Guy tells our man Noah to go ahead and build a massive storage device, and even goes so far as to instruct him to make it a three tier model instead of a flat tier! That’s right readers …bottom, second, and third decks could easily be solid state drive shelves, fibre channel drives, and SATA drives …or SAN, NAS, and archive if you prefer. And then the Big Guy actually TELLS Noah not only when to expect the outage, but also how long it will last! Oh that we could be so lucky when designing business continuity systems.

But what really interests me most about the whole shebang is that our man Noah had, in essence, a data problem. Yes, I know I’m probably skipping over the more obvious and probably bigger problem of the fact that the earth …and everyone Noah had ever known …was about to be destroyed by a massive flood but hang with me as I do have a point to make here.

The reason that Noah had a data problem is because the Big Guy tells Noah to grab seven pairs of every clean animal and two of every non clean animal …not to mention birds, seeds, creepy crawly type things …the lot. Now, I don’t know about you, but I’m thinking that being cooped up with that lot for forty days is going to get a bit smelly at the very least …and prolly a bit dangerous as the bigguns try to eat the littleuns and whatnot. But Noah has to grab ‘em and keep ‘em in the ark as everything he’s collected is going to be used to reproduce and repopulate the earth once it had dried out a bit. By the way, do you know what the first was our boy Noah did when he was able to leave the ark? Plants a vineyard, makes some wine, and gets royally pissed! Good man …and as some of you know, I’m a bit of a wine lover so I’ve always had a soft spot for Noah.

But I digress. I’ve often wondered if it wouldn’t have been a whole lot easier …and a lot less smelly …if the Big Guy had just said to Noah, ‘Look, just get out there and collect DNA swabs of everything and we’ll worry about how to reconstitute it all later.’

On the one hand, the Flood introduced the harshest version of data deduplication I have ever heard of …but also introduced us to the idea of the needs for good backups, a sturdy backup architecture, and stonking business continuity plan.

If only the Big Guy had let Noah use ZPR [Zero Page Reclamation] by grabbing DNA samples and sticking them in a yacht instead of having to round up the London Zoo and building a massive ark by hand.

Yet none of our customers have the pleasure of knowing when their next catastrophic event will be nor which of their systems will be affected. Some folks decide to go ahead and replicate everything from their production environments to a secondary or sometimes even tertiary datacentre ….challenge is, as data grows beyond a couple of terabytes to multiple petabytes that can get awfully expensive to maintain. Think herding two pairs of elephants from London to Manchester constantly as opposed to letting a couple of pairs of swallows fly back and forth on their own.

What to do?

Well, data deduplication of backup data can certainly lighten the load …the industry standard is a 20:1 ratio, or twenty copies of extraneous data we can get rid of for every one copy of ‘good’ data although I frequently see ratios that are much higher in the field.

Equally, given that 90% of data backed will be restored within six weeks …or not at all …it makes a lot of sense to consider backing up to a virtual tape library or to disk first, dedpuing as we go, and then clone whatever is left in six weeks to tape for long term storage.

Inevitably, however, as my dear old grandfather used to say …‘You gotta know where you are first if you want to know how to get somewhere.’ We need to understand what data we have, align it to the business importance placed on each data set as not all data is created equal, and how best to protect both the data long term and provide continuity for the business in the event of a catastrophic event or outage.

I can think of no better starting point than our Storage Assessment & Strategy Service which addresses all of these areas and gives our customers a well defined series of real recommendations which have demonstrable ROI, cost benefit, and minimised disruption to their production business.

Please feel free to contact me if you would like help in discussing your backup/recovery and business continuity strategies.

If only poor Noah had had access to the Sharpen Your Business tools from Computacenter!

Have a great weekend,
