A Data Protection Reference Architecture – Part 1


This blog will have multiple parts.  I will introduce my view of a data protection reference architecture and the next few blog posts will talk to components of that architecture.

The other day  I had a very interesting conversation with a colleague of mine in Australia.  He was looking for a data protection reference architecture that he could use to speak to his customer.  As you can imagine having this conversation over the phone could pose to be a difficult challenge.  When the conversation began, my fear was he was looking for an ‘architecture’ diagram that included data protection appliances, backup servers, disk libraries, tape libraries and backup agents.  I quickly realized that this is an impossible conversation to have with him without knowing:

A)     the customer’s environment or challenges

B)      the customer’s business objectives

I find that most vendors don’t know A or B when speaking to a customer about their data protection ‘issues’, but they really should.  Having a more thoughtful conversation with customers in a consultative fashion is more relevant to customers in understanding their challenges and helping to align these challenges to the best possible solution.

I started my conversation with the diagram shown below (Figure 1).  A simple triangle divided horizontally into 4 segments and the middle two segments divided vertically in half.  Each segment represents different business objectives within a company.  As you go around the triangle, you can see that there are different technologies and different methodologies for attacking data protection challenges, which is why there is no longer a “one size fits all” approach when it comes to protecting data today. Let’s face it; the two most important commodities in backup are time and capacity.  One of the primary drivers behind the type of protection that is used is the Recovery Point Objective or RPO.  Different technologies provide different RPOs and each has a different price point as well as there are different processes that can be applied to attach RPOs.

Road to 'Data' Recovery – 12 Steps


Hi, my name is Steve and I have a recovery problem.  Well, a data recovery problem that is.  So, I think it is about time that I apply the '12 steps' to help me with my data recovery problem.

Step 1 - It is time that I admit that I am powerless over my backup environment and my data protection world is unmanageable.

Step 2 - I have come to believe that there is a Technology greater that I that can help me restore (my sanity).

Step 3 - I have made a decision to put our company's data and the process of recovery into the hands of a true data protection specialist.

Step 4 - I have helped to create a classified inventory of our company's data.

Step 5 - I will admit to our CEO that I have failed at 63% of my recovery attempts costing the business $MMs.

Step 6 - I am prepared to have the new data protection administrator remove all of my defective technologies.

Step 7 - I will humbly ask 'him' to remove all of my failed processes.

Step 8 - I must make a list of all the people I have been unable to recover data for and be willing to try to restore their lost information.

Step 9 - I must make amends to all the people I have been unable to recover data for.

Step 10 - I must continue to take an inventory of all the tapes we have and promptly convert them to a newer technology to enable faster recovery.

Step 11 - I will seek out best of bread technology, parnters and vendors to improve our company's capabilities for daily operational recovery.

Step 12 - Having had this spiritual awakening as a result of these steps, I will carry this message to all IT administrators who are challenged with data recovery issues.

I believe that by following these 12 steps, I will have put our company back on... the Road to 'Data' Recovery.

Lean Six Sigma Your Backups


Last week I took a course offered by EMC entitled ‘Lean Six Sigma' - Yellow Belt. This is a training course that is used to help ‘solve problems' in a given process, typically work related. When I think about where the biggest problem is in IT its in the Backup arena so I thought, what a better place to test it.

There are two components to Lean Six Sigma. Lean or Leaning a process is about removing excess from a process to make it more efficient. For backup, moving as much data out of the backup stream as possible would increase backup efficiency.  Deleting unnecessary data or archiving static data in the production storage can cut down on as much as 50% of the data in the backup, ‘leaning' the process.

Next, when looking at Six Sigma, we learned about the DMAIC process. That is:

  • Define - Business case, scope, problem statement, goals
  • Measure - Process flow, run charts, Pareto charts
  • Analyze - Cause / Effect, waste identification
  • Improve - Waste removal, improve plan, control charts
  • Control - Monitor to prevent repeat failure, control charts, control plan

First, as I was thinking about this, I kept coming to the measure phase. If you don't currently measure your backup process, unless of course only when there is a recovery failure, then perhaps its time to invest in a tool to help measure the current process.  This measurement will allow you to identify current problems, serving as a benchmark against wich you can measure the success of your 'leaning'.  So, if we apply the steps in the DMAIC process to your typical backup environment, here is what it may look like.

Road to Recovery


Our domain, Backup & Beyond was the tagline for Avamar Technologies, a company EMC acquired in November of 2006.  This tagline was very fitting from a data protection standpoint because Avamar utilized a traditional client / server architecture to protect data but with a twist.  Avamar utilizes a more intelligent client side agent that provides source based, variable block deduplication to enable the most efficient backups available in the market for more than 80% of a data centers data.  Avamar also leverages this same technology to replicate this data between disk based backup targets there by dramatically reducing the reliance on tape.  This new technology, that has enabled new processes is taking backup beyond.

The title of our blog, Road to Recovery - well, like every good title it is a play on words and trust me, as with every title it took us a while to come up with it.  That said, the industry has been talking about the fact that backup is really about recovery.  The same can be said for other data protection tools.  This is why our goal is to talk about methodologies (technologies and processes) that help you to recover data.  When IT professionals are polled, they often say that data protection (backup) is still the number one issue they have in the data center.  We say it is time to stepup and admit it and start the 'Road to Recovery' when it comes to your data protection environment.

Let us know what your challengs are, we are here for you, your support system and we welcome you comments and questions.
