In Part I of this blog entry, I talked about maximizing your data protection budget by considering consolidation and looking at disk-to-disk (D2D) or disk-to-disk-to-tape (D2D2T) solutions. In this article, we’ll look at deduplication and some budget savers versus budget busters.
Enter deduplication. When you start deduplicating data it can drastically decrease the budget requirement for disk due to reduced space needed. It reduces storage by eliminating redundant data. One unique instance of the data is retained, and redundant data is replaced with a pointer to the original unique data. So, less space, less money.
Further savings with disk is recognized with significantly faster recovery times. Remember cassette tapes and how cool it was when CDs entered the market?
If you wanted to hear song number three on your tape, you needed to hit
fast-forward and wait. When CDs showed up, you could enter any random track and get your song near-instantaneously. I don’t know any IT managers who don’t want to deliver this functionality for data restore to their teams. So, not only are you buying less disk with deduplication, but you speed up recovery producing further cost-savings.
Another disk benefit is reliability. There is no argument that disk is more reliable than tape. Anyone who uses tape will tell you it’s fragile. Humidity, temperature, number of uses will all negatively impact your chance of getting your data back. Are you confident you have proper guidelines regarding tape storage at your organization? What happens if the person whose job it is to swap tapes and take them off-site, leaves them in the car to run a quick errand, in the middle of summer, and you happen to be located in Arizona? Basically that tape is not usable. But you won’t know until you have to restore something. That’s an extreme example and unlikely that any IT manager is advising his team to manage their tapes in this fashion, but I’m sure you’ve heard of or experienced yourselves numerous accounts of data loss when recovering from tape.
I’m not saying you do away with tape backup. It’s a good solution for long-term storage, but it certainly is not cost-effective when it comes to reliable, fast recovery. If you can get the correct business unit managers supporting a disk-based purchase initiative, you can easily show tremendous cost-savings associated with productivity and reliability to your CFO.
I’ll leave you with one last cost-savings tip, choose one vendor with a suite of products to support your data protection requirements. You don’t want multiple finger-pointing vendors when you have questions, and it makes life much easier for your team to learn and stay trained on the applications.
Consider a couple of things when evaluating vendors: 1) how easy are the solutions to administer, 2) how responsive is support. I had an experience with a customer who was using a competitive product. While I was on site, he called the other vendor’s support to help resolve some issues. Meanwhile, he allowed us to do a proof of concept with our product. We installed, configured, and completed a backup before our competitor’s support team had even answered the customer’s call.
Make sure you understand every aspect of a vendor’s support program before you enter into a contract. This is overlooked far too often, in my experience, until you actually need support. This oversight can unexpectedly impact your budget and increase the overall cost of the product.
So here’s the thing: it’s not difficult to find cost savings when it comes to adequate and proper data protection. Just remember…
