The Better Dedupe Series – Implementation: inline or post process

| By: (135)

Deduplication can be implemented in a number of different ways depending on the needs of the technology provider. There are trade-offs in each and they have the potential to impact cost and performance.  Let’s explore them: Post Process – With post-process deduplication, new data is first stored on a storage device and then analyzed for duplication at a later time.   The benefit is that there is no need to wait…

Moving to the Cloud Seems Like a Good Idea, Taking Everything You Have Does Not

| By: (135)

Moving to the cloud is cool. Cloud storage is a hot technology for good reason – it can save you money! It seems fairly simple, consume and pay for only what you need. Cloud storage saves you the cost of pre-purchasing storage in anticipation of your needs and the associated operating costs for space, staffing and operating that storage. Most organizations are trying to reduce total storage costs while facing…

Not All Dedupe is Created Equal! Is there “A Better Dedupe”?

| By: (135)

It’s sometimes difficult to remember that a name or phrase that becomes generic doesn’t always represent the same level of quality.  For example, Coke became the generic phrase for cola soft drinks even though there were many brands cola soft drinks, often not nearly as well known or liked.  Similarly Kleenex became a generic phrase for facial tissue even though there are literally dozens of other brands of varying quality…

Dedupe isn’t always “dedupe” And Dedupe Everywhere isn’t always “everywhere”

| By: (135)

In my last two posts, I explored why deduplication approaches vary widely and dedupe everywhere sometimes isn’t really “everywhere”.  I hope I was successful in describing that the names may be the same in dedupe and dedupe everywhere, but what is delivered may be very different.  Although the approaches in deduplication vary, they are based on the ability to effectively address the key performance issues that have been, until now,…

“Dedupe Everywhere” isn’t always dedupe “everywhere”

| By: (135)

Dedupe is a hot topic and the differences between dedupe implementations was the topic of my previous post Now there continues to be differences in vendor offerings and marketing plays a role in defining who does what and how they describe it.  “Dedupe Everywhere” has been a phrase a few are beginning to use so I wanted to provide some clarity on the use case of dedupe everywhere and what…

Dedupe isn’t always dedupe

| By: (135)

Data optimization has come under much scrutiny lately because it is a hot topic. As we are now beginning to think “outside of the box” on uses of data optimization, it might be useful to understand that dedupe isn’t always the same! For example, some of the early uses of dedupe were in single instance approaches that were at the file level. So, if an entire file was not exactly…

Why Dedupe Everywhere? Ask Willy Sutton…

| By: (135)

In my previous post, I positioned deduplication as evolving to an “out of the box” approach that will deliver broader and more effective savings in dollars as well as space and resources. Now you may be asking yourself, with dedupe firmly entrenched in the backup realm, why do we need to dedupe anywhere else? Good question, let’s explore some of these answers.

Dedupe “Comes Out of the Box”

| By: (135)

Dedupe as we have known it is rapidly evolving and we need to think about it differently! Until recently a dedupe box or appliance was the status quo. It was a specialized device that was used, for the most part, in a data backup operation. It was an appliance that had its own separate storage, operating system, specialized software and in some cases, special hardware. As with many new technologies,…
