Ocarina's Carter George continued the conversation on backups, asking if the
conventional backup paradigm was obsolete, and if file copies could serve the
same purpose. As mentioned in our "What Is a Backup?" post, this is the same
question posed by EMC's Scott Waterhouse recently.
Putting Copies To The Test
George suggests a copy-based scenario: "Why not just move files that are
candidates for being backed up to a separate tier of storage, keeping them as
files in their native format, and organizing them in time coherent views?"
To determine whether this is truly a backup, let's apply our new rules to
determine when a copy becomes a backup:
A copy is, by definition, a copy of a set of data. This copy is not mentioned
as being protected or offline, which worries the IT admin in me. Could they
be overwritten or corrupted? Would they disappear along with the primary data... (more)
Much discussion in the cloud computing world has focused on a simple
question: Is a private cloud infrastructure worthy of the name? It's been
posed in many ways, with some going so far as claiming that there is no such
thing as a private cloud. Although discussions like these are all too common
in many areas, the question really amounts to little more than counting
angels dancing on pin heads. The key issue is whether private cloud-style
infrastructure can deliver real benefits like public clouds can.
First, let's set out some definitions:
The draft NIST definition, perhaps the ... (more)
As I discussed in my previous post, What Makes Cloud Storage Different from
Traditional SAN and NAS?, today's cloud storage is unique from the SAN and
NAS (and even CAS) that has gone before. Beyond the cost and flexibility
benefits inherent in public cloud computing resources of all sorts, cloud
storage is unique in its openness, programmability, and the possibilities it
opens for distribution and collaboration.
These compelling benefits, along with an explosion of cloud hype, have led
every company with a product even remotely "cloudy" to jump into the market.

In my last blog post, I pointed out the new laws in Massachusetts and Nevada
that require all personal data in transit to be encrypted. That post
generated lots of discussion, including thoughtful responses from Steve
Duplessie and Joseph Martins, and I urge you to read those as well.
Two key questions remain: What exactly do these laws demand and how will you
actually comply with them? Sure, encryption technology is widely available,
but actually implementing it has been a slow uphill climb for most IT
organizations. Let's examine the implications!
What the Law Requires
In my ye... (more)
As discussed yesterday, the incredible growth of storage capacity led to an
attitude that storage was too cheap to manage. Excess data capacity seemed
always to absorb any new demand. But the unchecked growth of data led to the
serious issues that storage managers face today: Difficulties in protecting
massive data sets, concerns about compliance and litigation, and storage
budgets that refuse to shrink.
Why isn't storage getting cheaper? This series of articles attempts to answer
Too Cheap to Manage Too Much to Manage Tiered Storage The Glass Floor Storage
