Thin Provisioning is a fairly well known concept in the storage marketplace; provisioning a logical volume larger than the physical capacity actually accessible by the application or server (http://en.wikipedia.org/wiki/Thin_provisioning ).  Most storage array vendors offer thin provisioning on some or all their systems.  Many charge a premium for this feature as the gains in efficiency, CapEx and TCO are obvious.

However, for data protection purposes (mirrors, snapshots, and remote replica volumes) few give this technology consideration.  If your primary storage array does not have thin provisioning (or you did not pay for the feature), any underutilized capacity will be duplicated onto your data protection volumes.  This “duplication of waste” results in higher costs from a CapEx and OpEx perspective, resulting in questionable TCO of any data protection solution.

I’m often amazed by the things I learn talking to customers.  This technology space eventually comes down to money   –  making it, saving it or wasting it.  One example of this last aspect, wasting it, is something I learned about from talking to a customer recently.

FalconStor has been developing data protection solutions for many years.  We’ve also had remote replication capabilities for many years.  Some of you may be aware of the unique nature of FalconStor remote replication.  However, for anyone who is not I’d like to put some perspective into how, and why, FalconStor remote replication is the best in the industry.

I saw this television commercial recently, by CarMax, called ‘Doors’; http://www.carmax.com/enus/why-carmax-commercials/default.html
So what’s the relation to data protection?  Most storage hardware, and even backup software, vendors offer many different functions, or types, of data protection; disk mirror volumes, point-in-time snapshots, remote replication, application-specific protection and management tools.  Each of these functions is considered a ‘product’ and sold accordingly.

With 2011 around the corner and new budgets being built, IT is looking at how to effectively deal with the rising amount of data that needs to be effectively stored and in the event of a disaster, available for quickly recovery. In my earlier blog (http://tinyurl.com/2atf4h6), I examined the pressures faced by IT and provided two reasons why disk-based data protection is becoming immensely popular in the data center specifically around how it eliminates the backup window and how companies may still create tape backups using continuous data protection (CDP).
