When did a personal Storage Area Network (SAN) device become a “Cloud”, much less a “Personal Cloud?”
The Cloud concept originally was that instead of having dedicated physical devices upon which to store all of your “stuff” (professionally, that would be databases, application code, software, files, et.al.), you would have potentially an Application Service Provider (ASP or hosting company) give you <x> amount of storage for <y> price and you wouldn’t worry about how much physical hardware went into the result. You pay to store.
Because it was a “cloud” you could “see” your storage from a number of different places and thus it would be more accessible.
Then came “Private Clouds” — the concept of actually owning the storage hardware and bringing it inside of your firewall so it was more secure and only internally visible, and perhaps you could cut out the added cost of a provider’s overhead.
In this example, YuuWaa Software is technically a cloud backup solution (for which you would normally pay “x” for “y” price to store your stuff.) But once you point the software back to a single external hard drive sitting in your closet, prone to whatever failures arise, it is not “cloud-like” in any way. This is akin to making “a mountain out of a mole-hill.” It’s just a remote backup. Unless you have a backup, for your backup system, it probably isn’t as reliable as you’d think.
Clouds can be beautiful and puffy, or they can contain unforeseen dangers. So, know your “Clouds.”
