How to prevent an IT tsunami

"Bank of America has become the poster child for how not to transport data.

Over the weekend, the Charlotte, N.C.-based financial institution announced it had lost backup tapes containing the personal and financial information of 1.2 million customers.
The missing tapes contained U.S. federal government charge account information -- and the personal information of federal employees and U.S. senators."
One cannot be but surprised that certain things can happen, especially when it comes to Bank of America, but it is easier than one can think...
People tend to never do anything until they're burned. Before having a true disaster, an IT tsunami, usually no one thinks it is worth spending the money to protect themselves.
But IT IS.
That is why choosing the right company to help with the Disk backup proves very often to be the right insurance...
It is enough it happens once and you understand how much for the rest of your working life.
Besides, if you chose the right company, when the worst happens, they can help you to restore your data.
The newest and probably best system to store safely data is RAID (redundant array of independent disks, originally redundant array of inexpensive disks) which uses more than one disk drive to divide and replicate data among them.
The drives are said to be in a RAID array, the new way to be accessed by the operating system as one single drive.
Originally they began with five Raid levels (standard schemes) now you can have up to six.
The Raid systems can be classified as Failure-resistant (systems that protect against loss of data due to drive failure), Failure-tolerant (systems that protect against loss of data access due to failure of any single component) and Disaster-tolerant.
That gives extra protection against loss of data, and better help in restoring lost data.
The distribution of data can also be done with software instead of multiple hardware. Of course to achieve the desired protection against physical drive failure, a RAID must be properly set up and maintained by an experienced operator.
