It means that there are more disks than are strictly needed to store the data at full capacity. The redundant disk space is used to keep copies of the data should one of the "independent" (or "inexpensive") disks fail. See other entries on redundancy.

What you're looking for - is a RAID network. RAID stands for either redundant array (of) inexpensive disks or redundant array of independent disks) There is a comprehensive article on Wikipedia on how the system works.
RAID is the use of multiple disks and data distribution techniques to get better Resilience and/or Performance RAID stands for: Redundant Array of Inexpensive / Independent Disks

In its simplest form an Array is a series of hard disks conected to one desktop computer. More complex Arrays can be Redundant Array Inexpensive Disks or the Array could be Network Attached Storage depending on what the network requirements are.
"Redundant Array of Independent Disks"or you can also say"Redundant Array of Inexpensive Disks"RAID means you have your computers Hard drives linked to work in sync with each other,this could be used to back up data instantly or used to make your Hard drives all work as one big storage device.If you had two 500GB drives and put them in RAID you could make them act as one 1TB drive,the data would be split between the two drives.Redunant Array of Independant Disks.
