They should be using as many RAID disk boxes as needed to hold what they need for current use, if not all their digital data, photos and text. The disks would be backed up off-line in an off site tape library. As newer tape capacities and technologies become available the major tape library vendors have tape migration capability. They simply change out some of the tape drives in the library for the newer technology and the software starts migrating their data from the older technology to the newer technology. How much capacity are we talking here? Take a look at StorageTek's L5500 tape library. Scalable to 960 tape drives and 132,000 tape slots. 13.2 PB storage with data transfers up to 65 TB per hour (yes to get that you gotta buy all 960 tape drives ;-) But seriously if you are in this class for quantity of data you are going to have more than one off site location in order to have two copies of your data at two different sites. A small operation can keep redundant copies of data with big RAID boxes and one off site tape library. Same principles apply to smaller tape libraries, even the smallest StorageTek library holds two tape drives and thus migration from one tape technology to another is highly automatic. That kind of capacity ought to keep Tim scanning those 8x10s for a long time ;-) Dan C wrote: > Assuming that an organization such as the New York Times stores it's > digital files on CDs, how many CDs would it accumulate in a year?
