How does level of RAID affect it? Raid can only take care of a certain level of failiure RAID 5 (striped set with parity) will fail when two failures happen(two disks die or in this case tapes) And so on, but they will all fail at a certain level. For NAMAS and FDA standards they usually want a paper copy, in a fire proof safe guarded by the us military! (slight over exaggeration but not far off!) A customer had all there records on floppies and tapes for the past five years (real time data capture) The inspectors came in and failed them because there was not a 'permenant copy' Th ecompany had to buy a lot of extra gear and employ quite a few people to 'print out' the data. It took them five more years to do this! All digital storage has limitations (mind you so does all storage!) People put tom much faith in error correction and don't have enough backups. How valuable is the data. Vogon a data retreival company have a saying about securing data that is in a way also true of storing data. Is your data worth more then the disk drive? If yes then to completely erase the data 'melt it in a furnace' If not whats the problem? Is your data (pictures) worth more to you then the cost of multiple types of storage media and multiple Storage places? If not whats the problem? Alan
