John, Sometimes we have to think outside of the nine dots :)

This maybe necessary for media like tape, but does it really apply to disk. The data is periodically being checked for errors all the time, and if a chunk actually fails it can be replaced and rebuilt. SATA is a paradigm shift. > Also, all archival data should have at least three copies made. Perhaps another way to say this is the data must still exist after two concurrent media failures. In HDS we call that RAID-6 (so do STK). > The media should be stored in house, and at separate off-site locations > (preferably well separated locations, say CA, KS, and NY, maybe even > internationally!). International is not a new thing, and the bandwidth to do is becoming more accessible every day. I know of two Banks that run international Remote Copy - one from Singapore to Hong Kong, and one HK to Singapore. > You'd use the in-house copy to recreate all other > copies, with the offsite copies being sent back offsite.
