It is - explicitly - designed to protect against catastrophic disk failure, not conflagration. And the backup job runs at 01:59:00, when all operators are happily asleep. The other advantage to this system is the cost. A (new) SCSI LTO-2 and 35 tapes runs US $2000 and up; the same four week's capacity is less than $400, maybe less than $300. Robert Huff
