I didn't say it's a backup solution. It's the simplest form of keeping
data, and would have helped here.
We tend to do backup-to-disk and then disk-to-tape, which until now is
superior to just backup-to-tape. It speeds up backup and restore time,
even when "just" using simple 2TB SATA drives (in RAID-5 arrays). The
following disk-to-tape runs without any start/stop cycles of the tape
(mostly LTO4 now), leading to much longer tape and tape drive lifetimes
