> Doing some quick assumptions (all RAID10, HDs 50% full, tape compression
50%) and math, that's about 23TB of data to be backed up onto 690 DAT tapes.
At about 3MB/second transfer rates and tape swapping, that's about 3 months
to do one backup. And I have no idea what you do if you need a restore at
day 70 of the backup...
Btw, the database size is quite tiny compared to the total disk space. They
just have that many disks for having more spindles to get the IOPS
required...
