Hi all,
I have a question about how to distribute vtapes on multiple non-raid
disks: is there a best way to reduce the damages in case of loosing
one disk?
In a system where no raid is implemented, what is the best strategy
to manage the vtapes?
What I mean is:
Is this configuration:
* disk1: day01 day07 day13 day19 day25 day31
* disk2: day02 day08 day14 day20 day26 day32
* disk3: day03 day09 day15 day21 day27
* disk4: day04 day10 day16 day22 day28
* disk5: day05 day11 day17 day23 day29
* disk6: day06 day12 day18 day24 day30
if you lose a disk, you might lose all full of a DLE, you will not be
able to restore it.
better than this one(?):
* disk1: day01 day02 day03 day04 day05 day06
* disk2: day07 day08 day09 day10 day11 day12
* disk3: day13 day14 day15 day16 day17 day18
* disk4: day19 day20 day21 day22 day23 day24
* disk5: day25 day26 day27 day28 day29 day30
* disk6: day31 day32
if you lose a disk, you lose 6 days of backup, but you can restore an
old copy of each dles.
