Re: Recommended sw raid setup

[John Obaterspok <john.obaterspok@gmail.com>]

Hi all,

Thanks for all good answers!

Today I got all my family data spread in hux-flux between medicenter,
laptops, external disks - no redundancy what so ever.
I would really like to have a backup solution too, but how do I backup
6 TB in a fasion that makes me do it more than the first 5 times?

First I thought about using btrfs with snapshots on the RAID5 as a
substitute for backups, but that might not be worth it in the sense
that it doesn't give me much more safety?
