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? =46irst 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? --john 2011/7/3 David Brown : > On 02/07/11 23:17, Simon Matthews wrote: >> >> I thought that I had read the TLER was not useful for mdraid, so tha= t >> enterprise drives were not really advised for mdraid.
