Safer storage for my files

Recently I have had trouble with an raid in my main computer. I haven’t gotten an definitive answer for what the faults are. I say faults since it’s the same problem with two identical disks. Both has a delayed write problem in windows, even through one is failing ten times as much as the other one.

This trouble has renewed my interest in better and safer storage solution.

As it looks now is that I’m going to end up with a solution based on zfs. And then share this storage via samba, nfs and so on.

What I still has to solve is backup, I would like an offsite solution.
