Hi,
I also think mirrored disks are better for this situation, I'm looking for redundancy, not a backup. For backup I will use Bacula.
I just got that my hardware are not that good as I imagined, and they are not that proper also, as they support only up to 4 HD's.
so by now I'm almost giving up on the NAS/SAN and have a local RAID with a good backup.
my main problem with the NAS is that I would store all the system in there, so if I got a problem with the NAS, ALL THE SYSTEMS WILL SHUT DOWN! and this makes me think a lot about this decision.
as I didn't find a professional solution case, I will give up temporarily on that.
thanks a ton for your reply!
Lucas.
