My father is a wedding photographer who produces around 50GB of data a week that needs backing up. He wants to guarantee the data he's backing up for at least a year.
Currently he has three off the shelf NAS boxes, each with two 1TB drives in a RAID 1 config. This seemed good, but the boxes were cheap and very unstable - the RAID arrays didn't work, and the two drives in each box were not identical when we pulled them to check. (One in each was full, the other was only 70-80% full - seemed that the RAID had broken at some point and the NAS was only saving to one disk.)
Having played with the three NAS boxes he has, they don't seem fit the purpose and we are not confident that they are able to store this data.
I have suggested that he buy a cheap computer with plenty of hard drive bays, and use Linux to set up the drives in RAID1, then set up Samba to copy files onto them.
Is this the best solution here? What would you do in the same situation? What's the easiest way to set up Linux in this way?
