With time, it becomes increasingly difficult to keep up with the massive amounts of data we all store. Just stating 'backup often!' doesn't cut it when apparently the disk drives follow Moore's Law perfectly but backup solutions do not. I do not deny the need for backup, but how many people have a DLT IV 40/80 at home ? How many of you buy those DLT tapes, which are interestingly enough, MORE expensive byte-for-byte than the average harddisk (yes, you read that right). I have a DDS3 unit at home and a DVD burner. Still, keeping up with my 400GB raid array is very much work at best and near impossible at worst. I could put it all on 100 DVD+RWs, but to keep track of what has been backed up and where is just impossible. The tapes work better but I do full tape backup ehm, like, once or twice yearly. (yeah yeah I know...) One of the cheapest "backup" mediums right now are harddisks themselves (weird, isn't it?) so it stands to reason some people try to build something that is foolproof (at least against hardware failure) using that, just disks. How do you feel about this ? Note that this has nothing to do with business situations; where the neccessary DLT drive and or -libraries are just bought from the budget.
