Help !

So many foolish statements made in this thread.
1)  backup your data to the same disk drive if you buy a big enough disk, NAS or anything else. Sorry but this is idiotic. If your NAS fails, everything is gone. Even if you use something like a Drobo box or a RAID setup, always backup this data to another external disk. I worked with multi-million $$$ disk subsystems using RAID and you always backup to another disk. 
2) legally, you can’t copy something, keep the copy, and then give the original away or sell it. You paid for 1 cd. You copy it and the sell/give the original, now you have 2 copies.

I agree that Linux is the way to go ONLY if you understand it. Very few people can get into Linux to do anything like assign a disk and create a backup routine. How about using FSCK to look at trouble areas? I ran million $$$ Linux database servers and it's the preferred choice for enterprise applications. As for the common Joe user, Linux is not there yet. If you buy a 3rd party music server, who are you going to take it to to locally to get it worked on? Also, if all you want to do is read bits off a disk/SSD, a Mac is all you need running Roon. Also most music servers want you to use USB which is a flawed interface.
