Thanks Dave but my backup scheme has two NAS drives but no RAID arrays. It is not slick but I had a problem once with our UK data center where we had a RAID 5 array but still lost everything because it was not a drive problem but a controller problem that wrote garbage to the disks. Fortunately we did a tape backup every night so only a partial day had to be restored from paper. In our US data center we also had a RAID 5 array and almost lost everything because we had one drive go down and the afternoon after the defective drive was replaced and the array rebuilt, a second drive failed. Very unusual but if the second drive failed a day earlier, we would have lost everything.
Another advantage of manually refreshing separate NAS drives is if you get a virus, it will not automatically propagate to the other drives in an array. Slow and clumsy but safe.
I prefer to have my most often used music on an internal SSD in the NUC to minimize latency. There are times when I use external storage on Daphile either from the NAS drive, a USB flash drive or a USB hard drive and it works well. I also have a copy on the NAS storage and a portable USB drive I can take on location. Beyond Compare works very well on a local network and I have not tried it with cloud storage. My offsite storage is a USB drive that I refresh from local backup data on the in house NAS and then bring it to a safe deposit box at the bank. Not likely to get hacked. Since moving I have not gotten a new safe deposit box so I am re-thinking that scheme.
Understand the problem with striped drives for RAID, I use disk mirroring (RAID 1) on my NAS, large drives are cheap, and it is an automatic backup of all the data. I have not run into latency issues personally, but I just upgraded to Fios Gigabit from Verizon and have hard wired connections to my endpoint. Pulling data off a network drive is pretty fast.
