Ok. Assuming that's the route I take, and adopt your maxim of backing that up to a large USB disc, can I automate that? I don't mind copying stuff to a NAS but then don't want to have to go to the trouble of copying stuff to a USB disc as well. The reason I want it to be automatic is that I know things will be overlooked if they're not.
In asking the question about automating the task of a backup, I don't mean running a backup for example, overnight. Instead I was wondering if it was possible to automatically copy anything new from the RAID to the USB device as it's written to the RAID.
For a device to house the discs, I'm considering one of these - http://www.ebuyer.com/722189-hpe-proliant-gen8-g1610t-819185-421-4gb-ram-mic... and using Debian as the OS.
Assuming that, to start, I use my existing discs, but later expand to 2 * 2TB drives, I assume that I can use all 4 drives but have each pair mirror one another. So that I have the 1TB discs mirror each other and the 2TB similarly mirror each other. Can I do that using RAID?
Next question concerns the filing system. Somebody has suggested to me that I should be considering zfs. I've no experience of that so is that something I should definitely do or possibly consider, or not bother with?
