I run a zfs array on a home server. The server's off most of the time, so I don't have any fancy services running from it. When my phone gets low on space, I move my photos and videos across via plain old USB. Same when I reformat a machine: I gather all the files I want to keep into a single folder, then move it to the server. I used to run zfs with one redundant drive. I had a drive failure, bought a replacement drive, swapped it in, and had zero loss to my knowledge. I later read that drives tend to die around the same age, and doing a drive replacement is a very strenuous activity, so you shouldn't just have one redundant drive. So now I have two.
