What are the advantages of raid10 over zfs raidz2? It requires more disk space per usable space as soon as you have more than 4 disks, it doesn’t have zfs’s automatic checksum-based error correction, and is less resilient, in general, against multiple disk failures. In the worst case, two lost disks can mean the loss of the whole pack, whereas raidz2 can tolerate the loss of any 2 disks. Plus, with raid you still need an additional volume manager and filesystem.
Yes. I use a G7 N36L as an offsite-backup server in my second apartment. Works great with NetBSD and zfs, using rsnapshot to make remote backups every night.
Since it is only active for an hour and a half each night, it is my only server to put the disks into powersave mode the rest of the time. Computing eprformance is so low that I don’t even run a folding@home client. It usually cannot finish any work package before the deadline.
What’s your problem with DAVx^5? It’s completely and permanently free and fully-featured on f-droid. Only the PlayStore version costs money. The authors don’t want to make money, but motivate you to move away from Google infrastructure.
If you only need address/phone number sync, then nextcloud is probably overkill, but I use it, and it works great. Also for calendar sync and file storage.

I use the names of chemical elements, but with two twists: I assign them in the order in which they appear in the song “The Elements” by Tom Lehrer, and I use the German names. So I have (or had), among others, Wasserstoff, Sauerstoff, Stickstoff, etc …
