I don’t think I’ve ever made a “clean upgrade” on Linux. I’ve done the opposite though, that is, bring an old install over to a new computer.

Always use /dev/disk/* (I use by-id) for RAID, as those links will stay constant even if a disk is renamed (for example, from sdb to sdd).

Ubuntu is just getting worse and worse. I was pretty happy running Ubuntu server for years after moving from Gentoo; I jag lost interest in spending time taking care for that server and wanted something easy.

I went to Debian half a year ago and it’s been great. Should’ve done it earlier.

ZFS is really nice. I started experimenting with it when it was being introduced to FreeBSD, around 2007-2008, but only truly started using it last year, for two NASes (on Linux).

It’s complex for a filesystem, but considering all it can do, that’s not surprising.

Helpful yes, but far from enough. It only helps in some scenarios (like accidental deletes, malware), but not in many others (filesystem corruption, multiple disks dying at once due to e.g. lightning, a bad PSU or a fire).

Offsite backup is a must for data you want to keep.

That’s in bytes. A modern NVMe drive can do about 7 GB/s (more than 10 for PCIe 5.0 drives). Even SATA could handle 5 Gbit/s, though barely.

Sorry for the nitpick, but you probably mean GB/s (or GiB/s, but I won’t go there). Gbps is gigabits per second, not gigabytes per second.
Since both are used in different contexts yet they differ by about a factor of 8, not confusing the two is useful.
