How can I be a happy chap in IT? Let me tell you about it:

* The RAID is a backup fallacy: RAID is for redundancy, NOT backups! (Seriously, people!)

* Neglecting backups: Data loss is tragic. Back up your precious files.

* Blind faith in backups: Test them! Know how long it takes to restore. Otherwise get ready for Schrödinger's backup 😉

I would add:

Hardware RAID is a single point of failure.

@nixCraft Hope it's not bad form for me to say I'm very happy with rsync.net/. I backup there from macOS, Windows, and Linux, and set my custom zfs snapshot cadence, and have successfully restored from them. No issues and I've been with them for years.

@nixCraft noone wants backup, everyone wants restore.

@nixCraft In my experience, the RAID-fallacy has been replaced by the cloud-fallacy in most organisations these days.

@nixCraft I got to test my backups just this week. I was working on some scripts to try to provoke a ZFS bug and was developing on the target host (a Raspberry Pi.) I had put my development directory in the pool and without much forethought, destroyed the pool. 😬 Luckily for me, part of the testing involved sending the pool to another host so I just recovered the project from the backup host. 😀
