Not as often as you might think. Hardware doesn’t fail like it used to.

Hardware also monitors itself reasonably well because the hosting providers use it.

It’s trivial to run a mirrored containers on two separate proxmox nodes because hosting providers use the same kind of stuff.

Offsite backups and replication? Also point and click and trivial with tools like Proxmox.

RAID is actually trivial to setup.l if you don’t compare it to doing it manually yourself from the command line. Again, tools like Proxmox make it point and click and 5 minutes of watching from YouTube.

If you want to find a solution our brain will find it. If we don’t we can find reasons not to.

Even if you do ZFS makes this pretty trivial as well.
