Many people do not need a hypervisor, or the additional isolation between programs since docker isolation is good enough. Proxmox also makes backing up data easier, but if you know how to stop containers, incrementally backup your data with Restic, then restarting your containers then you’ll be fine

This is one rabbit hole you've got yourself into, but wait there is more... Here enters: BACKUP STRATEGY You start thinking, and say hmmm.. I use proxmox naturally PBR should be good, but then you look at the documentation and be like, I need something simple maybe rsync. Then rsync doesn't do increments like let's say Kopia or Veeam... Then location, S3 bucket or Hetzner Storage box for off-site backup, maybe use some external hard drives that you forgot about... Then you catch yourself thinking what if this backup fails which backup is quicker to recover and also, how do I test the snapshots, when do I test them?! Oh man... And at the end, after you setup everything you start thinking... Maybe that google photos or drive isn't that bad for 20$ a month But no fun in that, so enjoy!
