Can’t say enough good things about ProxMox. Pair it with Proxmox Backup Server and you’re golden. If you/an upgrade breaks something, just restore that LXC/VM from backup. Can’t pay enough for that kind of peace of mind. And PBS will take care of deduplication, retention and verification.

Currently running a few U6s. No real motivation to upgrade to U7s.
