As long as you’re not relying on RAID as your backup. Don’t know why so many people struggle with understanding, RAID is not a backup. It’s a solution to ensure uptime in the face of a lost disk. I would guess most selfhosters shouldn’t be concerned with uptime. Use Borg or restic. Or if you are going to use zfs or btrfs then have a completely separate drive or pool where snapshots are stored.
Do you need to serve an actual public like a website does? If not then you shouldn’t be exposing any fucking services except for wireguard for you and your handful of users.
