For data protection, you must first keep proper backups. RAID is for uptime, and for a homelab it’s not always needed. Backups first (external drive, cloud), then RAID.

Damn you’re lucky, that an awesome catch!

Very cool and neat setup. Nicely done!

And that is awesome!

I would go with Ubuntu Server. Anys OS will need maintenance. Alternatively, Proxmox if you’re into VMs.

As others said, Rclone and encrypt your data before sending. I wouldn’t trust no matter what the cloud provider says.

And another vote for Proxmox just in case. For containers, just spin up another Linux VM.

Most likely, the drive is damaged. there should be some local companies that do recovery. At least, it’s worth asking.

If you can still read it, I would start just manually copying the most important files one by one.

Well, as others said, ideally, follow the 3-2-1 backup rule: https://www.backblaze.com/blog/the-3-2-1-backup-strategy/. An external drive plus some other cloud storage like Backblaze Personal or iDrive.
