I’ve only just realised this is an active community (thanks Sept25 Community Highlights) and am very excited to see what you all are up to and interested in. As a brief intro to my setup: https://spsoul.blog/what-i-self-host-and-why/
The one thing I haven’t quite worked out is backups. I know all about 3-2-1, but that’s a lot to setup for a little free homelab like mine. All I’m interested in is having a daily or weekly backup just in case my hard drive gives out . I don’t necessarily want to setup an entire RAID right now or pay another company to handle it, unless it’s relatively painless. What’s the simplest setup you’d recommend for a novice like me?
If you use btrfs (nice for simple ad-hoc raid1 setups) then https://github.com/digint/btrbk is a very nice tool to automate snapshots and backups over ssh.
You can also improvise a setup with an external usb drive that you only connect once a week or so to do longer term backups. This isn’t exactly an off-site backup but somewhat similar if you store that drive away from the servers.
