I‘ve got 2 Machines with Proxmox on both installed. One hosts my data and media and runs Services like Jellyfin, NAS,… The other one is a Mini-PC that hosts my Services like Adguard, Home Assistant,…

Whats the best way to Backup the data and configs of those 2 machines? Installing Proxmox Backup Server on each and store the Backups on a seperate HDD? Or would it be better if a move all the services to a single machine and use the second only for backups?

thank you!

Duplicati is at it's base just a fancy ui for backups as opposed to custom bash scripts.

It does support s3 storage, SFTP, ftp, and a bunch of other stuff so this might actually be on point for your off-site backup design.

Of course off-site backups are superior. If my home burns down I'm fked. I do use different hdds though, so at least there's some security isolation in that. Also if one of them breaks, the other one doesn't necessarily.
