I'm setting up a backup system on my local network that includes two Linux servers and a Proxmox server. I'm considering either deploying a Debian server with NFS shares or an S3 server for restic backups, or setting up an rsync server and using ZFS snapshots. Additionally, I plan to configure a Proxmox backup service on this server for Proxmox backups. Besides this setup, we're also planning to have offsite backups with BackBlaze using either restic or rclone. What would you recommend for the best backup solution?

Have you thought about Proxmox Backup Server? It could make things simpler since it's designed specifically for Proxmox environments. Just a thought!
Rsync combined with ZFS snapshots could be super efficient for local backups due to its speed and straightforward setup. Just make sure you also use offsite restic backups for added protection.
I've never really used ZFS snapshots, but I find restic or borg to be excellent for incremental backups. For Proxmox, using Proxmox Backup Server is key because otherwise, it does full backups every time which can waste time and space.
ZFS snapshots work independently of rsync, so you don't necessarily need rsync. I’d definitely recommend checking out Proxmox Backup Server, especially now that it supports more Linux setups. Just remember that Linux doesn’t have VSS, so be cautious with database and memory-mapped files!
Just a heads up, I've mostly worked with Btrfs instead of ZFS, but I feel that using a dedi-backup tool like restic offers better space savings than just file system snapshots.
I’m considering it, but I'm not quite familiar with backing up Linux systems to it.
