Seconding this. On my unRAID host, I run a docker container called “Vorta” that uses Borg as its backend mechanism to backup to my SynologyNAS over NFS. Then on my Syno, run two backup jobs using HyperBackup, one goes to my cousin’s NAS connected via a Site-to-Site OpenVPN connection on our edge devices (Ubiquity Unifi Security Gateway Pro <-> UDM Pro), the other goes to Backblaze B2 Cloud Storage.

OP, let me know if you need any assistance setting something like this up. Gotta share the knowledge over here on Lemmy that we’re still used to searching evil Reddit for.

Most likely Hyper Backup & Hyper Vault, two applications built into Synology’s DSM software that runs on their NAS devices.

This is fantastic for us homelabbers. Now I can pick up some insanely powerful ones years from now for dirt cheap!
