I’m particularly interested in low bandwidth solutions. My connection to the internet is pretty rough 20mbps down and 1mbps up with no option to upgrade.
That said, this isn’t limited to low bandwidth solutions.
I’m planning on redoing my entire setup soon to run on Kubernetes followed by expanding the scope of what my server does (Currently plex, a sftp server and local client backups). Before i do that i need a proper offsite backup solution.
I wish I had data that could fit on an SD card - I too don’t have off-site backups mostly due to expense. I have one other friend that is into homelabbing but for us to each backup on each other’s hardware would be ~$2k/each. Probably more on his end because I believe he’s using a consumer NAS without the room for additional expansion whereas I have a 25 bay commercial setup that’s only 1/5 populated at the moment
