My most critical data is only ~2-3TB, including backups of all my documents and family photos, so I have a 4TB ssd attached which the pi also boots from. I have ~40TB of other Linux isos that have 2-drive redundancy, but no backups. If I lose those, i can always redownload.
For the delay, I just reduce how often it checks for new files instead of instantaneously.
Agreed. I have it configured on a delay and with multiple file versions. I also have another pi running rsnapshot (rsync tool).
Syncthing to a pi at my parents place.
Oh no! Anyway
The shortest distance between Tesla and your house is a full circle around the country.
Funny you mention it. This is exactly what I do. Don’t use the relay servers for syncthing, just my tailnet for device to device networking.
