Syncthing - No introduction needed. Couldn't live without it.
Healthchecks.io (you can self host this) - Dead man's switch monitoring for all my automation. Most of my automated scripts hit up a Healthchecks endpoint when they run, and if they fail to hit the endpoint on a regular schedule I get notified. Mandatory for my anxiety.
It depends on what your workflow/usecase for putting documents on the drive currently is. Syncthing is usually intended to be put on two separate devices, and then a folder on each device gets synchronized - meaning you have a folder of your documents on each device. Is there any reason not to just mount the network drive's folder and drag the documents in that way?
Yeah, that's how I do it now. I just mount the network drive on each PC and they can all access the same files. I'm just wondering if there's a usecase that syncthing has that my workflow doesn't that I just can't think of because I haven't used it.
Yeah I wouldn't bother. It intends for you to have a duplicate copy on every device, which is probably not what you want. Syncthing is really good for things like synchronizing notes, calendars, password databases, music, etc to your devices. Things that you want to access in both places, but that are usually disconnected from each other from time to time.
