Does anyone have experience using this to sync between a Windows PC and a Mac? I've tried using OneDrive and it's pretty bad. I basically keep it disabled until I remember, "hey I haven't synced in a while, turn it on until complete, then turn off again."
It's backup, not sync. Your basic consumer choices for cloud-based sync are OneDrive, Google Drive, or DropBox. I prefer Google Drive now that I can keep all my files in the cloud and download/cache on demand, rather than keep it synced -- this way I get a usable 2TB disk rather than being limited to my laptop's 256GB storage. Google announced a new unified app yesterday actually: https://arstechnica.com/gadgets/2021…
I do however want a remote copy of only current local files, which is a kind of sync. Then be able to make a local copy of the current remote files in a device/directory of my choice. A command-line tool to start the sync operation is fine, especially if it can run incrementally/resume.
