When rsync'ing over SSH to a remote system, who does the remote system think I am? I would have expected that as I rsync'd to email@example.com, and then typed in user's password for that machine, I would look like, and have the privileges of, user on that machine, just as if I had logged in over SSH as user.
I have a file server machine running Mint 18 with some Tbyte disks that I use as a backup/archive, and rsync to periodically from my Mint desktop. In order to rescue files from my son's viralised win10 laptop, I started it from a Mint stick and attempted to rsync files to the server, but it failed with a write premissions error.
Did it think I was user, or does my identity from the client machine contaminate things at all? I didn't attempt to troubleshoot, but simply used a USB HD instead. Before I do try to understand it (for next time) what should I expect? What should I have done?
