I had to move a bunch of files over from macOS to my Framework laptop, including a bunch of node stuff that just wasn’t copying via the standard file browser in Fedora 37. This means I turned to rsync which will just work to copy any amount of files, and can resume itself.

Where is my Synology?

Step one was to find my Synology which was already mounted in the file browser via SMB. In Fedora external mounts like this will be found at /run/user/1000/gvfs/<mounted drive>.

Then you run rsync -urv /run/user/1000/gvfs/<mounted drive>/<folder to copy> ~/<destination folder> and let rsync do it’s magic.
