When I try to create a backup in my network folder, I am getting this error
Error
RPC ERROR: Filesystem I/O Error mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)
figured it out. for context i use windows. i trouble shooted everything i could possibly think of, what ended up working was different than the start9 instructions for windows network folder backup. the instructions tell you to use the entire name of the path for the path name (with // and everything else), what ended up working though was just the literal name of the folder (what your instructions are for mac and linux)
