If vmsbackup is compiled with the remote tape option and the file name has the form system[.user]:/dev/??? vmsbackup will use the tape drive /dev/??? on the remote system system, via rsh(1), and rmt(8). The optional user portion of the pathname specifies the login name to use on the remote system. If it is not supplied, the current user's login name will be used. In all the cases, the user must have the appropriate permissions on the remote machine, in order to use this facility. The default is /dev/rmt8 (drive 0, raw mode, 1600 bpi). This must be a raw mode tape device.
