Quite easy really. Once you have the usb connection validated (see earlier post), backing up is simply a matter of :
pilot-xfer -p usb: -b ~/my-new-palm-backup-dir
You can also do a local update (-u palm-backup-dir) or a sync (-s palm-backup-dir).
Further options are available with pilot-xfer --help
Now to have a look at J-Pilot, a GUI. (no, it’s not written in Java)
