[Discuss] upgrading Android, and backing up texts

[John Blomfield]

I mount my Android tablet with "jmptfs". This program mounts mpt devices 
and comes with different names depending on the Linux distribution. I 
then backup using rsync. I have written a cron script to do this job on 
at regular times and remind me to plug in the device. To use this you 
will need to ensure that you have the Android adb suite of development 
software and fuse file system software installed. There are few 
statements you can un-comment to test when running on the command line.

# loop until device plugged in or quit

     NUM=${TEMP[0]}
     echo $NUM
     if [ "$NUM" != "$DEVICE" ] ; then
     # Drive is not plugged in
       /usr/bin/kdialog --title 'NO Device' --warningcontinuecancel 
'Please plug-in Device to USB\nand then Click Continue.\nClick Cancel to 
exit.';
       if [ $? = 0 ] ; then
         LOOP2=yes
         # do another loop to see if tablet has NOW been plugged in
         else
          exit 1

       else

Good luck John
