If they are on Ethernet then use the FTP command in the command prompt. I use a commands.txt file that has the switches I want to use when I run my batch file.
For example
commands.txt has the following in it:
anon
prompt
lcd ROBOT_BACKUP
mget *.*
quit
Then I run a batch file with this line in it:
ftp -s:commands.txt XXX.XXX.XXX.XXX
Replace the "X"s with the IP address of the robot.
Make sure the batch file, commands.txt and a folder called ROBOT_BACKUP are all in the same folder. Then run the batch file.
Since I am not using the "bin" switch, the LS files will show up in ASCII instead of binary. add the "bin" switch if you want a binary backup.
Any other questions just ask.
