Drop to DOS and do what you would like the backup to do. Take a note of all the commands you use.
Make a new text file, enter the commands on seperate lines. Give the text file a .bat extension.
Whenever you double click the new batch file it will run the commands you specified.
You can also play around with archiving files if you have a DOS based archiver (pkzip etc)
You will have to specify remote drives in the format //remote machine name/drive letter/ unless you have mapped drive letters (What OS you are using can affect this)
