Using UNC name for local drives in Batch files

Question

I need to do copies/backups between a Windows XP computer, a Win 7 computer and several NAS drives using Batch files. I need to avoid using plain drive letters as there is a possibility a Batch file for one computer may be executed on the wrong computer and overwrite the wrong local drive.

xxcopy  "\\127.0.0.1\G$\sample\"    "\\NAS1\Volume_1\sample\"   

will copy from the current machines G: drive to the NAS, but I want to be able to do

xxcopy  "\\Computer1\G$\sample\"    "\\NAS1\Volume_1\sample\"   

or even

xxcopy  "\\Computer1\G$\sample\"   "\\Computer2\G$\sample.copy\"

but when I use the computer name - I get 'Remote source not accessible'

Answer 1

You can use the %Computername% variable for the local computer.

xxcopy  "\\%Computername%\G$\sample\"    "\\NAS1\Volume_1\sample\"   

If you extract the %Computername% variables from all your machines then you can hard code them into your backups scripts.
