BATCH SCRIPT

I am running win. server 2008 as a virtual machine. the machine is hosting the SQL database. The SQL backup is deposited on the virtual platform. I have created a mapped drive from the Base machine where I am able to manually copy the backup file to an external storage device. I want to create a script and schedule it to run to copy from the mapped drive to external device.

I tried to create the following

xcopy z:\backups\* f:\external\* /y/q/s
