I am working on a scheduled task back up. I am

I am working on a scheduled task back up. I am using a MS Batch file to get it running. It will run fine but it fails giving me a 0x4 error.

The script is as follows:

xcopy n: est_backup*n: est_backup%date:~0,3* /Y /Q /S

I am attempting to point it to the drive where the file is located, get it to back up said file on that drive and it will run but automatically fail. The 0x4 error means that it cannot find the file but I have it saved right there on that drive with that drive letter.

What am I doing wrong?
