Error when backing up with windows media player songs in backup drive.

[BadDayComing]

Hello.

I've got all my music in an external drive.
When i configured bakups i selected that same external drive as destination to back up to.

Now, i added the music from that drive to windows media player and now, when the computer backs up, i've got this error telling me some files were omitted (namely all the music) because they're on the same drive as the backup's destination.

I'm going to use WMP because it's already there (regardless of there being a million better choices of media players/managers) so don't bother suggesting otherwise.

My question is: is there any special folder i should avoid backing up so this error doesn't happen? (like the one that contains WMP database)

More info:
Event type: Warning
Source: Windows backup
Event ID: 4106

Thanks for your help =)

Edit: The backup's error window gave me a link to more information; it's actually the log file but it's in Spanish and while i'm not sure it would help, i'm sure it wouldn't hurt.

Copias de seguridad omitió la copia de seguridad de Z:\Musiquita\ porque no se encuentra en el destino de copia de seguridad.

Windows won't let you backup files on the destination disk to the destination disk. It ain't gonna happen. Change the location of your music files or the disk you're using for backup. It's not good to use a backup disk for anything else anyway. The disk itself becomes less reliable because a write fault could destroy your backup. What's the point of having a backup if you're not using it as a backup?
