I currently have my music library on a Netgear ReadyNAS NV+ drive.  I have about 1 TB of music.  I would like to be able to remotely backup this data but I am having a problem finding a service that will let me backup a network drive.  Has anyone been able to find a way to do this?

My first thought was rsync, I searched and found this:http://carlhutzler.com/blog/2008/10/31/readynas-rsync-backup-with-options/

I'm not a Readynas user, I have no specific knowledge with that hardware.

You might check out Mozy Pro if you want offsite backup for your NAS. 

If you don't mind the command line, then to backup/sync folders between computers I use "rsync".   
  rsync -avr /path/to/NAS/Mount /path/to/NAS/Backup

For the unix, linux and mac osx users that is built in.  For the windows user you can install cygwin.  The first backup will be long and any additional backups would be new and modified files.   There are options to do checksums vs timestamp on the copy along with preserving previous copys on the backup location.

Here is more info about using the Rsynch.  http://everythinglinux.org/rsync/

Perhaps a little over the top but this will be a solution that you are looking for.
