Ashley,

I'm not sure what distro you're running,but it is using SYS V based 
controls.  In my backuppc init script I have the line:

-------------------------------------------------------------------------------------
# chkconfig: - 91 35
-------------------------------------------------------------------------------------

I would recommend writing a small init script to handle this that 
started at:

-------------------------------------------------------------------------------------
# chkconfig: - 90 40
-------------------------------------------------------------------------------------

This will ensure that it mounts the file system before BackupPC starts 
and it will unmount it after BackupPC is halted.  If you use rc.local, 
the file system will not be mounted until after all other services, 
including BackupPC, have started.  This may or may not cause you 
issues.  If you use a script to do this you can prevent that.

Thanks,

Ronnie Gilkey
