/scripts/cpbackup -> /dev/sdb1 already mounted or /backups busy??

[ttk_2k]

Hello, I'm quite sure that I have set everything followed by some instructions for cPanel daily backups, but I'm still getting this message in my mailbox everyday:

mount: /dev/sdb1 already mounted or /backups busy
mount: according to mtab, /dev/sdb1 is already mounted on /backups

Anyone can help? Thanks a lot!

EDIT: I have optioned "Remount/Unmount backup drive" in WHM, and I see /dev/sdb1 is not mounted on /backups normally, so why I'm still seeing the above message?

ok, found the problem:

Because I was configuring my server these days, so I was rebooting my server everyday, whenever I rebooted the server, the /backups mounts automatically, that's why I receive above messages.
