backup w/o being logged in?

I don't think the drive mounting is the real issue as much as SD isn't mounting the sparse image. Here's why I think that. Since all this started a couple weeks ago, I've been trying several different scenarios to get my daily backups going again. The one that I got to work, is to avoid backing up 1 of the two internal drives and simply use the entire external drive to backup the main internal drive (not using a sparseimage, but the entire disk) This works with no one logged in! So it's obvious the drive is mounting, even when no one is logged in. Problem is, I'm not getting to back up my other internal drive anymore (though it's not the main drive, it still gets used). So my real question is, if utilizing the sparseimage method, why does SD not "mount" the disk? BTW, I can tell the disk really is mounted even under this scenario as I can log onto this mac via FTP using my MacBook and see that it is mounted. Why doesn't SD recognize it?
