SBS 2003 Backup Error

I have a SBS 2003 with about 40 users.  The built-in ntbackup.exe routine runs daily at 10pm.  Recently, it began failing when trying to back up a specific partition.  It backs up the first 3 partitions, "C (system)", "D (databases)", "E (exchange)" successfully.  When it reaches the "F (user files)" partition it fails.  The F drive is where all of the redirected My Documents folders and other user files are located.  All 4 of those partitions are part of the RAID.  They get backed up to an internal non-RAID member drive.  There is plenty of space and the rest of the backup finishes correctly and can be read and restored from.  Additionally, if I manually run the ntbackup on the F drive it succeeds every time.

The error message in the backup log (I pasted only the relevant section) states:

It seems the ntbackup.exe utility is being run by a system account that doesn't have full access to the entire F drive but I have no idea how to verify what account is being used or whether it has permissions to all of the user data.  

Any ideas?  Thanks in advance!
