As is said in the monthly TSM FAQ (which I haven't posted this month! sorry, 
folks) it states:

"04-19.  My scheduled backups fail (or are incomplete), but my manual ones 
          work fine. Why?
This almost always occurs in Windows servers, and it's always a Windows 
permissions problem. By default, the TSM scheduler runs as a service with 
System account privileges. By default all Windows files are read/writeable by 
System; however, there are a few Windows admins (and applications) out there 
who remove System privileges from files. (For what reasons, I cannot imagine.) 
When a manual backup is run, it uses the permissions of the account of the 
person who is logged on, not the System account. (You can't log on as System, 
as it's a non-interactive account.) The real solution is reset all files to 
have System read/write privileges. If that's not possible, you need to alter 
the scheduler service so as to use a logon ID with privileges that have access 
to all files that you want backed up. Remember that if that logon ID changes 
passwords, you're going to have to update the service properties to reflect the 
new password."
