According to
http://www-01.ibm.com/support/docview.wss?uid=swg21417529

During snapshot difference incremental backup of N-Series or NetApp volumes, if 
files are skipped due to any reason, such as Tivoli Storage Manager server 
media mount being unavailable, these files might not be backed up during 
subsequent backups either, unless the files have been modified. Such files will 
be logged to the TSM error log. You can back them up manually or perform a 
snapshot difference backup with the option "createnewbase" set to "yes".
