There is a technote for Windows 2000 that explains which files TSM excludes from backup. http://www-1.ibm.com/support/docview.wss?rs=663&context=SSGSG7&q1=filesn ottobackup&uid=swg21049023&loc=en_US&cs=utf-8&lang=en Unfortunately I couldn't find such a technote for unix systems - but if memory serves me well there is such a beast. Anyone has a link?
