You can find these details in the BA client manual (for Windows it's
Chapter 4) "Backing up your data"

Reference section "Performing incremental, selective, or
incremental-by-date- backups"

Subject: [ADSM-L] TSM client checklist for backup.

Is there a list of what the TSM client checks for on a file to determine
if
the file needs to be backed up? I have a client that is running both
BackupExec and TSM on servers and he's telling me that TSM backs up way
more
than backupExec and 'what the users have changes.' Using their words.

This customer also has TPC Data and is using the Files as Risk report to
estimate how much data needs to be backed up. But I think that just goes
on
the archive bit and the last modification date/time of the files. Which
is
only a fraction of what TSM uses to determine a file's eligibility for
backup.

TIA,
