I believe that ADSM checks for one or more of the following criteria when
determining whether a file has changed:

modification date
modification time
file size

The archive bit is not used.

In the UNIX environment, I think that ADSM also considers changes in the
owner or permissions.

Other factors come into play as well, including:

Whether the file is excluded in the INCLUDE/EXCLUDE options
Whether the minimum number of days between backups (FREQUENCY setting
  in the management class) has passed.
