Great info Andy. What version did this approach start with, as in the
past I have been experienced that when our security department changes
ACLS (Win) on a file server TSM historically has re-backed up all files
associated with the change, but I haven't checked it in some time to see
if it still happens.

Just to clarify:

- When a file is backed up, it's "simple" or "basic" attributes are
backed
up with that file.

- During incremental backup, if only the basic attributes change, then
the
entire file is not backed up again. Rather, just the attributes are
updated for the active backup version. The attributes for older backup
versions are not changed.

- This behavior applies not only to Unix and Linux, but to Windows as
well.
