Hi All,

     We backup our DFS filesets via ADSM as mountpoints on an AIX box, as
we run the Sun Server, and the Sun Client does not have DFS support.  We
are doing it this way because the buta tools only backup/restore at the
fileset level, and we do not want to have to restore entire filesets to
alternate locations, and then grovel through that looking for one file.
ADSM gives us file-level detail, as well as a single tool, as Curtis
points out.  There are some caveats with using ADSM this way, like the
user being able to change the ACL's such that we cannot back the file up,
and the user creating a loop in the filesystem by creating a mountpoint
that points back into the tree, but we see these as more managable
problems than using buta/butc.

Hope this helps,
