We have a Windows 95 user here who reported that when he ran an incremental
backup yesterday all of the files on his system got backed up again.
Yesterday was the first day of Daylight Savings Time.
This is the only explanation I can think of that would cause this.
He did not re-label his disk.
I'm thinking that ADSM incorrectly judged that the timestamps on all files
changed.  The "last modification date/time" is identical for both copies
of the backed up files, as is everything else about the file copies.

This is the only W95 user we have, so I cannot check to see if this is
a widespread problem, or something specific to his machine.  Has anyone
else seen this?  Note that unless you look for it, you might not even
notice that this has happened.  Probably the best way to tell is to look
at either the client's scheduler log, or look at the server's accounting
log (to see if an extraordinary amount of data was backed up).

With only one W95 user, this is a mildly interesting bug.  Next year, we
are likely to have hundreds of W95 users and it will be a disastrous bug
(if it is, indeed, a bug at all).

Thanks for any info.
