Windows Server - ADAM Backup generating an Event 2089

I have two adam instances installed in a domain. The OS they are running on
is Windows Server 2003 R2 SP2. I have been performing NT backups of the
entire "C" drive where ADAM is installed as well as a system state backup of
the machine. I am getting Event ID 2089 warning messages in the ADAM event
logs that the partitions need to be backed up. I opened up a case with MS
about this in February of 08 and they told me it was a bug with the VSS
writer updating the dsasignature attribute. My question is if I continue to
get these messages the user objects in ADAM will not tombstone? Is that
correct? I.e. If Adam was never backed up would it start tombstoning objects?

Hi

I remember this issue and reproduced and reported it, did you not
get any follow-up from PSS as to a fix?

The warning should is just that a warning it tries to tell you about how
useful your backups are relative to the tombstone lifetime however
due to the bug the system does not know when your last backup
was, so long as you know that your backups are not older than
the tombstone lifetime you should be OK [1],[2]
