Questioner --
There is very little information available right now on Project Server 2007,
simply because the software is so very new. We are currently working on our
first two books on Project Server 2007, but they won't be published any time
soon. So, you are wise to ask your question in this newsgroup.
Essentially, the Archive database is where the Project Server administrator
can back up enterprise objects, either manually or on a regular cycle. The
Project Server administrator can back up enterprise projects, the Enterprise
Resource Pool, the Enterprise Global file, and other objects as well. If
need be, the Project Server administrator can then individually restore any
of the backed up objects. Is there more you wish to know? If so, let us
know. Hope this helps.
