My first thought when I heard about the Lotus Notes agent was that a datbase
restore would take much longer because the various documents could be spead
over several tapes and if we had to do a server restore, what used to tae 7
hrs could take a day. Has anyone had any experience with this? Thanks.

What you are saying is true to an extent. Because the backup for Lotus
Notes is at the document level, it's somewhat analagous to backing up
a bunch of files, rather than just one large object. So, like any other
ADSM client, the backups could be spread over multiple tapes. This can
be mitigated, however, by storing the Lotus Notes Agent backups in a
collocated tapepool. If you don't use collocation for your existing
tape pool(s), consider creating a new tape pool just for the Lotus
Notes Agent that *is* collocated.
It is my experience that overall through-put of the Lotus Notes Agent
is slower compared to backing up the same amount of data with a regular
ADSM backup/archive client. I believe that this happens because for
each document, the Lotus Notes Agent has to make calls to Lotus Notes
itself, which slows it down.
You should consider using the regular ADSM backup/archive client in
tandem with the Lotus Notes database. That is, make periodic full
backups of the entire Notes database using the backup/archive client,
and incremental backups with the Lotus Notes Agent in-between. While
you don't *have* to do this, it will help speed up the recovery process,
especially for huge databases (i.e. with lots & lots of documents),
because the amount of data to be recovered incrementally is reduced.
