Of course, if you are using the agent to back up a database where the majority
of data is changing every day, then you will be better off doing full backups
using the adsm client. There is some break-even point, but I have no idea what
it is. It all depends on how the is database is structured. From the brief
testing I did, the agent was about 3x slower doing a full backup then the adsm
agent, which ain't bad for an agent.

Nick, I'd like to understand your performance concern.  The agent should
definitely reduce your backup time because it is incremental....only backing
up the notes/docs that have changed.  So the amount of data you are backing
up daily should be substantially reduced.
The first time you run the backup with the agent, it will take a long time
because it is backing up every note/ is breaking up the databases
into individual notes/docs/forms/views.  But after this first time, the
rest is incremental forever with the never do a full backup
with the agent again.
