Not sure what trickle does, but I assume it reduces the amount of
bandwidth for your backup. I would suggest that you could do this, but
allow it much more bandwidth. ie, around 70% of the available bandwidth,
so it doesn't take too long, and also it doesn't saturate your network.

Secondly, if you run a full backup of each machine on a different
day/time, then it should eventually even out across the day/week.

Finally, increase the configuration for FullPeriod so that it will only
run a full every 21 days (for example) then tell the people they should
run a backup every week manually. You will probably find that nobody
will manually run the backup, but the longer full period should allow
the recurring backups be less likely to happen at the same time. Now
everyone is happy, except that people don't run full backups as often as
they 'should' :)

Hope that adds some insight to the possibilities for you.

PS, any reason rsync is a no go under vista ? This in my opinion would
be the best solution by a long shot !

Adam
