You would only want that if you've been down long enough to get behind. When
you add a new host, if it isn't already the time you want it to start you can
go
to it's page in the web interface and click the stop/dequeue backup button
(even
though one isn't running yet), then put in the time you want to wait for it's
first run. After that, the normal scheduling will make the fulls happen at
approximately weekly intervals. If you have gotten off schedule you can fix it
manually by forcing full runs ahead of time for a few machines each evening to
adjust the skew. Just keep in mind that this may 'age out' your oldest full
sooner than you would expect, depending on your configuration.
