dumpcycle is just the maximum time between fulls. Amanda
often schedules them sooner if it thinks it will level out
daily tape usage. I don't know how it handles a single
DLE, as that is not really what it was designed for.
If you really want it to always be the same day, you
might be able to force it with a maxpromoteday setting,
but it may be easier to just use two configs, an always-full
one that runs on the prefered day, and an incremental-only
one that runs on the other days.
