Gene,
Did you set maxpromoteday? You should not.
Amanda never promote a DLE if the sum will be larger that the means, eg.
it will never promote your biggest dle, you havr to do it manually with
'amadmin force'.
If oyu want that I look at it, then you post more informations, the
amdump.? log files for the latest 5 runs.

Greetings from the canary;
One of the things that constantly get under my skin is the apparent lack of
amanda's ability to juggle backup order in order to balance the sizes of
the backups from night to night. I have fussed about this before without
arriving at a solution, but it seems to me amanda has gone dumb with all
the re-writes in the last 3 or 5 years.
I am seemingly locked into a cadence of 4 nights worth of doing about 15Gb
a night, followed by the night when it does the largest 5 or so DLE's all
on the same run, which makes that run be 45+Gb.
The biggest one is /usr/movies, at a bit over 16Gb. If I could get that
one separated from the other larger ones, it would help. Sure, I could
comment that DLE out for a day or 2. Or I could force a level 0 on Friday.
The point is that 5 years ago, amanda would do this all by itself and it is
no longer even making the effort for at least the last 2 or 3 years.
Here is the output of amadmin Daily balance:

No huge files to disturb it have been added or deleted in at least a month.
Now it used to be, years ago, that amanda's planner would come within 20-50
megs of filling a 4Gb tape every night for weeks at a time without ever
hitting an EOT. Now it seems as if amanda is making no effort to move that
16Gb movie (its weddings I've shot, all since I moved to vtapes years ago)
DLE to Friday or even Thursday where it would fit quite nicely in the 30Gb
I give it as a virtual tape size.
Do I have it being forced to maintain the existing terrible schedule by
some option with a hidden interaction in my amanda.conf?
Please name that option if there is such a beast.
Thanks.
Cheers, Gene
