Yes !
But the effort of writing the new rsync 'in between' seems not so easy.

Because of each host config in backuppc, need to be respected.
May be a wrapper of the original rsync command used by backuppc.

But your suggestion seems good.
Because, I've the same sort of result on the secondary, a full tree with 
every host.

I had to rethink about the whole picture.

The storage is best on my secondary, but it is off site for all final 
host target.

what about the purge, on the middle storage, rsync --delete ?

right.

I will extract a full 200Gb each time.
Which need to be optimized...


Study of your other suggestions, about how to approach the "scheduler 
simulator" and the "blackout generator", next time.
Thanks for your time.
