Cleanup of slave PFSes

I have trouble understanding how daily cleanup jobs interact with slave
PFSes being updated with
I have a hammer volume (ROOT) of a size of about 150GB with a number of
PFSes on it.
All PFSes are mirrored to another volume (BACKUP) of the same size, to
slave PFSes with the same name.
BACKUP is mounted on /backup, so for example /pfs/data is mirrored to
I noticed that while the nightly job runs hammer cleanup just on the
PFSes on the ROOT volume, not on BACKUP,and in fact the free space on
BACKUP keeps getting lower.
Manually running `hammer cleanup` on the slaves recovers only a portion
of the space, not all. Is there a reason for this behaviour, or is there
something wrong in my configuration ?
Anyway, how can I enable the cleanup of PFSes other than in the ROOT
volume ? Is there a reason why this is not done by default ? Just
pointers to documentation would suffice (I checked hammer(8), but I
didn't find anything relevant).
Thanks in advance,
