What is indicating to you that a directory path is built incorrectly?
The part that says:

a directory (while removing /var/lib/backuppc/pc/kestrel/268/XXXXX/f.cache)
BackupPC has somehow concatenated the mount path and the symlink path
and come up with balderdash. I've started on tracking it down by
means of log statements, but what with all these alligators time has
been a bit short.
Does it make sense to focus on rsync first?
Well it's rsync_bpc not rsync, and I have no idea, but vide infra.
Is [the correct way to reduce the storage used by V4] documented?
I guess I'll just leave this hanging and hope for the hive to come up
with something.

Regarding this point: have you tried reducing the parameter
PoolSizeNightlyUpdatePeriod? ... forcing it to check the size in a
single night ... for a couple of days solved it.
Oh, dammit, thank you! I remember seeing that when I trawled through
the new configuration options and then forgot all about it. I set it
to 1 last night, before the nightly backup run, then stopped BackupPC,
killed the ten-day-old rsync_bpc, restarted BackupPC and hit the sack.
This morning normality seems to be restored, at least the crazy usage
figures have disappeared and the V4 pool size looks sane again:
8<----------------------------------------------------------------------
Pool is 940.29+987.81GiB comprising 1757074+1459146 files and 16512+4369
directories (as of 2018-09-19 01:29),
Pool hashing gives 1678+1909 repeated files with longest chain 7+4,
Nightly cleanup removed 6436+10275 files of size 135.04+0.26GiB (around
2018-09-19 01:29),
Pool file system was recently at 75% (2018-09-19 08:49), today's max is 80%
(2018-09-19 01:00) and yesterday's max was 80%.
8<----------------------------------------------------------------------
There were log messages for over 17,000 missing pool files but I'm
guessing that this is probably the result of my manually running
BackupPC_backupDelete. I haven't had a chance to investigate that
but I will do later.
Thanks again!
