[ i fear that, at this point, this only serves as a oddity i have seen
and reported just in case someone else sees something similar and the
two clues can be summed ]

no blame, was very very strange. never seen anything like it before.
and i pieced my world back together, with very little loss, as there
were other modes of backup in place, belt and braces. i only actually
lost some months of mail in imap folders of procmail mailing list spew,
such as freebsd-current.

9-[then-]current. the machine is the one server which only has my
personal crud, so it is the bleeding edge. it converted to -10 about
when the problems with backup content seem to have started last
(northern hemispheric) summer. so the issue could have been some file
state that happened long ago and just did not surface until the much

i guess i could restore a dump and find out.

quite likely. a neighbor on the same vmware host did some exciting
resource demand messes the other month.

/usr/home not being backed up. among other things, /usr/home/randy/rair
contains a unison rsync of my laptop's ~randy, i.e. it's large.

not sure what it is you expect

checked (very pseudo) random directories and filesystems. all good.
