Well perhaps not. I posted an earlier email where I am tranferring a
lot of file data for old files that are in prior level 0 backups and
are in the cpool.
So far debugging seems to have ruled out corrupted cpool copy of file
(zcat of the file has same sha1 checksum as the file on the client).
In my case we have 32 and 64 bit linux intel/amd systems.

Hopefully this exploration will also fix some bug that may be
impacting me as well with a real rsync and File::RsyncP.
