Very interesting.
My entire set of backup volumes, currently about 4.2 TB, was rsync'd to a
separate system (no errors) and a restore attempt made there from a fresh
bacula installation (using the same catalog but otherwise different h/w
and s/w). This restore attempt also failed in the identical fashion to
that described previously. The backup volumes are evidently corrupted at
backup time.
On the original director, I then set "Max Concurrent Jobs" to 1 everywhere
and ran a full backup of a 300 GB file system containing 151,155 files.
Same hardware, same software, everything the same except for MCJ=1. I then
restored all of these files without any error, which I have been unable to
do with MCJ=2.
The conclusion is that it looks like there may indeed be a bug.
In any event, I shall run with MCJ=1 for now, and re-run full backups of
all of my data (about 2 TB on this system), and then restore the whole lot
to see what I get. If I get time I will take a peek at the source.
