You could set BM_LOGGER_LEVEL to "debug", maybe that helps. There is
also an undocumented "-d|--debug" option for backup-manager. Otherwise,
insert a "set -x" at the beginning of /usr/bin/backup-manager and you
will be overwhelmed by its verbosity. ;-)
BTW, what are your tar and libc6 versions?

Sven
