execution fault

[Jamie Heilman]

long shot, but maybe check your /etc/ld.so.conf on both machines to
see if they are different, perhaps the user you are testing with's
environment is augmented so you don't notice the difference when
testing but when actually running the backup it bites you...
See ld.so(8) for other various things that could be clues.
