Yes, Bacula modifies atime for all files that it backs up. However, there is
an option "keepatime = yes", which will cause Bacula to reset the atime on
files that it backs up. However, this option does not work until version

Well, if you are starting with 1.37.30 or later, the keepatime option should
resolve your problems.
