Actually bacula uses ctime by default, not mtime.

According to the documentation for File Set options  ( 
http://www.bacula.org/manuals/en/install/install/Configuring_Director.html#SECTION00670000000000000000 
), if you set keepatime=yes WITHOUT also setting mtimeonly=yes, bacula 
will back up every file every time, even for incrementals.  HOWEVER if 
the OP is literally using one file set definition for multiple hosts, 
then he should expect to see this behavior on all of those hosts, not 
just the one.

One possibility which occurs to me is that there may be some kind of 
time synchronization problem between the director and the client.  I 
suspect the problem as described could be a result of the client's clock 
being too far ahead of the director's.  I would suggest verifying the 
client and director's clocks more or less agree.  This may be a 
non-obvious issue if the client and director are in different time zones 
-- or, more to the point, if one of them is in the wrong timezone.
