Re: Archiving to vfat

it's most likely because of vfat timestamp limitation

try

--modify-window
               When comparing two timestamps, rsync treats the
timestamps as being equal if they differ by no more than  the modify-window
               value.   This  is  normally  0 (for an exact match), but
you may find it useful to set this to a larger value in some situa-
               tions.  In particular, when transferring to or from an MS
Windows FAT filesystem (which represents  times  with  a 2-second
               resolution), --modify-window=1 is useful (allowing times
to differ by up to 1 second).
