Also, instead of -a use -rt. Those are the only parts of -a that FAT
even pretends to support.

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).

I am trying to use rsync between two local directories on Linux.
The source directory is on a normal ext4 partition, under my home
directory. The destination is an SD card that I insert into the card
reader on the computer, formatted with a vfat filesystem.
The command line is like
rsync -avC --delete /home/itz/foo/ /media/itz/DEAD-BEEF/foo/
This does not work as I expected: all files are always transferred,
even when I run this command 2 times with nothing in between. I
expected only new or changed files to be transferred. Is this
- a user error
- a rsync bug
- a limitation of the vfat filesystem?
In any case, what can I do, using rsync or possibly something else, to
do what I want? I note that the absolute timestamps on the files are
unimportant; I can change them to whatever. All that matters is that
new and changed files are copied every time I run this command, and
only those files.
