rsync - Feb 2005 - No incremental copies to localhost

Hi everyone

I am trying to update an mp3 archive from my hard disk to an mp3 player
over a usb link, e.g. after ripping a few new cd's. I seem not to be
able to get rsync to traverse the archive and only write the new files
accross. Instead it copies everything over again, which takes very
long.

I have tried some combinations of options, e.g.

rsync -va SRC DEST
rsync -va --no-whole-file SRC DEST

Each time I get something like:

wrote 51751332 bytes  read 135874 bytes  437866.72 bytes/sec
total size is 51761152  speedup is 1.00

, which I understand as that a straight/full copy took place, even
though the data is already at the destination.

I could not find anything related in the archives or Google, although I
could have missed it.

I have Cygwin's rsync v 2.6.2 on a Win2000 PC.

Thank you

Alexander

As long as the file's modification time and size are identical on the
source and destination, the files will not be copied.  So, as long as
you're preserving the file's time (via -a or -t), all should be well.
So the first thing to look into is listing those attributes on both
sides and seeing if they match (you should list the mod-time down to
the second if you want to see if they really match).

You can also try the --modify-window=1 if the problem is that the
timestamps on the receiving side are off-by-one from the sending side.
