when I run rsync without the --ignore-existing switch on N900, all files I am trying to synchronize are retransfered, even the source and destination files are the same. With the switch it runs quickly but I don't think old files on N900 will get updated.

I use the same command for PC to PC synchronization, which works flawlessly. Is this a bug in N900's rsync?

Here's my rsync command:
rsync -ortv --exclude '*~' --delete -e ssh me@192.168.1.20:/home/singleton/music/ /home/user/MyDocs/.sounds/
