I just did my first succesfull rsync backup. Well, I just copied some
directories from one place to another on my hard disk :-) I tried to
copy to a CD-RW too, but it didn't work. I got the following error
message:

ERROR: destination must be a directory when copying more than 1 file
rsync error: errors selecting input/output files, dirs (code 3) at
main.c(371)
rsync: connection unexpectedly closed (8 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(359)

I tried to use hdc, cdrw, cdrom, cdrom0, cdrom1, with and without sudo
as a destination. I also tried creating a directory to the disk, because
the error message above said something about it. None of this worked.
Man pages of rsync say nothing about syncing to CD-Rs or CD-RWs. Is this
supposed to work?

Anyone? :-)
