[ubuntu] rsync with ssh - asking for password after keygen

view story

http://ubuntuforums.org – ive set up passwordless ssh by running ssh-keygen , then swapped keys using ssh-copy-id . i can login without being asked for a password if i just type in ssh [email protected] , but when running this rsync command i get prompted for a password on the remote machine. im transferring data from a remote machine to a local computer, and im running rsync from the local machine. sudo rsync --delete --progress -azvv -e ssh [email protected]:/home/remote/Documents/ /home/local/Documents/ could it be that when i created the keys i didnt add these options? and thats whats causing the problems?
