Rsync Doesn't Want To Transfer Files

i have a client machine which requires backing up, and the server. For some reason, rsync doesn't want to transfer files...

i've already set up keys, it logs in fine without asking for password.

server config:

max connections = 2
log file = /var/log/rsync.log
timeout = 300

[backup]
comment = Rsync backups
path = /secondary/client
read only = no
list = yes
uid = nobody
gid = nobody
auth users = root

client command:
rsync -vz --recursive --progress --stats -e "ssh -i /root/.ssh/rsynckey" root@server.com:/backup/ /home/usertobackup

it keeps saying cannot find the backup folder, even thouhg it does exist on the server and is what is specified in the path above?
