Se estou entendendo corretamente, descobri que alguns servidores SFTP não suportam chaves ssh e, portanto, o rsync não funciona (reports.paypal.com como exemplo). Nesse caso, você precisará fazer script para fazer o sftp, você pode usar o expect for this ... Aqui está um script que deve funcionar para você:
#!/bin/sh
bname='basename $0'
usage () #usage instructions
{
cat <<EOF
syncs LOCALPATH to REMOTEPATH on sftp://SERVICE
Usage : ./$bname [-s SERVICE -l LOCALPATH -r REMOTEPATH] [-h]
-h display this help text.
Example: ./$bname -s your.sftpserver.com -l /tmp/A -r /tmp/B
will upload any missing files from /tmp/A to /tmp/B
EOF
exit 0
}
upload ()

if [ $? -ne 0 ]; then
echo "Please enter username for sftp://"$SERVICE
read username
echo $username > .credentials_tmp
read -p "Password:" -s pass
echo $pass >> .credentials_tmp
else

Para usar, basta salvar o código em um arquivo, por exemplo uploadsftp.sh e execute chmod u+x uploadsftp.sh
Em seguida, você pode configurar o cron para o cd no diretório do script e executar o script: ./uploadsftp.sh -s SERVICE -l LOCALPATH -r REMOTEPATH sempre que precisar.
