Hi there,
here some nice script to backup your RouterOS config
using ssh keys
simply generate an ssh key
ssh-keygen -t dsa
copy your public key via ftp to your router and import it
#!/bin/bash date=$(date +%F) router="10.0.0.1" idfile="/user/.ssh/id_dsa" backuppath="/path/to/backups" option="StrictHostKeyChecking=no" ssh -l admin $router -i $idfile -o $option "export" > $backuppath/$router-backup-$date.txt find $backuppath -type f -mtime +14 -exec rm {} ;
Have fun!
