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!
