Configure archive/backup ios devices using SSH; sftp or scp?

[kidseven112002]

Is it possible to configure remote archive/backup of ios devices to an sftp server? I need to archive switch and router configs to a server, but can't use tftp because it's insecure.

You can use scp to  trasnfer the backup to external scp server. sftp doesn't support.

Thank you for the reply. To use SCP do I need to have any ssh authentication configured on the device or is turning on SSH sufficient?
