If the info command returns cleanly without errors, the backup file is likely valid. For complete confidence, you should test the backup by restoring it on a non‑critical router (preferably a lab device or virtual RouterOS instance) before relying on it in production.
Never use these tools on backups from untrusted sources, as the unpacking process could potentially execute malicious code or write to unauthorized directories. open mikrotik backup file repack
When you open a backup, certificates are exported as encrypted blobs. Repacking them without the original key store breaks SSL services (Winbox, CAPsMAN). Use /certificate export in plain RSC before creating the initial backup.
Now, open config_dump/config.rsc in any text editor. You have opened the backup.

If you are locked out of a router but have an old backup, you can locate the user database file, clear or replace the password hash, and prep the file for reloading.
MikroTik’s native backup is a proprietary, binary, encrypted (optionally), and compressed file. You cannot cat it, you cannot grep it, and you certainly cannot paste it into a text editor.
Before attempting to manipulate a backup file, it is vital to understand what happens under the hood when a MikroTik router compiles a .backup archive. 1. Encryption and RC4/AES Now, open config_dump/config
This yields a plain .rsc script file you can edit and then re‑import.
In practical terms, a RouterOS backup is a complete snapshot of a specific router. It is intended to restore the exact same device or a different identical model when the original router fails. This is one of the most important distinctions to understand: a backup file is designed for device replacement, not for configuration migration between different devices.
