To mitigate the risks associated with backup file manipulation:
Once decoded, the tool extracts the configuration into a local directory structure or a SQLite database file. This database represents the RouterOS configuration tree.
If the backup is encrypted, you must decrypt it first.
Once unpacked, you can perform tasks like "resetting a password" by replacing the user.dat file with one from a fresh, default router configuration.
./ROSbackup.py pack -d unpacked_folder -o Modified.backup open mikrotik backup file repack
Go to the menu, find full_config.rsc , and drag it to your desktop.
Reverse the process with the :
If your goal is to have a file you can easily edit and "repack" manually, you should use the method instead of the Backup button. Mastering MikroTik Backups - Free MTCNA Ep.9
In modern RouterOS versions (RouterOS v6.x and v7.x), backup files are encrypted using RC4 or AES algorithms depending on your configuration and software version. The data payload inside the backup is also compressed to save space. This means you cannot simply open a .backup file in a text editor like Notepad++ or VS Code and expect to read the data. 2. The Danger of Manual Repacking To mitigate the risks associated with backup file
If you want to protect the file before uploading it back to the router. ./ROSbackup.py encrypt -i NewPlaintext.backup -o FinalBackup.backup -e AES -p newpassword ⚠️ Critical Warnings
Place your target backup file (e.g., router_prod.backup ) into the tool directory.

Before attempting to crack open a backup file, it is vital to know exactly what kind of file format you are working with.
