Always use strong, complex passwords for encrypted backups. Treat a .backup file with the same sensitivity as the root access to the router.
user.dat or database files containing user credentials (often hashed or encrypted). System identity configuration files. Binary configuration state trees.
This command will tell you whether the backup is encrypted, which encryption algorithm was used, and other metadata. This information is critical before proceeding with decryption.
And then you can import modifications:
There are times when network administrators need to open, modify, and repack a .backup file—such as recovering lost passwords, migrating configurations to different hardware revisions, or mass-provisioning devices with slight alterations. This article covers the structure of MikroTik backup files, how to extract them, and how to safely repack them. Understanding the MikroTik .backup Architecture

The Deep Dive: Decoding and Repacking MikroTik Backup Files For most MikroTik users, a open mikrotik backup file repack
Before you open or repack a backup file, you should first ask yourself whether you truly need to work with a .backup file at all. RouterOS offers two completely different approaches to configuration management:
Use a specialized tool like mtpack to recompress the files.
Drag and drop your final_repacked.backup file into the Files window. Always use strong, complex passwords for encrypted backups
./ROSbackup.py bruteforce -i MikroTik-encrypted.backup -w wordlist.txt
There are several reasons why you might want to open a Mikrotik backup file:
The cleanest way to "repack" a modified backup is to skip rebuilding the binary file altogether. Instead, convert your changes into an .rsc script. Save your edited configurations with a .rsc extension. System identity configuration files
When working with Mikrotik backup files, it's essential to follow best practices to ensure the integrity and security of your network:
: Use a tool like marcograss's unpack command to extract the binary contents of a plaintext (decrypted) backup.
