MikroTik backup files are proprietary binary archives. They contain the RouterOS configuration database, including interface settings, firewall rules, IP addresses, and user credentials.

It is important to distinguish between two types of backups: open mikrotik backup file repack
python3 /tools/rsc_extract.py /tmp/extract_raw/store --output /tmp/rsc_dump/
This is how professionals deploy mass updates without touching each device. MikroTik backup files are proprietary binary archives
You cannot just rename a .txt file to .backup. The checksums and binary headers must be perfect.
Command structure for repacking:
python3 backup_pack.py --input modified_config.rsc --output custom_firmware.backup --routerboard RB4011 --version 7.12
