BmuS

BmuS is a powerful free backup program for the automated backup of files, directories, and MySQL databases from a Linux / Raspberry Pi system to a NAS or network drive. It features a dashboard, encryption, deduplication, and much more.

BmuS was developed with low-resource systems in mind, enabling single-board computers such as Raspberry Pi to run it efficiently.

One of the key features that has received special attention (or is it called “Love”?) is the dashboard. The pro version of the dashboard does not only provide simple status information, but also includes trend analyses (such as size growth, duration and more) and displays the backup history of the last 30 days.

Key functions:

🔄 Rsync-based: Efficient transfer, only changed files are copied.

🔗 Deduplication: Uses hardlinks to save storage space. You have access to full snapshots at any time without using up storage space for unchanged files.

🔗 Automatic verification of data integrity

🔐 Encryption:

File system encryption with gocryptfs (filenames & contents encrypted). GPG encryption for SQL database dumps. Restore: Built-in restore mode for individual files or entire backups (including from encrypted sources). Layer 1: gocryptfs for file system encryption Layer 2: GPG for additional archive encryption Layer 3: SMB3 encryption for network transmission

📊 Dashboard & Reporting:

In the Pro version, BmuS generates an HTML5 dashboard with charts (Chart.js) for analyzing memory usage, trends and errors. 10+ visualization types Email notification with log file and dashboard attached.
