Openmediavault Usb Backup [new] Jun 2026

This plugin is perfect for the "Home Sysadmin" who wants to follow the 3-2-1 backup strategy. If you have a dedicated USB drive that lives in a fireproof safe or at a relative's house, and you bring it home once a month to sync data, this plugin is the best tool for the job.

| Pros | Cons | | :--- | :--- | | Automates the 3-2-1 backup rule (local + off-site). | File System: Requires ext4 for best results, making drives unreadable by Windows/Mac by default. | | Rsync Power: Uses the industry standard for file synchronization; reliable and fast. | No Encryption: Out of the box, it does not encrypt the backup drive. If you lose the drive, your data is exposed. | | Versioning: Supports hard links to keep historical versions of files. | Large Drive Handling: If your USB drive is smaller than your total data, you must be very specific with your job selection; it won't auto-span multiple drives. | | Visual Feedback: Can configure email notifications upon completion or error. | USB Specific: Not a solution for remote/network backups. | openmediavault usb backup

If you need cross-platform compatibility (moving the drive between Linux and Windows frequently) or require heavy encryption for sensitive data on the go, you are better off using a Docker container (like Duplicati or Syncthing) or configuring a manual rsync script to an encrypted NTFS drive. This plugin is perfect for the "Home Sysadmin"

Unlike standard RSync jobs that run on a schedule, this plugin initiates the synchronisation process as soon as a recognized USB device is plugged in. | File System: Requires ext4 for best results,

It does one thing and does it perfectly: automating USB synchronization. It loses points only for the inherent friction of Linux file system permissions when dealing with external drives in a mixed-OS environment.
