Duplicacy: One Backup Engine to Cover It All

What is Duplicacy?

Duplicacy is a backup tool for people who’ve had enough of half-baked solutions. It’s cross-platform, supports cloud and local storage backends, does deduplication, versioning, encryption — and still manages to be fast and quiet.

It doesn’t try to be flashy. You won’t find an overcomplicated GUI or endless pop-ups. What you will find is a backup system that’s rock-solid, efficient, and built to run unattended — whether that’s on a personal laptop, a team server, or a headless cloud instance.

If you’ve ever juggled rsync, rclone, cron jobs, and scripts just to keep backups running — Duplicacy was built to make that juggling act unnecessary.

How It Works

At its core, Duplicacy uses deduplicated snapshots — meaning if you back up the same file (or part of a file) across machines or versions, it only stores it once. That alone saves a ton of space, especially in team environments with lots of shared data.

It’s built to work with almost any storage backend: local disks, SFTP, Amazon S3, Backblaze B2, Google Drive, Dropbox, Azure, Wasabi, and more. And yes — it encrypts everything before sending it out, with zero reliance on the provider’s encryption settings.

Jobs can be scheduled via command line or run manually. There’s also a GUI for those who want it, but under the hood it’s the same fast, Go-based engine.

Key Capabilities That Matter

Feature Why It’s Useful
Cross-Platform Works on Windows, macOS, Linux — same core across all OS
True Deduplication Stores chunks only once, even across devices and backups
Cloud + Local Targets Supports most cloud storage providers and file systems
Snapshot Versioning Keeps historical versions, efficiently
Strong Encryption Zero-knowledge AES-256 encryption before upload
CLI + GUI Support Command-line automation or simple graphical interface
Concurrency-Friendly Multiple machines can back up to the same storage safely

Getting Started (Without the Headache)

1. Download
Head to https://duplicacy.com and grab the latest version for your OS.

2. Choose Interface
Use the GUI version if you prefer buttons, or the CLI if you’re scripting or headless.

3. Initialize a Repository
Point Duplicacy to a folder — it treats that as a repo. Choose your storage backend (local or cloud), set encryption and retention options.

4. Run a Backup
Execute the backup manually or set it to run on a schedule (Task Scheduler, cron, etc.).

5. Restore When Needed
Restore any snapshot, from any point in time, to any location — including partial restores.

Real-Life Usage Scenarios

– Personal workstation backups: Automatically encrypts and sends snapshots to cloud storage without slowing the system.
– Dev team shared storage: Multiple users backing up to the same bucket with zero collisions, thanks to deduplication.
– Remote server protection: Lightweight binary runs via cron, backs up full volumes to Wasabi or Backblaze.
– Compliance scenarios: End-to-end encryption + snapshot retention = easy audits and data rollback.

Stacking Up Against Alternatives

Tool Pros Cons
Duplicacy Fast, deduplicated, encrypted, multi-platform License required for CLI usage
BorgBackup Efficient, battle-tested on Linux Linux-focused, complex for newcomers
Restic Easy CLI, good cloud support Slower deduplication, no GUI
Arq Backup GUI focused, user-friendly macOS/Windows only, more consumer-grade

Why It’s a Favorite for Many Admins

What makes Duplicacy stand out is the balance — it’s flexible without being fragile, powerful without being bloated. Once configured, it disappears into the background and just works. It doesn’t try to own your system. It doesn’t break with every update. It just keeps backing things up — cleanly, securely, and silently.

And when things go wrong? Restores are quick, reliable, and painless. Which is ultimately what matters.
