Duplicacy — cross-platform backups with deduplication that works everywhere

Duplicacy is a backup tool that focuses on making deduplication work across multiple machines and storage locations. It’s available for Windows, macOS, and Linux, and can run either as a command-line tool or with a GUI client.

The main selling point: all backups, no matter which machine they come from, can share the same storage and still deduplicate against each other. That means less space used if you’ve got similar data across systems — useful for corporate fleets or dev teams with shared codebases.

It supports a wide range of destinations: local disks, NAS shares, SFTP, cloud buckets (AWS, Backblaze B2, Google Cloud, Azure), and more. Client-side encryption is built in, so untrusted storage locations aren’t a problem.

Capabilities

Feature Description
Cross-Platform Windows, macOS, Linux
Global Deduplication Identical data across different machines is stored once
Destinations Local, NAS, SFTP, and multiple cloud providers
Encryption Client-side, protects data before it leaves your system
Scheduling Automated backups via built-in scheduler or system tools
Pruning Configurable retention for old snapshots
Compression Reduces storage usage alongside deduplication
Restore Options Restore whole backups or single files/folders

Deployment Notes

– One storage repository can serve many clients — plan naming conventions early.
– Encryption keys must be stored safely; losing them means losing access to the data.
– Command-line version is lighter and more scriptable; GUI is better for end users.
– Deduplication savings are best when multiple machines have similar data sets.
– First backup is always full; after that, only new or changed data is sent.

Quick Start (Example for Linux CLI)

# Initialize storage
duplicacy init mybackup sftp://user@host/path

# Back up a directory
duplicacy backup

# List backups
duplicacy list

# Restore files
duplicacy restore -r

Where it’s useful

– Backing up multiple similar systems to the same cloud bucket.
– Small teams sharing large codebases or datasets.
– Mixed-OS environments needing a single backup tool.
– Offsite encrypted backups to public cloud without trust issues.
– Situations where storage efficiency matters as much as reliability.

What is Duplicacy?

Duplicacy is a powerful and versatile backup tool designed to help individuals and organizations protect their valuable data. It offers a range of features that make it an ideal solution for those looking for a reliable and efficient backup system. In this article, we will delve into the world of Duplicacy, exploring its key features, benefits, and use cases.

Key Features of Duplicacy

Incremental and Synthetic Full Backup

Duplicacy offers incremental and synthetic full backup capabilities, allowing users to create backups that are both efficient and comprehensive. Incremental backups only capture changes made since the last backup, reducing storage requirements and speeding up the backup process. Synthetic full backups, on the other hand, create a full backup from a series of incremental backups, eliminating the need for periodic full backups.

Retention Policies

Duplicacy’s retention policies allow users to define how long backups are kept, ensuring that valuable storage space is not wasted on outdated backups. By setting retention policies, users can automatically delete backups that are no longer needed, keeping their backup repository clean and organized.

Offsite Copies and Immutable Storage

Duplicacy enables users to create offsite copies of their backups, ensuring that data is protected even in the event of a disaster. Offsite copies can be stored in a variety of locations, including cloud storage services, external hard drives, and network-attached storage devices. Additionally, Duplicacy’s immutable storage feature ensures that backups cannot be modified or deleted, providing an additional layer of protection against data loss.

Why Retention Policies Matter

Reducing Storage Costs

Retention policies play a crucial role in reducing storage costs. By automatically deleting outdated backups, users can avoid wasting storage space on unnecessary data. This is particularly important for organizations with large amounts of data, as storage costs can quickly add up.

Improving Data Management

Retention policies also improve data management by keeping backup repositories organized and up-to-date. By automatically deleting outdated backups, users can ensure that their backup repository only contains relevant and useful data.

Incremental and Synthetic Full Backup Tutorial

Step 1: Configure Your Backup Repository

To get started with incremental and synthetic full backups, users must first configure their backup repository. This involves setting up a storage location for backups, such as an external hard drive or cloud storage service.

Step 2: Create an Incremental Backup

Once the backup repository is configured, users can create an incremental backup. This involves selecting the data to be backed up and choosing the incremental backup option.

Step 3: Create a Synthetic Full Backup

After creating an incremental backup, users can create a synthetic full backup. This involves selecting the incremental backup and choosing the synthetic full backup option.

Download Duplicacy Free

Duplicacy offers a free version that can be downloaded from their website. The free version provides many of the same features as the paid version, including incremental and synthetic full backups, retention policies, and offsite copies.

Duplicacy vs Acronis

Comparison of Features

Duplicacy and Acronis are both popular backup tools, but they have some key differences. Duplicacy offers incremental and synthetic full backups, retention policies, and offsite copies, while Acronis offers image-based backups, ransomware protection, and AI-powered backup.

Comparison of Pricing

Duplicacy and Acronis also differ in terms of pricing. Duplicacy offers a free version, as well as several paid plans, while Acronis offers a single paid plan.

Conclusion

Duplicacy is a powerful and versatile backup tool that offers a range of features to help individuals and organizations protect their valuable data. Its incremental and synthetic full backup capabilities, retention policies, and offsite copies make it an ideal solution for those looking for a reliable and efficient backup system.
