Duplicacy

Duplicacy is an open-source backup software that supports incremental backups to many cloud storage providers. It encrypts and compresses data for efficient storage and transfer. Key features include data deduplication, version control, backup retention policies, and command line interface.

What is Duplicacy?

Duplicacy is an open-source command-line backup tool designed for efficient incremental backups. It supports a variety of storage backends including major cloud providers like Amazon S3, Google Cloud Storage, Microsoft OneDrive, and Dropbox.

Some key features of Duplicacy include:

  • Strong encryption using AES-256 to secure backup data
  • Data compression and deduplication to minimize storage requirements
  • Version control of backups to facilitate restores
  • Custom retention policies to automate deletion of old backups
  • Command line interface for scripting and automation
  • Speed comparison to determine the fastest storage providers
  • Parallel uploads and downloads to accelerate transfers

Duplicacy is implemented in Go language which makes it fast and memory efficient. It works by splitting files into smaller chunks, uploading the chunks, then maintaining references to these chunks. This way, only modified chunks need to be transferred during subsequent backups.

Duplicacy supports backups for Windows, macOS, Linux, FreeBSD, and Solaris operating systems. Its data format is open and documented so the backups can be accessed without Duplicacy if needed.
