Duplicity

Duplicity provides encrypted, bandwidth-efficient backups by producing encrypted tar-format volumes and uploading them to a remote or local file server. It uses the rsync algorithm for space-efficient incremental archives and GnuPG for security.

Key Features

• Encrypted & Signed: Backups are safe from spying and modification using GnuPG.
• Bandwidth Efficient: Only transmits changes since the last backup using the rsync algorithm.
• Incremental Archives: Saves space by storing only the parts of files that have changed.
• Multiple Backends: Supports a wide range of storage services (S3, Azure, B2, Google Drive, etc.) and protocols (SFTP, SCP, FTP, etc.).
