Duplicati is an open-source backup client that securely stores encrypted, incremental, compressed remote backups of local files on cloud storage services and remote file servers. Duplicati supports not only various online backup services like OneDrive, Amazon S3, Backblaze, Rackspace Cloud Files, Tahoe LAFS, and Google Drive, but also any servers that support SSH/SFTP, WebDAV, or FTP.
Duplicati uses standard components such as rdiff, zip, AESCrypt, and GnuPG. This allows users to recover backup files even if Duplicati is not available. Duplicati is free software, originally released under the terms of the GNU Lesser General Public License (LGPL), it has been under the MIT License since March 2024. This changeover took place as part of the launch of Duplicati, Inc. and the commercial use of the Duplicati base.
Duplicati is written mostly in C# and implemented completely within the CLR, which enables it to be cross-platform. It runs well on 32-bit and 64-bit versions on Windows, macOS and Linux using either .NET Framework or Mono.
