Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).
Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes.
Duplicati is licensed under LGPL and available for Windows and Linux (.NET 2.0+ or Mono required). The Duplicati project was inspired by duplicity. Duplicati and duplicity are similar but not compatible.
- Duplicati uses AES-256 encryption (or GNU Privacy Guard) to secure all data before it is uploaded.
- Duplicati uploads a full backup initially and stores smaller, incremental updates afterwards to save bandwidth and storage space.
- A scheduler keeps backups up-to-date automatically.
- Encrypted backup files are transferred to targets like FTP, Cloudfiles, WebDAV, SSH (SFTP), Amazon S3 and others.
- Duplicati allows backups of folders, document types like e.g. documents or images, or custom filter rules.
- Duplicati is available as application with an easy-to-use user interface and as command line tool.
- Duplicati can make proper backups of opened or locked files using the Volume Snapshot Service (VSS) under Windows or the Logical Volume Manager (LVM) under Linux. This allows Duplicati to back up the Microsoft Outlook PST file while Outlook is running.
- We added support for long filenames under windows, so that you can now backup large hierachies of folders and files with lengths names.
- Duplicati now pauses when the computer wakes up from hibernation to give the system some time to calm down before the backup sources are parsed for changes.
- Symbolic links and NTFS junctions are now supported. In the advanced options under "symlink-policy" you can now specify how symboloc links are handled: store|follow|ignore.
- It is possible to exclude files based on their attributes. You can exclude e.g. hidden files or system files from your backup. The advanced option for this is called "exclude-files-attributes".
- VSS under Windows XP got a speed boost.
- The Tonido backend is now supported with the WebDAV backend.
- We also updated the German and French translations (French was broken in 1.3.2).
Fixed: German translation updated ( issue #657 ). We received a few improvements and added these now.
- Fixed: Unable to translate Unicode character \uDC63 at index 72 to specified code page ( issue #480 )
- Fixed: Only single volume uploaded (introduced in build 1388 and fixed in r1437 and r1438), issue #692
- Fixed: Infinite number of empty volumes created if last file spans volumes (introduced in build 1348 by r1437), issue #693
- Fixed: workaround for crash that occurred after backups were completed (r1452)
- Fixed: handling of invalid file timestamps for S3 (r1450)
- Fixed: Upload issue with Google Drive ("Failed to upload file"), issue #637
- Fixed: Donation link lead to Danish page (r1388). This is now in English. Feel free to try that out and see if it stays English when you make a donation ;-) If you do not like Paypal, you can also send Bitcoin. Our wallet is 1ADgoUoE9uN725Ypeh9M9WTKFLJzfWWMBh
