Store securely encrypted backups on cloud storage services!

Duplicati is a free, open source, backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with:

   Amazon S3, IDrive e2, Backblaze (B2), Box, Dropbox, FTP, Google Cloud and Drive, MEGA, Microsoft Azure and OneDrive, Rackspace Cloud Files, OpenStack Storage (Swift), Sia, Storj DCS, SSH (SFTP), WebDAV, Tencent Cloud Object Storage (COS), Aliyun OSS, and more!

Duplicati is licensed under the MIT license and available for Windows, OSX and Linux (.NET 4.7.1+ or Mono 5.10.0+ required).

Download

The latest version of Duplicati is a beta version for the Duplicati 2.0 release.

Click here to download the latest Duplicati 2.0 beta release.

The beta release will automatically notify you of updates and allows you to upgrade with a single click (or command in the terminal). For even more bleeding edge access, check the latest releases or choose another update channel in the UI or on the commandline.

All releases are GPG signed with the public key 3DAC703D. The latest signature file and latest ASCII signature file are also available from the Duplicati download page.

Support

Duplicati is supported by an active community and you can reach them via our forum.

We have a great Duplicati manual that you can also contribute to.

Features

• 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.
• Integrated updater notifies you when a new release is out
• 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.
• Filters, deletion rules, transfer and bandwidth options, etc

Why use Duplicati?

Keep your data safe, store it far away, update your backup regularly! This is a simple rule but many backup solutions do not achieve that today. But Duplicati does!

Keep your data safe! Bad guys on the Internet seem to look for interesting data everywhere. But people do not want to see any of their private data revealed anywhere. Duplicati provides strong encryption to make sure that your data looks like garbage to others. With a well chosen password your backup files will be more safe on a public webserver than your unencrypted files at home.

Store your backup far away! The best backup is useless when it is destroyed together with its original data. Just assume that a fire destroys your office - would your backup survive? Duplicati stores backups on various remote file servers and it supports incremental backups so that only changed parts need to be transferred. This makes it easy to use a destination far away from the original data.

Backup regularly! The worst case is that your backup is outdated simply because someone forgot to make a backup at the right time. Duplicati has a built-in scheduler, so that it's easy to have a regular, up-to-date backup. Furthermore, Duplicati uses file compression and is able to store incremental backups to save storage space and bandwidth.

duplicati's Issues

Be more precise in obeying the volume and size limits

From [email protected] on February 26, 2009 13:19:01

The current implementation adds files, until the size limit is exceeded.
This means that the size limit will always be exceeded.

Files larger than a given threshold should be added in blocks, and the file
size checked before adding a block, to make sure the block would fit
uncompressed. This will produce more entries in the resulting file, and
requires some logic if there is a limit on the total size of the backup, so
a very large file can be backed up, even if its compressed size exceeds the
backup size limit.

Separate the GUI frontend, and allow Duplicati to run as a service

From [email protected] on February 26, 2009 13:27:46

If the user closes the Duplicati icon (or is not logged in), Duplicati will
not run. If Duplicati can run as a service (daemon on linux), these
problems will be solved.

The GUI should communicate with the service over an encrypted TCP link (or
possibly named pipes, if they are on the same host).

Use low system resources (memory) while idle

From [email protected] on March 13, 2009 15:57:55

I know, this is a delicate thing when talking about .Net development, but,
as Duplicati is supposed to be running all the time in Windows, either as a
tray icon or (in the future) as a service, it would be a great achievement
ot have it using as low system resources as possible.

Right now, I have it using 20MB or private memory (210MB virtual size),
which sounds like a lot for just being sat there in the icons tray.

Having only a tiered down service running on memory is an idea, which would
launch the application at scheduled hours.

Actually, separating the setup/settings GUI from a Windows service (ticket
#9) would help a lot in this sense.

Add a progress bar in the status window

From [email protected] on February 26, 2009 13:24:14

When Duplicati runs a backup, it is not possible to see how much of the
backup is currently processed.

By adding a progressbar to the status window, it will be possible to
estimate the duration, and current progress of the backup.

Figure out how to include files from multiple drives in a single backup

From [email protected] on April 07, 2009 20:18:06

The current setup requires a "root folder" where the file list is generated
from.

If the user wants to back up files on both the C: and D: drive, they must
use at least two backups.

A solution to solve this should be made.

Original issue: http://code.google.com/p/duplicati/issues/detail?id=48

Allow only one instance of Duplicati

From [email protected] on February 26, 2009 13:23:04

Duplicati only works with one instance open (due to the scheduler, and not
refreshing data from the database after load).

The current version allows the user to open multiple instances of the GUI,
which will create broken backups, if multiple instances try to perform the
same backups simultaneously.

Original issue: http://code.google.com/p/duplicati/issues/detail?id=6

Add option to store file metadata (ACLs, permissions, attributes, etc).

From [email protected] on March 12, 2009 15:47:32

On Windows, the DACL could be stored, and then re-applied after a restore.
On linux the UID/GID and permissions could be stored.

This would make the tool more attractive for enterprise uses.

Split Setup into Backup/Restore in the context menu

From [email protected] on March 09, 2009 17:56:26

This is my first ticket, so I'd like to write that I've just installed
Duplicati and it seems that it is exactly what I was searching for, keep
up the good work :-)

Anyway, here's the first minor thing that was not intuitive for me: once I
have set up a test backup, I tried to restore a file. It took me just a
couple of seconds to find it because there are only a couple of items,
however I think it would be more intuitive to have a separate item in the
context menu to restore files called "Restore" (for example).

Add option to exclude files larger than a certain size

From [email protected] on March 24, 2009 13:05:24

If the user inadvertedly drops a very large file, like a 1GB video-clip, it
will be backed up, but it takes a very long time.

If the user can set a threshold for file sizes, this can be prevented.

I know it is marked with TODO in the code, however I though I'd create a
ticket for it in case anyone was wondering why the command line version of
Duplicati doesn't work as expected.

The Duplicati.CommandLine.exe expects at least two parameters, otherwise
it throws an (unhandled) exception.
Either
"Duplicati.CommandLine.exe /?"
or
"Duplicati.CommandLine.exe --help"
doesn't work.

It would be nice to provide some basic help for this tool.

Make Duplicati compatible with Duplicity

From [email protected] on March 14, 2009 12:10:53

Duplicati should have a switch that toggles Duplicity compatibility.

To be Duplicity compatible, Duplicati needs to support tar/gz compression
and fragments inside those files. Such a flags should also switch to GnuPG
encryption.

Compating incrementals / Synthetic backups

From [email protected] on February 26, 2009 13:15:26

It should be possible to "compact" a series of incremental backups.
Compating should then create a single volume, consiting of all the
signatures as they would be if restored using the current chain. This
information should then be stored in a single file (if volume limit
permits). This will enable incremental backups to only download a single
file, and will thus make the incremental backup faster.

It should also be possible to specify a "compact-if-older-than" and
"compact-if-more-than-n-incrementals" so the backup will automatically
create the compact signature file, and not issue extra downloads of the
signature files.

From [email protected] on March 13, 2009 16:05:39

This is my vision for it, after reporting ticket #24... we could have the
following applications composing Duplicati:

• duplicati.exe : the application that effectively does the backup job. It
  would not be a bad idea to make it respond to command line arguments too.
• duplicati_gui.exe : the GUI application, used to setup and configure
  things. It should be a "launch and close" thing, not sitting in the memory.
• duplicati_service.exe : the Windows service that starts the backup jobs.
  It should be an extremely lightweight application, which simply fires
  duplicati.exe when needed (it's just a way of saying... it should do that
  in the .Net way of loading/unloading assemblies).

Add option to show actual files in a backup

From [email protected] on March 23, 2009 13:09:08

To diagnose problems with backups, it would be usefull to be able to list
the files present in a given volume. The current "list-current-files" shows
all the files that would be restored, but this function should only show
files that are present in a given signature file, possible only for a given
volume.

The output should look like:
full/incremental;fragmentsize;filename

The wizard can expose this by allowing the user to right click a date in
the restore dialog.

Fetching filelist on restore seems to take too long when the signature cache is enabled

From [email protected] on March 16, 2009 13:20:49

When the signature cache is enabled, it should not be required to download
anything but signatures, but it seems that files are actually downloaded.

The status window is incorrectly placed in linux

From [email protected] on April 07, 2009 22:44:29

Under ubuntu, the "working area" has a top and bottom toolbar. Duplicati
thinks that both are at the bottom (like they would be in windows), and
places the window at the wrong position.

If possible the actual placement of the tray icon should be read, and the
window placed as close to it as possible.

The "toolwindow" looks ugly in linux, and should not be used.

Deal with inacessible directories

From [email protected] on March 29, 2009 20:12:47

If a folder is unavalible, it is assumed to be so, due to insufficient
filepermissions, and is skipped.

However, if the error is temporary, the files that were previously in that
folder, will be marked as missing, and thus marked as deleted, making them
hard to recover.

This should be reconsidered and a solution made before the initial release.

Improve FTP dialog

From [email protected] on August 05, 2008 22:47:57

The FTP dialog's "test button" does not give intuitive results.
It should be possible to create the remote folder, if it does not exist.

Add option to allow local copies of signature files

From [email protected] on March 07, 2009 14:02:32

The current method always downloads the signature files for each
incremental backup. It should be possible to keep a cache of signature
files locally, so these can be retrieved without downloads.

Special care must be taken to ensure that the local copy is not stored
before the remote copy is fully stored.

This will not affect restores, as they do not rely on signature files.

Deal with filesystem limitations

From [email protected] on March 28, 2009 23:37:15

Current setup of Duplicati uses the default filenames that are long, and
includes the : character.

This does not work well, if the destination host runs MacOS or Windows.
There should be an option to use an alternate timeseperator char, and short
filesnames.

Figure out if this should be on each backend, or a common place.

Improve the file selection dialog

From [email protected] on March 11, 2009 22:05:36

If the user has complex filters setup, the file GUI in the wizard can
potentially destroy those filters, if it incorrectly identifies the filter
setup as being a simple checkbox selection.

Modified files count as if they were new files as well

From [email protected] on February 26, 2009 13:25:58

When inspecting the backup log report, modified files appear as if they
were added, in addition to being listed as modified.

Add a companion tool to work with files

From [email protected] on April 07, 2009 16:05:49

The backend system in Duplicati is fairly flexible, and some backends (like
S3, WEBDAV) have "official" user interfaces that I consider poor.

Using the backends present in Duplicati, it should be easy to create a tool
to work with such backends.

Later on, an explorer plugin could make any backend avalible as a remote
storage disk.

Unhandled exception with Setup Wizard

From [email protected] on April 04, 2009 10:58:20

What steps will reproduce the problem? 1. Open Setup Wizard (either first start of Duplicati or click Setup in
tray menu)
2. Click Setup in tray menu with Setup Wizard window still open

An unhandled exception will occur:

System.InvalidOperationException: Form that is already visible cannot be
displayed as a modal dialog box. Set the form's visible property to false
before calling showDialog.
--- What is the expected output? What do you see instead? Setup Wizard window should be brought to the foreground if already open. What version of the product are you using? On what operating system? Version: 1.0 beta 3
OS: Windows XP

Add a WEBDAV backend

From [email protected] on March 14, 2009 12:25:37

Since WEBDAV is just a smart way of issuing HTTP requests, it should be
very easy to support this in Duplicati.

Add putty and gnupg to the installer

From [email protected] on April 07, 2009 20:12:08

If the license permits it, putty and GnuPG should be added to the installer
as optional items.

If the license does not permit so, a link should be provided so they may be
downloaded manually.

Currently they work if they are installed from their respective installers.

Fix the restore file selection

From [email protected] on April 06, 2009 14:53:28

The file selection dialog has some usability issues if the tree has a deep
folder structure.

The code should just look at checked leaf-nodes, and checking a top-node
should toggle child nodes.

More options

From [email protected] on March 07, 2009 14:00:03

An option to specify custom extra commands to Duplicati would make it
easier to add experimental options, without having to fit it into the GUI
interface immediately.

Specifically, an option to specify the "time-seperator-char" and
"short-filenames" switch would be nice.

Wishlist: Cloud Files backend

From [email protected] on April 03, 2009 19:09:20

Cloud Files would be a nice addition to Duplicati. http://www.mosso.com/cloudfiles.jsp Please, let me know if this might be interesting, and I would be happy to
work on an account for development.

Kind Regards,

Add filter option to backups

From [email protected] on July 15, 2008 21:31:23

Duplicity supports both include and exclude filters for filenames.
These should be useable in Duplicati, and preferably there should be an
option to select a folders to exclude, and pehaps a "Include all except
selected" or "Include only selected".

The progress bar does not correctly display all labels if opened after the process has started

From [email protected] on March 12, 2009 17:18:51

The progress bar in the status window does not correctly display all labels
if opened after the process has started. This is due to the current setup,
where submessages and messages are in the same field.

Test and release a Mono compatible version (for Linux/Mac)

From [email protected] on March 14, 2009 12:14:02

The current code should run well on Mono, and under Linux/Mac, but it
should be tested, and a binary package should be released.

E-Mail notifications

From [email protected] on March 14, 2009 14:44:16

Introduce in the settings and setup process a way to configure e-mail
notifications with the results of backup jobs.

The configuration dialog could have the following fields:

• SMTP Server
• SMTP User Name
• SMTP Password
• Sender's Address
• Target Addresses (more than one, separated by comma)
• E-Mail Subject Prefix
• Send on Success (checkbox)
• Send on Failure (checkbox)
• Test E-Mail (button to test these settings)

Considering that Duplicati is to be run silently in the background, this
feature brings too benefits:

• I can be notified by e-mail on failure, so I know that I need to check it.
• The IT department of my company can be notified about my backup, being
  sure that things are working properly at my side.

The e-mail message could even include a summary about the backup job.

Skip signatures with invalid hashes

From [email protected] on March 12, 2009 17:17:43

The current method for dealing with broken hashes is to just abort.
However, if the signature file is merely discarded, it will appear as if
the file was never backed up, and will thus be part of the next backup set.

The user should probably be notified of the problem in some way.

Add an explorer plugin

From [email protected] on March 24, 2009 15:22:34

It would be nice if Duplicati could register with Explorer and add overlay
icons like TortoiseSVN does, to indicate the status of the individual
files, eg: excluded, backup up, modified, new.

Some logic will be required if the files are touched by multiple backups.

Improve speed of Duplicati

From [email protected] on March 16, 2009 16:45:36

The current implementation uses regular expressions for filtering files.

This can be improved by only using regular expressions where required, and
faster matching for simpler expressions.

Use the OS Shadow functions where avalible

From [email protected] on March 12, 2009 14:52:36

If the user is saving a file at the excact time the backup is reading it,
the result may be a partially written file, which is most likely useless.
If the application uses multiple interdependant files, this may even be worse.

Windows and Linux offer a "Shadow" system, which is like a "copy-on-write"
method that allows the backup application to "freeze" the filesystem, so
the backup is excactly like the files were at the time the backup was
initiated. The "Shadow" system then ensures that the applications can run
as normal, and when a file is written, a shadow copy is kept for the backup
process. All shadow copies are then removed when the application notifies
the OS that the operation is completed.
