Cyberduck 7

With Cyberduck 7 we introduce the possibility of a multi-segmented download. Multi-Segmented downloads offer the functionality to download one file over several connections. This has the advantage that some files can be downloaded faster and the download process is less error-prone.

In previous versions of Cyberduck, there was only the possibility to run downloads over a single serial connection, the multisegmented download feature multiplies the connections making a parallel download process possible. The following diagram visualizes the two types of download described.

You can expect at least a doubled download speed if you use the multisegment download functionality. Some additional time is required to concatenate the downloaded segments after the download itself is complete. We have collected the following data in download tests with downloads from Amazon S3 and a Minio server running locally.

Mountain Duck 3

Work Offline with Smart Synchronization

Version 3 adds a smart synchronization feature to add offline support. Files are synchronized to the local disk when opened to allow offline usage and changes are uploaded in the background as soon as a connection is available. Dropbox like experience with your preferred on-premise enterprise storage or cloud storage. With the additional option to choose which files and folders are available for offline use. Other files are visible but only stored as placeholders. These do not take up disk space on the computer and are downloaded on demand only.

Edit files Offline and upload changes when connectivity to remote server is restored.

Badge Icons

Badge icons in the Finder and Windows Explorer indicate the sync status of files – easily assess if the file is only available when online or is synced to your computer for offline editing. Synchronization with the remote storage is paused and resumed automatically depending on your network connection. The application icon in the system tray animates when a background transfer is currently in progress.

Upgrade

Mountain Duck 3 is a paid upgrade. Existing customers get an upgrade discount between 40% and 100% depending on the date of purchase. Please upgrade your license before updating.

Sharing Large Files

You want to grant one or several people temporary access to large files? Email is not an option and providers offering a web interface are costly, limit the file size or tend to be unreliable. Cyberduck or Mountain Duck in combination with cloud storage providers allows you to share files without relying on a third-party website.

Auto Expiring Links

With Cyberduck or Mountain Duck and those cloud storage providers, you can share links with third parties that expire after an hour, days or months. Between the protocols, the expiration time of the shared links may vary. Contrary to other solutions there is no restrictions on bandwidth or the number of downloads.

Supported Providers

In the following section, you will find a short guide on how to share large files with Amazon S3, Microsoft Azure, Dropbox or OpenStack Swift cloud storage providers.

Step by Step

  • Open Cyberduck or Mountain Duck and connect to your Amazon S3, Microsoft Azure, Dropbox or OpenStack Swift bookmark.
  • Navigate to or upload the file you want to share
  • Right-click on the file, choose the option Copy URL in the context menu and click on the Pre-Signed URL (within Dropbox it is named Temporary URL) with the wanted expiration time. In Cyberduck the same option is available in Edit → Copy URL→ Signed URL. Share the link with anyone you want to give access to.

Accessing OneDrive & Sharepoint

The number of different possible options for cloud storage provided by services available from Microsoft Office 365 is confusing and merits some further ado. There are two services available from Microsoft – OneDrive and SharePoint – which are hidden in a diversity of different packages. SharePoint is a cloud storage service which is only integrated in business packages while OneDrive is existing for personal and business usages. Every person who has a Microsoft Account does have access to the personal version of OneDrive. You can detect if you have a personal or business profile by looking at the email address. If you have a business profile the email address contains onmicrosoft.com.

In the following chart an overview of the most common business profile packages and whether the packages contain OneDrive, SharePoint or both is shown.

Sharepoint Online

Cyberduck and Mountain Duck support OneDrive in personal and business edition as well as SharePoint through the default bundled connection profiles Microsoft OneDrive and Microsoft SharePoint. It doesn’t make any difference if you are using OneDrive personal or business there is only one profile that works for both. To connect to OneDrive or SharePoint with Cyberduck or Mountain Duck you have to create a corresponding bookmark which will connect to the services via Microsoft Graph.

Connecting to OneDrive Personal and Business

  • Choose the profile Microsoft OneDrive.
  • Type in the Username field your account email address and connect to the bookmark.
  • A window appears and prompts for an authentication code. Alongside with the authentication code prompt, a web browser window should open with the login page of Microsoft. Log into your account in the web browser window and copy the afterward appearing authentication code into the field in the authentication prompt window.
  • If you are using Cyberduck a browser window will appear. If you are using Mountain Duck Windows Explorer or Finder are opened revealing your OneDrive.

Connecting to SharePoint

  • Click on “New Bookmark” if you using Mountain Duck or on the “+” symbol in the browser window if you using Cyberduck to create a new bookmark.
  • Choose the previously installed profile ​Microsoft Sharepoint Document Library or the bundled profile Microsoft SharePoint.
  • Log in with your *.onmicrosoft.com account to login.microsoftonline.com to connect to your SharePoint document library. If you want to connect to SharePoint online you have to use your OneDrive personal account.

More information can be found in the Help Wiki for both OneDrive and Sharepoint.

Encrypt your Dropbox

Mountain Duck and Cyberduck allow Cryptomator client-side encryption of your data which is missing in Dropbox and all other popular cloud storage solutions. You will find a description of how to use Cryptomator Vaults in Dropbox and access your documents from your computer and mobile in the following sections.

Encrypt your data with Mountain Duck and Cyberduck

  • Connect to your bookmark and navigate to the location where you want to store your secured data.
  • Right-click on white space and choose New Encrypted Vault in the context menu.

  • As described in the appearing window enter a name for your encrypted folder. Afterward, choose a password and confirm it by retyping it in the last field.

  • Double-click on your newly created Vault and unlock it by typing the password into the corresponding field.

  • The Vault opens. Now you can create or copy the documents you want to secure into the Vault to encrypt them.

Access your encrypted data with the Cryptomator app on your mobile.

  • Install the Cryptomator App on your mobile (IOS, Android).
  • Tab on the plus symbol and choose the option Add existing vault.
  • To open the previously created Cryptomator Vault choose the cloud service Dropbox, log into your account and navigate to the Vault.
  • Open the Vault folder and select the masterkey file which is named masterkey.cryptomator. After that, the app should show automatically the landing page of the Cryptomator app with the previously selected Vault pinned.
  • Tab on the pinned Vault and type the password into the corresponding field. The Vault should open right after you have unlocked it with the password and you have access to your secured data.

This process does not only work with Dropbox but with any other connection supported in Cyberduck and Mountain Duck. You can find more information on Cryptomator support in our wiki.

Connecting using AssumeRole from AWS Security Token Service (STS)

Instead of providing Access Key ID and Secret Access Key, authenticate using temporary credentials from AWS Security Token Service (STS) with optional Multi-Factor Authentication (MFA), making Cyberduck and Mountain Duck more friendly to enterprise deployments. You will need to install the custom connection profile S3 (Credentials from AWS Security Token Service) available from our website.

Our implementation to obtain temporary credentials is interoperable with standard AWS CLI configuration in ~/.aws/credentials. Refer to our wiki for documentation.
