We have made available a feature in Cyberduck 7.6 and later to restore files from Glacier storage class in S3. You can temporarily restore files from Glacier using File → Restore for files with the storage class set to Glacier. The file will be restored using standard retrieval and expire in 2 days after retrieval. Restoring takes some time and attempting to download an item not yet restored will lead to an error *The operation is not valid for the object’s storage class. *

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.
| AWS EC2¹ | Local System² | |
| Regular Download | 20 MByte/s | 200 Mbyte/s |
| Segmented Download | 40 Mbyte/s | 1 GByte/s |
¹ AWS EC2: T2.Medium against a regular S3 endpoint
² Local Minio S3 Server feeding data from local NVMe-PCIe-SSD
The described feature can be turned on or off in Preferences → Transfers → General → Downloads.

Refer to the full changelog for many more enhancements and bug fixes.

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 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.

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.

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.
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.
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.
