2026-03-05 - 2.2.1.0_beta_2026-03-05 This release is a beta release intended for wider testing before being promoted to stable. This beta release contains all changes from the canary releases since the stable release 2.2.0.3 until ns including 2.2.0.105. Major Changes in this Release Database Schema Update Note: This update changes the Server database schema to version 11. The database tool can perform downgrades if needed. Multiple Backup Destinations This version adds support for configuring multiple destinations for a single backup job. This allows you to backup to multiple locations simultaneously, such as a local drive and a cloud storage provider. With multiple destinations, you can now configure a complete 3-2-1 backup strategy in a single job. After each completed backup, Duplicati will ensure that data is available on all destinations. A 3-2-1 backup strategy is where you have 3 copies of your data, 2 of which are on different media, and 1 of which is offsite/immutable. Remote Sources Remote sources are now easier to use with UI support and a prominent button on the source page. This version also adds support for using Box, Dropbox, OneDrive, and Google Drive as remote sources. Windows Folder Status Indicator Thanks to @AndyBodnar, this version adds a Windows shell extension that shows the backup status of folders with icon overlays. The feature is disabled by default but can be enabled with the option --enable-folder-status-service on either Server or TrayIcon. Once enabled, run the RegisterFolderStatusExtension.ps1 script to register the extension and see backup status in Windows Explorer. Google Workspace Backup This version adds support for backing up Google Workspace, including Gmail, Google Drive, Contacts, Calendar, and Chat. This is a proprietary module (source available) that requires a license to use in production. Without a license, testing is possible with up to 5 users. To prevent proprietary modules from loading, set the environment variable DUPLICATI_DISABLE_PROPRIETARY_MODULES=1 or delete files named Duplicati.Proprietary.* from your installation. Office 365 Backup This version adds support for backing up Office 365 tenants, including mailboxes, calendars, contacts, OneDrive, Planner, Tasks, Teams, Sites, and more. This is a proprietary module (source available) that requires a license to use in production. Without a license, testing is possible with up to 5 users + 5 sites + 5 groups. Full Disk Backup This version adds simple support for backup and restore of entire disks, including the MBR/GPT partition table. In this initial version, only Windows is supported, and the backup accesses the disk directly (no VSS). Support for Linux and macOS, as well as VSS support for Windows, is planned for future releases. Like the Office 365 / Google Workspace features, this is a proprietary module (source available). Full disk backup requires administrative privileges to access the disk directly. Full disk restore requires administrative privileges and requires that the disk is unmounted and not write-protected. Remote File Locking This release adds support for remote locking of files on supported storage providers (S3, Azure Blob Storage, Backblaze B2, iDrive e2, Google Cloud Storage). Locking protects backup files from being deleted or overwritten during a configurable retention period. To use the feature, set the advanced option --remote-file-lock-duration (e.g., 30D for 30 days). Each backend supports governance (lock can be removed in admin console) or compliance (lock cannot be removed) modes. Templating Engine for Reporting Thanks to @AndyBodnar, it is now possible to use a Handlebars template to format the report output, which is especially useful for crafting custom email reports. Synology Native Package The Synology native package has been re-developed to support Synology DSM 7.2 and above. The package installs as any other Synology package and uses integrated DSM authentication. Soft Delete Support A new option --soft-delete-prefix enables the soft-delete feature. When enabled, files are renamed/moved instead of being deleted, allowing lifecycle management rules to handle actual deletion after a retention period. Platform Updates

• .NET 10: The application now runs on .NET 10 for improved performance
• SQLite: Updated to use Microsoft.Data.Sqlite for better performance and async query support
• VSS Provider: Default VSS provider on Windows is now Vanara (AlphaVSS is no longer maintained) Database Encryption Changes This release adds a "default secret provider" for the current OS:
• Windows: Windows Credential Manager
• macOS: Keychain
• Linux: libSecret (Gnome Keyring), or commandline pass if available If no secret provider is configured, and a default secret provider is available, the database will be encrypted with a random password stored in the default secret provider. To opt-out, use --disable-db-encryption when starting the Server/TrayIcon. If database enncryption is already configured, or no default secret provider is available, nothing will change. Simplified S3 Provider Configuration The S3 provider configuration has been simplified by providing fewer options and only showing relevant endpoints. A whitelist of public S3 providers is included, and hostnames are shown in backup reports if in the whitelist. New Languages Added support for Hungarian, Czech, and Polish languages.
