Duplicati 2.3.0.0 (64-bit)

What's new in this version:

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 encryption 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. Thanks to all translators!
- Quality of Life Improvements:
- The commandline-inside-the-UI feature now saves its state when navigating back
- Added "Edit as text" option for source paths and filters
- Linux AppImage builds are now available
- Auto VSS on Windows when user has Administrator privileges (SeBackupPrivilege)
- SSH-Agent support for SSH backend
- Support for macOS Photos backup with --photos-handling option
- New UI is more small-screen friendly

Notable Bugfixes:
- Fixed issue with invariant formatting causing crashes during backup
- Fixed dry-run to strictly not touch data
- Fixed --changed-files option to not introduce extra dangling file entries
- Fixed purge operation size calculation and added --reduced-purge-statistics option
- Fixed index file corruption issue where index files could become incomplete over time
- Fixed restore flow to reduce temporary space usage (configurable with --restore-volume-cache-hint)
