2.1.0.121_canary_2025-07-07

This release is a canary release intended to be used for testing.

EDIT: A bug in this version will prevent it from registering notifications from the UI, please use a later version.

Major changes in this version

This version introduces a new SQLite library, a new VSS provider, and some minor bugfixes.

SQLite update

This version has changed the SQLite library from the previous System.Data.SQLite library to using Microsoft.Data.Sqlite.
This update was quite invasive, as the new SQLite library does not support positional arguments in SQL queries, which was used extensively in the Duplicati codebase.
With the update we see measurable speedups across all queries, and we are producing an article that describes our findings.
The update also bumps the SQLite library to use the latest available version and makes all SQLite queries async and cancelable, making the stop commands more responsive.

New VSS provider supprt

The AlphaVSS library that is used for creating VSS snapshots is no longer being maintained.
This version now defaults to using the Vanara API layer to call the Windows VSS API and create snapshots.
Like before, this still requires the VC++ Redist to be installed.
For now, it is still possible to use AlphaVSS by setting --snapshot-provider=AlphaVSS.
Note that neither works on ARM64 as Windows is lacking libraries and tools for native ARM64 snapshots, only --snapshot-provider=WMIC works on ARM64.

Bugfixing for ngclient

A number of reported compatibility issues with ngax has been fixed in this version.

Detailed list of changes:

Commandline UI expands environment variables
The file:// backend is no longer throttle exempt by default
Fixed issue with TrayIcon not outputting help text in all cases
No longer retains SeBackupPrivilege after testing for permissions
Refresh token lifetime can now be configured
Fixed multiple issues with kill signals not stopping the process
Secret provider now correctly applied for all TrayIcon arguments
Updated SQLite library to use Microsoft.Data.Sqlite packages instead
Default VSS provider is now Vanara
Hide options that are not supported on the current OS
Fixed backup schedule order after multiple missed backups
Fixed an issue with Google Drive backend not creating folders
Updated all localization, thanks to all translators

Ngclient changes:

Fixed issue with -- option prefixes not being matched
Updated all localization, thanks to all translators
Fixed issue with en-GB not using 24h time format
Fixed issue with editor for GCS not having a path field
Fixed issue with editor for B2 introducing extra / characters
Fixed supporting -s postfix for backends for backwards compatibility
Fixed case-insensitive support for boolean and enumeration options
Custom arguments is now a two-line input

No GUI when launching. No warning. When I run Duplicati.GUI.TrayIcon.exe via CMD, this comes up:

No database encryption key was found. The database will be stored unencrypted. Supply an encryption key via the environment variable SETTINGS_ENCRYPTION_KEY or disable database encryption with the option --disable-db-encryption

Thanks for reporting. I am looking into it. EDIT: I can reproduce.

PR ready that fixes it:

This PR fixes [issue 1715](https://github.com/duplicati/duplicati/issues/1715 )…. Essentially, the fix moves the root comparison from SQL to C#, converting a `O(n^2)` comparison to an `O(n)` one. This is done by exploiting the fact that the paths returned from the query are sorted, so we don't have to look at all of the entries, when comparing to whether each new path contains a potential new root.

Many new UI Destination fields usually (but not always) turn a space into a %20.
This can happen during Import or just typing. I found this on Folder path first, so:

import percent-encodes spaces in Path on server #320

It’s also on Server and Bucket. Others such as Username and Password are OK.
This makes ngclient hard to use. One can’t even paste in Path for a workaround.

Oddly Test destination works (didn’t it get improved?), but Verify sees no files

Edit target URL and changing %20 into spaces also doesn’t work. %20 returns.

kenkendk · July 7, 2025, 6:39pm

Thanks for reporting. I think we need to fix it again for the server+path pairs
