2025-08-19 - 2.1.1.101_canary_2025-08-19

==========

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

# Changes in this versions

This version has an update to the restore process that reduces the amount of temporary space used during restores.

With the option `--restore-volume-cache-hint` it is now possible to choose how much size to use, and the dafult is 4GiB.

A problem with ngclient saving sizes with the default multiplier was fixed, and an improved list of destinations was added.

The breaking change in 2.1.1.100 with the `--allow-empty-source` was tested and found to have too many negative issues, so it was inverted to be `--prevent-empty-source` such that it is possible to turn it on, but it does not by default fail if the source folder is empty.

For Debian packages, the libICU package is now a recommended dependency and will not prevent installing the package.

A pre-install script warns if no libICU package was found, and shows how to run without libICU present.

## Detailed list of changes:

- Fixed an issue with null values on Sharepoint mounted folders

- Improve support for libICU on Debian

- Fixed a case where testing would fail on a missing hash value

- Added support for limiting the usage of local temporary disk space during restore

- Inverted `--allow-empty-source` to `--prevent-empty-source` (opt-in)

- Fixed an issue with S3 backend reading stream twice

- Lowercase S3 AWS Client content hash for better compatibility with other providers

## ngclient changes:

- Improved searching for destinations

- Resolved some issues with colors not being applied

- Fixed an issue with non-default size multiplier causing invalid values to be saved

- Streamlined suffixes for sizes to be the same

- Removed support for picking `bytes` as the multiplier

- Fixed issue with livelog page requesting invalid data when disabled

2025-08-08 - 2.1.1.100_canary_2025-08-08

==========

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

# Changes in this versions

This build adresses an issue with timeouts on B2 uploads, along with a number of minor fixes.

There is a breaking change in that Duplicati will now consider an empty *source* folder as an error, unless you specify `--allow-empty-source`. This is done to avoid common mistakes where a folder was supposed to be mounted but was not.

The Docker images have been overhauled and now supports running with a custom UID/GID combination.

The login flow has been secured slightly and now features an extra nonce value that is required on requests. If you have custom code authenticating with Duplicati this is a breaking change.

Finally, there is now also an option to log internal HTTP requests to the log for tracing and debugging.

## Detailed list of changes:

- Fixed commandline test command issuing a warning

- Fixed erratic timeouts on B2

- Corrected reported timeouts in BackendTester

- Fixed some quoting of SQLite queries

2025-07-09 - 2.1.0.123_canary_2025-07-09

==========

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

This version is nearly identical to 2.1.0.121 which has a startup crash.

This version is nearly identical to 2.1.0.122 which has an issue with detached TrayIcon.

# 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

### Updated in 2.1.0.122

2025-06-24 - 2.1.0.120_canary_2025-06-24

==========

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

The intention is to tap this release as an experimental release if no significant issues are uncovered.

# Major changes in this version

This release is mostly fixing minor issues reported from 2.1.0.119, with only a few changes that could impact backups.

A significant amount of fixes has been completed for ngclient.

The repair flow can now detect and fix cases where a file or folder has been assigned no metadata.

Since the codebase does not support this, the current fix is to assign an empty metadata block if possible, and otherwise use the smallest metadata block.

The Test output no longer reports failures on index files that were fixed during the test process.

The destination picker UI in ngclient has been reworked in multiple ways, providing a more robust experience with the Test button and results being more prominent.

The restore flow and file picker has been updated to fix a number of issues with files and folders that have the same prefix.

Some issues with the picker not having the correct visual representation of the state.

2025-05-29 - 2.1.0.119_canary_2025-05-29

==========

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

The intention is to tap this release as an experimental release if no significant issues are uncovered.

# Major changes in this version

## Index file corruption fixed

This update fixes a long-standing issue with index files being incomplete over time.

The effect of this is that the recreate database step takes much longer than expected.

With this update the index files no longer loose information during the compact step.

To remedy existing data, the test method can now be run and only check index files (`--full-remote-verification=indexesonly`).

By default, any defective index files that are found will be replaced with correct versions, so simply running the test command with a large sample size will fix the backup.

## Suppress warnings

A new option is added that can change warning messages to information messages, so the warnings no longer generate notifications.

The file access errors are now better grouped so it shows if the error is a permission error, a locked file error and others.

With the suppress feature it is possible to suppress one or more categories of these warnings.

## Better backend Test

The test feature has been updated to now check for write permissions, instead of just listing the remote folder.

For ngclient, the Test check now uses this extended check to inform the user if there are files in the destination folder.

This shows a warning if creating a new backup pointing to a folder with existing data, and a warning if attempting to restore from a folder with no files.

If the write part fails for a test during the restore flow, this is not treated as an error in ngclient.

## Auto VSS on Windows

If the user has Administrator privileges (`SeBackupPrivilege`) VSS is now set to `Auto` by default.

## Updated backends

Updated the backends: Jottacloud, Google Drive, Google Cloud Storage, Dropbox, and OpenStack.

Removed the Sia backend as the current implementation is not compatible with the pending hard-fork.

## No throttle for the file backend

The file backend is now excempt (by default) from throttle settings via `--throttle-disabled-backends`.

Individual backups can set `--throttle-disable` to opt-out of throttling.

## Disabling reported options on Webserver

The ngclient is using the reported options to figure out what features can be enabled.

This can now be configured with `--webservice-disable-api-extensions` so websocket usage can be disabled, among others.

## ngclient updates

A number of fixes and additions are made to ngclient, including a new grid-view for users with many backups.

## Database version upgrade to v17

The local database is again upgraded with an index changes performance.

The bundled `Duplicati.CommandLine.DatabaseTool.exe` / `duplicati-database-tool` can downgrade databases.

Since the change is only index addition, there is no data loss on downgrades.

2025-05-12 - 2.1.0.118_canary_2025-05-12

==========

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

# Major changes in this version

This version has a number of minor fixes and a major rewrite of the the "repair" command.

The logic for the "repair" command is that it should be possible to recover loss of `.dblock` files, if the data is still present locally.

This logic has been fixed in multiple ways and now also supports recovering data, even if no individual `.dblock` volumes can be fully recovered.

In this case, the repair will recreate as much data as possible in new `.dblock` files, and configure it so as many files as possible are available.

The `purge-broken-files` can be used after repair has failed to recover eveything, and will only purge the files that were lost.

The `purge-broken-files` command has also been updated to support using incorrect metadata, such that files are not purged if they are only missing metadata.

There are again numerous fixes to ngclient, including some faster browsing of restore contents, and better remote validation of folder contents.

The UI now supports a number of different languages.

## Database version upgrade to v16

The local database is again upgraded with two index changes for correctness and performance.

The bundled `Duplicati.CommandLine.DatabaseTool.exe` / `duplicati-database-tool` can downgrade databases.

Since the change is only index addition, there is no data loss on downgrades.

## Detailed list of changes:

- Support `CACHEDIR.TAG` as a default exclude file marker

2025-04-25 - 2.1.0.117_canary_2025-04-25

==========

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

# Major changes in this version

This update adresses a few edge cases where a crash or other problem could cause the database to become out-of-sync.

Support for "archived" files makes Duplicati more compatible with life-cycle rules, that moves files into longer-term storage.

The support is currently added for S3 and Azure Blob Storage, and works by not attempting to test files that are archived.

Compacting still needs to be turned off if using life-cycle rules where files are inacessible.

The version of the local database is updated to v15 to support the archive timestamp.

A new tool is added `Duplicati.CommandLine.DatabaseTool.exe` / `duplicati-database-tool` which can downgrade databases.

The tool can be used prior to installing an older version, and will downgrade the database to the previous version (14 in this case).

The tool can target individual databases, but will default to take all databases in the storage folder.

Throttle options were broken with a recent update. The fixed version now shares the throttle between all transfers.

Previously, setting a 10kb/s limit would cause each individual stream to be capped to 10 kb/s, but now the setting will throttle the combined upload speed (each stream gets a fraction of the limit).

2025-03-15 - 2.1.0.111_canary_2025-03-15

==========

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

# Major changes in this version

- Restore improvements

This version has a few tweaks to the new restore flow that makes it more robust.

- Improved validation

To safeguard against internal errors, there is now a more strict validation before performing cleanup.

The new logic checks if the previous operation failed and will only automatically repair the remote if this is the case.

The repair command bypasses this check and can repair the remote regardless.

If the previous run was fully completed, any leftover remote files are now treated as an error.

Additionally, operations that does not change remote state (list, test, restore, etc) will not repair the remote state, but just verify that it is working for the requested operation.

- Updates to ngclient

Multiple updates to ngclient: improved auth flow, searchable menus, Windows filesystem support, restore from configuration, and more.

# Potentially breaking changes (from 2.1.0.109)

- Location of data folder has changed in some cases, refer to previous release for details

- Permissions are now applied to the data folder, refer to previous release for details

- New user interface, `ngclient` is the default; there is a button to switch between the two

## Detailed list of changes:

- Reduced number of samples taken for testing

- Improved restore flow

- Improved error handling for Azure Blob storage

- Improved help text for remote synchronization tool

- Implemented more rigorous validation and safeguards for failed backups

- Better support for IPv6 and unmapped localhost scenarios

- Added check to avoid block sizes that are the same or less than volume size
