About this release

This release patches version 2.3.0.1 with fixes for a few issues that were discovered after the release.
This is the same as the 2.3.0.2 release but with a few additional fixes that were missed by the 2.3.0.2 release.

Reliability Fixes

This release optimizes the synthetic filelist creation process to improve performance significantly. Additionally, there are a few added failsafe checks to ensure syntehtic filelists are always valid.

We also fixed an issue with remote-file locking that could (ironically) cause database locking issues in some cases. And we fixed the S3 lock mode configuration to show the correct values.

Backend Fixes and Improvements

We fixed an issue where the SMB backend could incorrectly treat files as folders giving warnings when attempting to enumerate them. We also fixed a timeout issue for OneDrive where slow transfers could trigger an unexpected timeout.

The OneDrive for Business and SharePoint backends have been deprecated in favor of the Microsoft Graph backend, as the older backends relied on an API that is no longer supported.

We also made the Duplicati storage backend publicly available, so you can now use Duplicati storage for your backups. Duplicati storage is integrated with the Duplicati Console, so there is zero storage configuration needed on the client.

Platform and Restore Improvements

This release also features a new option --exclude-non-local-files that can be used to exclude files that are stored in the cloud, such as OneDrive, Dropbox, etc.

We also fixed an issue causing warnings when doing backups of the MacOS Photos folder, and improved some error messages to include more guidance on how to resolve them.
