This PR adds support for using Box, Dropbox, GoogleDrive, SharepointV2, MicrosoftGroups, and OneDrive as remote sources.
For GoogleDrive, this requires full permissions and not just the regular OAuth access token.
Also extended S3 and SMB to actually look up a file if requested, which makes it possible to rely on the backup exclusion files, even when using remote sources. (SSH/SFTP does not currently support this).
This PR updates existing backends to implement the `IRenameEnabledBackend` interface, allowing for more efficient file renaming operations. The implementation varies by backend, with some using native rename operations and others falling back to copy-and-delete patterns.
This PR removes the `OAuthContextSettings` class, and makes the `--oauth-url` option available on each backend that uses it, so it can be configured as part of the destination.
To assemble everything related to configuring OAuth, the code was moved to the `AuthIdOptionsHelper`, such that the usage can be shared between implementations.
This PR also adds the option to set the default OAuth url from the environment variable `DUPLICATI_OAUTH_SERVICE`.
The server can then be set in the following locations (most important last):
- Environment variable
- Server-wide advanced settings
- Backup job advanced settings (or commandline)
- Destination url
This PR is the final change, where all backends are now purely implemented with async interfaces.
The code changes here replace the LIST call with an async version. This affect all backends (and then some) but the changes are mostly mechanical rewrites of the code.
In many places, the backeds were already prepared for async output, in other some glue was needed.
To reduce the scope of this change, some backends simply report a synchronous result as an async list.
* Added options to insert delays in backend tester
* Added wait delays to Azure and GoogleDrive to see it the CI is more stable with small delays
* Added more debug output to the backend tester
* Fixed dropbox reporting OAuth quota errors, when it is likely Dropbox API quota errors
* Implemented exception detection on AzureBlob backend
* Also showing sleep times in output
* Fixed a bug with the dropbox quota response
* Fixed error message to report correct number of files
* Fixed suppressed warning
