This fixes the restore issues as all sources will now appear as if they were originally part of the source file system.
The backend implementation has now been simplified so the backends only return names of entries with no path information. Most backends already do this, but the S3 backends did not, so this was fixed as well.
This also clears up the interfaces, so the backend does not know about the `ISourceProviderEntry`. All mapping is done by the `BackendSourceProvider`, making it simpler to support other backends as sources.
Made the SMBShareConnection slightly more robust.
Introduced v2 List API to S3 backend, currently it retains v1 as the default.
Changed S3 backends to not recurse, potentially making smaller listings. This option can be disabled if it breaks things.
Added support for relative paths in the SSH backend.
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.
Adds support for user-configurable read and write buffer sizes while enforcing protocol-negotiated maximums. When not specified, operations default to using the maximum sizes negotiated during the SMB session setup.
Tests revealed that by not using a single connection throttling issues appeared when connecting to Windows shares (possibly due to multiple authentications in a short period of time)
The 'no-reuse-connection' option controls whether SMB/CIFS connections are reused:
When enabled, creates a new connection and authentication for each file operation
When not specified, defaults to reusing the same connection across operations
* Primary functionality implemented for CIFS
This will add CIFS support to Duplicati.
One of the advantages is that the resource does not need to be mounted as the backend connects and authenticates directly to the resource via TCP/or Netbios over TCP.
The authentication supported is domain/username/password. At present integrated Windows authentication is not supported.
This implementation relies on SMBLibrary library (https://github.com/TalAloni/SMBLibrary).
* Fixes to XML documentation
* Implementing single CIFS connection + Fix on PutAsync
Single CIFS connection to avoid re-authentication on every operation.
Fix to PutAsync which only because apparent after file sizes were larger than _smb2Client.MaxWriteSize
* Adding CI tests for CIFS
The CI test for CIFS is self contained, requiring no environment variables. Also updated README.
