By changing to IEnumerable, it is possible to iterate only a portion of the list, which is useful when not all entries are needed (e.g., when testing a connection).
All existing backends have been updated, and any which were able to be changed to yield return results in a straightforward way now do.
Many backends had a try/catch in the List() method. Due to the fact that yield returns can't be placed within a try/catch block, these have been refactored to either scope the try/catch to the parts that (should) be the only places throwing exceptions, so that exceptions are still caught and handled.
Note that lazy evaluation may cause some changes in behavior - exceptions that were previously thrown at the point of invokation of List() may now be thrown while it is being enumerated.
I believe this will not be problematic though, as the only well-known exception seems to be FolderMissingException, which should be thrown by Test(), but TestList() attempts to enumerate the list to force this exception.
Any places that require the legacy behavior can get it by simply converting the lazy enumerable to a List()
It also makes quota enabled backends return an instance of this interface instead of the quota components separately.
This way, getting quota stats requires only a single remote request on backends like Google Drive and OneDrive.
It is now permitted to specify the target or source path, without the file:// prefix, but ONLY if there is also a "backup" or "restore" argument, otherwise it is not possible to infer what to do.

Problem was that the backend also supports urls like: file://user:pass@\\server\path.
Now the username and password is only accepted if it does not contain slash or backslash.

Changed the non-streaming file-backend interface to use sytem copy calls rather than
manual stream copy.

Previously some backends autocreated a missing folder, and some threw an exception.
The new standard is that all backends throw the FolderMissingException on all access (except delete).
This means that the Test() and List() methods are now the same for all stock backends.
Third-party applications that use the backends should implement custom logic to auto-create the folders,
when the FolderMissingException is encountered.
Duplicati auto-creates missing folders, but this can be toggled through the new flag --disable-autocreate-folders.
In case the auto-create fails to detect a missing folder, there is now a "create-folder" action in the commandline version.
Update issue #102
Status: Fixed
The IBackend_v2 interface has the CreateFolder and Test methods.
The CreateFolder is exposed to the commandline interface with the action create-folder.

This was based on the idea that the interfaces should remain static.
I hope this change is enough to ensure stable interfaces until release 1.2.
Overview of changes:
Moved all interfaces into the same dll.
Encryption and compression is now plugable modules, just as the backends.
Encryption/compression can now register an UI.
Encryption now uses AESCrypt as a default.
GPG does not default to using the --armor option.
Added support for generic modules, but none are written yet.
Added support for plugable settings pages in the "Options" dialog.
Fixed issue #148.
Duplicati now uses AESCrypt as the default encryption format.
Fixed issue #199.
GPG now supports custom commandline options.
Fixed issue #207.
Encryption modules are now plugable.
Fixed issue #118.
S3 credentials are now stored.
Fixed issue #151.
Backends can now register system wide options.
