This PR adds detection of the MacOS Photos folder, and intercepts reads and replaces them with PhotoKit calls.
With this, it is possible to make backups of all MacOS Photos, even if they are not stored locally.
The previous versions would just make a backup of the on-disk structure, which was not guaranteed to contain all photos, but instead has various indexing for finding photos, and may contain some original photos.
The option `--photos-handling` controls how Duplicati now deals with the Photos folder. The options are:
- `LibraryOnly`: Same as before, just treat it as a folder
- `PhotosOnly`: Ignore the folder contents and just back up the actual photos
- `PhotosAndLibrary` (default): Make a backup of the photos and the library on-disk. This may cause images to be stored twice, but de-duplication will usually limit the storage increase.
The option `--photos-library-path` can be used to point to the on-disk Photo library that should be handled, in case the auto-detection does not pick it up. If this does not point to a valid Photoslibrary, or the path is not being backed up, no special handling will be done.
Note that the restore is not restoring into Photos itself, but instead restores into a sub-folder in the Photolibrary that is called `dup_backup`. To get the photos out after a restore, one needs to right-click the Photolibrary folder, and choose "Show package contents" and then the `dup_backup` folder is revealed.
This is done to keep all photos in the same folder, but avoid messing with the structure of the on-disk Photolibrary.
A future update could allow restoring back into Photos, and metadata is captured for each image to eventually allow this.
This fixes#6381
This PR adds a dynamic property so a backend can signal if it supports streaming, based on the settings.
This is currently used for the File backend, so that toggling `--use-move-for-put` will disable streaming on the backend instead of relying on the `--disable-streaming-transfers` flag.
This enables a fail-early approach, where the remote source loads the initial results.
By storing the `IAsyncEnumerable` it is possible to not perform any additional remote calls, even with the initial probing call.
This makes it possible to detect the absence of sources, so the backup can be aborted if sources are missing.
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.
With this interface it is possible to wrap the current support for snapshots and USN and simplify the enumeration.
This makes a number of assumptions into fields such as `IsMetaEntry` and `IsRootEntry` that removes code that was checking for various properties.
This first commit has support for VSS and USN as well as "naked" files, keeping feature parity.
There is also an experimental support for loading a backend-as-a-source. The support for this is currently limited as the backends need to be extended to support a folder concept.
