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 PR updates the file copy to use a temporary stream, instead of a memorystream to preserve memory.
It also fixes two places where rewinds were needed, and replaces the compare of streams with a hash compare.
This PR adds the option to suppress warnings by their log id. Warning IDs that are supplied to `--suppress-warnings` will be converted to information messages before being logged.
If a specific warning is disabled, such as `CompressionReadErrorFallback`, this will then no longer count as a warning for the job, and the log file will see the warning as an information message.
This PR also adds two simpler filter options that makes it possible to filter log messages by supplying the log IDs. This can already be achieved with log filters, but the ID filter is a bit simpler to apply, as you only need to know the ID.
Finally, this PR also adds common logging for errors in the categories:
- Permission denied, id = `PermissionDenied`
- File locked, id = `FileLocked`
- Path not found, id = `PathNotFound`
- Path too long, id = `PathTooLong`
These new log ids makes it simpler to ignore warnings about locked or inaccesible files.
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.
