+* `IBackupWriter`: contract every backup writer has to implement. Used to start a backup with or without cancellation and progress reporting.
+* `BackupArguments`: used to create a `BackupWriterFactory`. Contains input and output information.
+* `BackupMetadataInfo`: can be created with `BackupArguments`. Contains information about file size and count which is handled.
