This PR changes the restore message when no files are restored.
The logic now keeps track of existing files that do not need to be restored, as well as the actual number of bytes written.
The size of restored files was tracked previously, but was instead reporting the size of the written data.
With this update the legacy restore and new restore report the same numbers.
The warning that is shown if no files are restored has been updated to check if existing files were present, and if so, the restore is assumed to have worked as expected, and an information message is logged, instead of the warning message.
