Testing single site with in multisite and full multisite backups, I took snapshots of both.
I then Added an image into a new post.
Ran restore for single site - the images remained in the uploads folder, but were removed from the media library (aka: a database change only)
Ran restore for entire multisite - the images remained in the uploads folder, but were not present in the media library (aka: a database change only)
Ran another full multisite backup, then Deleted the files from the uploads folder, and tried full site restore - the files came back in the uploads folder.
* Files will be backed up if they exist, and will be restored if they have been deleted
* Uploads folder will not have any files removed upon restore, so there are security implications for site rollback, and just general clutter of the uploads folder if it is not cleaned up in some other way.
Question: Is this expected behavior, and if so, can you point me at a good uploads cleaner as this isn't part of snapshot pro?
