This occurs if the TargetDirectory or TargetFile parameter contains a file with the same name as a file specified in the SourceFile or SourceDirectory parameter.
In compressed extents, individual blocks are not compressed separately; rather, the compression stream spans the entire extent.
You first need to boot your new computer with the empty disk in order to restore your data onto it. Optionally, if speed is more important than archive size, you can degrade compression specifying the compression level: GUI over libdar are nice to use, to backup once.
Taking snapshots of a subvolume is not a recursive process; thus, if a snapshot of a subvolume is created, every subvolume or snapshot that the subvolume already contains is mapped to an empty directory of the same name inside the snapshot.
