Sounds like problems with the backup, 
not the disk you're restoring to.

Looks like you're doing your fsck while the filesystem is mounted
read-write.  Don't do that.  Unmount it first (single-user mode is
good for this), and *then* fsck it.  You probably won't find any
problems at that time, though -- the unreferenced file handles may
just be normal open handles that will be cleaned up when the
filesystem is umounted and flushed to disk.
