I made a Time Machine backup to an external drive. When I select the ".backupdb" folder on that drive in Finder and copy it to another location, the destination is much smaller than the source. Get Info in Finder tells me the source is 374GB, and the destination is 61GB.
Is that just a strange effect of Time Machine's multiple versioned copies, or is Finder actually only copying a portion of my files? The Finder copy operation completes without any errors or user intervention.
