Well, I do know that TimeMachine uses hard links to reference files and folders that have not changed since the previous backup. That saves a tremendous amount of space on the backup disk.
Are patent cases more “favorable” to patent claimees in the Tyler area because of stupid jury members?
Where is the lawsuit against any computer company for someone claiming to have patented the use of a keyboard to input data into a computer or other electronic device?
Our patent system is as out-of-wack as our current administration...
You’re pretty close. It just backs up everything every hour, meaning hard links for everything, but only copies the data (and points the hard link to it) if the file has changed or is new. Otherwise, the hard link points to the last previous backup. That’s how it looks like you’re looking at your whole file system. As you know, Spotlight keeps track of all your files for searching, but Time Machine also leverages Spotlight to find out which files have changed or been added. Ars Technica had a very in-depth article on this a while back. I can dig it up if you want.
