Will backing up files also include files that are marked for deletion? If i use Time Machine to back up my data to an additional disk, will the backup also contain files marked for deletion that have not been overwritten yet?

To clarify, I do not mean files in the recycling bin, I mean files that have been already emptied from the bin that require tools like Photorec to recover

Thanks for any help
No. Time Machine only backs up files present on the filesystem and furthermore, only those not excluded by a rule or explicit exception. 


On OS X, what files are excluded by rule from a Time Machine backup?
What does Time Machine back up?
