Does Time Machine do file level backup and restores? If I were to backup my Mac with Time Machine does it do a file level backup or a block level backup? I don't want want some deleted files on my Mac to be stored on my backup HDD and even for restores. For example if I put back the data on the HDD to my Mac does it do a file level or block level restore?
Time Machine works with individual files and folders. You can set up Time Machine exclusions in System Preferences → Time Machine → Options. Any files or folders in this list won't be backed up and won't be restored.
