Are you trying to replace just some files or re-install OS X from a backup? If you open /Applications/Utilities/Migration Assistant and there should be a restore from Time Machine backup.
yes i know regarding this TM restore but it concerns only the final backup right?
i want to be able to restore files from EVERY older backup/day, is that possible to be done auto, or only manually?
Don't know because i never tried. I did reinstall once using an OS X disk and during the initial install it ask if I wanted to reinstall from my last Time Machine backup, and worked out great that way.
However getting all the backup files i never heard of anyone trying that before. What do you want every file in a long backup? It just makes me wonder.
