How to delete back up data from Time Machine backups?

Time Machine keeps the most recent state of your data or recent change in data on your disk. Time Machine creates incremental backups of files that can be restored at a later date. It allows the user to restore the whole Mac data or specific files from the Recovery HD. It works within iWork, iLife, and several other compatible programs. Time Machine allows the user to back up Apple Macintosh computers through Apple's AirPort utility and keep them into network attached storage devices or servers, depending on the version of Time Machine.

Time Capsule?

The wireless network device which is used to keep Mac backup is called Time Capsule. Time Machine doesn't back up every file on your Mac. Some system files are ignored, and you can manually keep backup of such files.
