[QUOTE="snoslicer8, post: 535176, member: 19029"] Time Machine is a little bit smarter about backing up your internal drive than most people give it credit for. What happens is the FIRST time Time Machine runs, it creates a mirror image of your internal drive. This takes the longest of all the backups. After this backup, Time Machine examines your internal drive every hour that your computer is turned on. It polls the recent changes to your drive. If any files have a NEWER timestamp than the last time Time Machine examined the drive, it stamps that file, and backs it up to the external drive. This is where it gets tricky...Time Machine keeps a log of all the files it backs up, where it stores different versions of files as you change them and it backs them up, and at what time each file was backed up between changes/adding/removing files, etc. In essence, once Time Machine backs up your drive for the FIRST time, your backup external (or internal) drive will fill up MUCH SLOWER than it did with the first backup. Unless you are in the habit of downloading or storing HUGE files on your internal drive, your Time Machine backup drive will fill a lot slower than you think. [/QUOTE]
