[QUOTE="bobtomay, post: 1641524, member: 24160"] Copying files to an external drive and then deleting them from your internal drive is NOT "backing up" those files. You are essentially "moving" those files to a new location. As soon as you delete the files from your internal drive, the external drive is no longer a "backup" drive, it is has become a "data storage" drive. If that data only exists on that single external drive, you do NOT have a backup. If you "completely" erase the internal drive, how are you going to start up the computer? Since "everything" including the operating system will be gone... What Mac do you have? What size drive is in it? include amount of used and free space. What version of OS X are you using? What type of files are you wanting to move from the internal drive and store on an external? Apps, games, movies, music,, etc.? To use an external drive as data storage, you will need another external drive to backup both your computer and the external data. [/QUOTE]
