I want to backup my main data files to an external hard drive,

Customer Question

I want to backup my main data files to an external hard drive, but I don't want to replace the last backup. I have an iBook, Mac OS X, 10.4.9

GreetingsCustomer are you using a backup program? Are you using any type of file compression utility such as Stuffit? Did you store the original backup on the external drive?
Customer: replied 5 years ago.
I am not using a backup program. I don't know how to use stuffit. I see it in my Applications Folder under Utilities. "Create Archive" seems to be a file compression utility, according to mac help in Finder, but I wasn't able to use it.

Yes, I did store the original backup on the external hard drive. What I want to do is to burn (on an external DVD burner) DVD's of my back ups, because I have had to move iPhoto and iTunes off the laptop and on to the external hard drive. So I will be using the external hard drive for data files for the laptop
Expert:  Dan - Master Tech replied 5 years ago.
You can create an archive backup of a file or folder by holding down the "ctrl" key and clicking on the item in the finder window. This will create a .zip archive and you can then copy it to another location or burn it to a disc. The other option is to hold the "ctrl" key select the Copy option instead. This will create an uncompressed copy of the original folder or file. Drag the copied file/folder to a newly created folder labeled "Backup Files" or some other appropriate name and burn or copy to another drive.
Customer: replied 5 years ago.
I tried again to create an archive using the control key as you suggested, and got the same message as twice before: "A file reference cannot be created" I am trying to back up my home folder, it is 3.74 GB - too large to burn on one DVD.
When I select copy with the control key nothing happens. Where does the new copy show up?

If I use the copy method, where do I create the new folder.
Expert:  Dan - Master Tech replied 5 years ago.
Sorry, I meant to say duplicate. It will create another file/folder of the same name with the word "copy" attached in the same directory.
Perhaps the easiest thing to do is to just create a new folder with the date on the external drive such as Backup 10_05_08 and drag your home folder to it and it will copy it without transferring the contents. Just open two windows and drag and drop.

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
