Luckily, Apple has heard your cries:
iTunes: Back up your iTunes library by copying to an external hard drive:
Consolidate Library
- Open iTunes Preferences:
- Choose iTunes > Preferences.
- Click Advanced.
- Make sure the option to "Copy files to iTunes Media folder when adding to
library" is selected.
- Click OK.
Note: After you click OK, iTunes
copies any files that are added that
weren't already in the iTunes Media
folder and places the copies in the
folder. The original files are left in
their original locations. To save
space on your hard disk, you might
want to delete the original files
after confirming import.
- Choose File > Library > Organize Library.
- Select the option to "Consolidate files."
Note: If you recently updated to
iTunes 9, you might want to consider
selecting the option to "Upgrade to
iTunes Media organization." This
updates the file organization of your
iTunes Media folder.
- Click OK.
Move to External Drive
- Quit iTunes.
- Locate your external hard drive.
- On the desktop or Finder sidebar.
- Locate your iTunes folder:
- By default, the iTunes folder is located in: /Users/username/Music
If the iTunes folder is not in the
default location listed above then you
can find where the iTunes folder is
located by following these
instructions:
- Open your iTunes Preferences:
- Choose iTunes > Preferences.
- Click Advanced. The location of your iTunes folder will be listed in
iTunes Media folder location box.
- Drag the iTunes folder to your external hard drive. This can take a
while if you have a lot of items.
- When the transfer is complete, your iTunes Library will have been
successfully copied to your external
hard drive.
Restoring your iTunes Library
- Quit iTunes.
- Locate your external hard drive.
- On the Desktop or Finder sidebar.
- Drag the iTunes folder (backed up earlier) from your external hard drive
to whatever location you desire on
your internal hard drive. It is
recommended that you choose the
default location for the iTunes
folder, which is:
/Users/username/Music
- Open iTunes while holding down the Option key (Mac) or Shift key
(Windows).
- In the resulting dialog, click the Choose Library button.
