Using Time Machine for the First Time
...
Before you start using Time Machine, you will want to purchase an external hard drive on which you will be backing up all of your data. The larger the external hard drive, the better. 1 TB hard drives are quite affordable and will provide you with more than enough storage to back up your computer. For support regarding the use of external devices, please see the product documentation or contact the manufacturer.The first time you back up your computer, it can take quite some time, so be sure to give yourself plenty of time before starting your backup.

Time Machine preserves permissions in files. If you didn't have permission to read a file before backup (such as a document from another user account on the local machine), you won't be able to read it after the file has been backed up or once it is restored. |
