Backing up your Mac is simple and important. We recommend it for everyone.
Back up with Time Machine
- It doesn’t matter whether you have a 1TB, 2TB, 3TB, 4TB or 5TB Seagate Expansion. You can have it and use your Seagate Expansion on your MacBook Pro, MacBook Air or iMac.
- Please follow this procedure to set up a backup using Time Machine: If you have not done so already, set up your Seagate Central. Open System Preferences and then select Time Machine. Select the option Select Backup Disk. Select your Seagate Central, which will be TM BACKUP from the list of backup options. (Optional: You may check the Encrypt Backups box.).
Time Machine is the built-in backup feature of your Mac. It’s a complete backup solution, but you can use other backup methods as well.

How much space do I need for a backup?
To see the size of a specific file or folder, click it once and then press Command-I. To see storage information about your Mac, click the Apple menu in the top-left of your screen. Choose About This Mac and click the Storage tab. For Time Machine backups, it's good to use a drive that has at least twice the storage capacity of your Mac.
