How to use Time Machine with an external hard drive, such as Seagate® Backup Plus Slim Portable Drive, to easily back up your data, photos, and documents.
Use Time Machine with an external drive, such as Seagate® Backup Plus Slim Portable Drive, to easily back up your data, photos, and documents. Time Machine can automatically back up everything on your computer in just a few steps.
Follow these steps to use your Backup Plus with Time Machine:
1. Plug in your Backup Plus to your system.
2. Open Time Machine from your Menu Bar (or from System Preferences).
3. Choose Select Backup Disk.
4. Select Seagate Backup Plus Drive (or the external drive as shown) connected to your Mac, and choose Use for Backup.
Your external backup drive is now ready, and a Time Machine backup will start within 2 minutes. It’s that easy. If Time Machine has been previously set up, open Time Machine and choose Select Disk then select the external drive.
Note that your first backup may take several hours depending on how many files you have. However, you can still use your computer while the backup is in progress. Thereafter, future backups will complete faster as Time Machine only backs up the files that have changed since the previous backup.
