Manufacturer description

The Seagate Backup Plus Portable 4TB external hard drive gives you room for roughly a decade of photo libraries, project files, and system backups in a bus-powered enclosure you can drop in a laptop bag. It connects over USB 3.0 with the included cable, so there is no power brick to carry, and it works with both Windows PCs and Macs out of the box, though reformatting is required if you want to use it with Time Machine. The Seagate backup software handles the routine part: click once for an immediate backup, or schedule automatic hourly, daily, weekly, or monthly runs so your files copy…

Frequently Asked Questions

Does the Seagate Backup Plus Portable 4TB work with a Mac?

Yes. It ships ready for Mac and Windows over USB 3.0, but Seagate notes that reformatting may be required if you want to use it with Time Machine.

Do I need to plug it into a wall outlet?

No. The drive draws power over the included USB 3.0 cable, so a single cable to your laptop or PC handles both power and data.

What warranty comes with this drive?

Seagate includes a two-year limited warranty plus two years of Rescue Data Recovery Services. Check the product listing for current terms in your region.

Can I schedule backups automatically instead of running them manually?

Yes. You can back up with a single click, or schedule automatic hourly, daily, weekly, or monthly backups so copies run unattended.

Do I really get all 4TB of storage?

Not quite. Seagate states that available storage capacity may vary, so formatted usable space lands somewhat below the advertised 4TB.
