Manufacturer description

The Seagate Backup Plus 2TB desktop external hard drive (STCA2000100) is a set-and-forget backup box for people who want their photos, projects, and system images living somewhere other than one laptop. It holds 2TB and connects over USB 3.0, so large transfers finish faster than the USB 2.0 drives it replaced. The Seagate Dashboard software does the actual work: the Protect function sets up a one-click or scheduled local backup plan, while the Save feature pulls user-generated content down from your social networks and the Share feature pushes multiple files back up in one pass.

Frequently Asked Questions

Does this Seagate Backup Plus work with a Mac?

Yes. It ships with a pre-loaded NTFS driver for Mac, so you can use the same drive on PC and Mac interchangeably without reformatting it.

How much space do you actually get on a 2TB drive?

Seagate states that available storage capacity may vary, so plan on somewhat less than the full 2TB once formatting overhead is accounted for.

Can this drive back up automatically instead of by hand?

Yes. The Seagate Dashboard's Protect function lets you set a one-click backup plan or build a custom scheduled local backup.

Does it support Thunderbolt or FireWire 800?

Only with an optional adapter. Out of the box the connection is USB 3.0; Seagate offered separate adapters to upgrade to Thunderbolt or FireWire 800.
