FAQ
Look for compatibility with your operating system, a connection that matches your computer’s ports, and support for your preferred backup software. Also check whether the drive uses USB power or requires a separate power adapter.
Yes. Compatible backup software can schedule backups to an external hard drive while it is connected. macOS includes Time Machine, while Windows offers File History for personal files. Setup options depend on your operating system and the software you choose.
Yes, but the drive’s file system matters. Windows and macOS both support exFAT for general file storage. Backup applications may require a different format or a dedicated volume, so check their requirements before setting up a drive for use with both systems.
A full backup copies all selected files. An incremental backup copies changes made since the previous backup, while a differential backup copies changes made since the most recent full backup. Your backup software determines which methods are available.
Many external hard drives connect through USB, using a cable with a USB-A or USB-C connector at the computer end. Some drives support Thunderbolt. USB-C describes the connector shape, not the connection standard, so check both the drive’s specifications and your computer’s port support.
