backup device
Storage safety net
A backup device is hardware used to copy and store data for safekeeping—typically an external hard drive, USB flash drive, or tape drive.
The term emphasizes the device's purpose rather than its technology: protecting against data loss from hardware failure, theft, or accidents.
I keep a backup device in my desk drawer just in case.
