Backup drives.

Also written external hard drive, desktop external drive, offsite backup drive, 3-2-1 backup.

Which external drive for backup?

One that is not the computer. A desktop external drive with its own power supply holds the most per rupee; a portable drive runs off the USB port and goes offsite in a bag, which is the copy that survives a fire or a ransomware note. Keep three copies on two kinds of media with one away from the building, and rotate the drive that travels.

Data Systems poster on the anatomy of a ransomware attack, an open bank vault with documents flying out and a padlock, listing initial access, spread, data theft and encryption
Anatomy of a ransomware attack. The four stages of a ransomware attack: initial access through phishing, stolen credentials or vulnerabilities; spread across systems; theft of sensitive files; and encryption that makes systems unusable. Patching, limiting access and testing isolated backups reduce the impact, and data theft can happen before encryption. From the Wall of Networking.
