==Mitigation==
When an individual needs to deal with a ransomware infection, backups become vital. Since most ransomeware uses encryption, data on targeted devices is often impossible to recover unless the ransomware publisher provides the decryption key. Even with backups, users must be careful during the recovery process.
===Preparation===
Computer users should be sure to regularly back up their personal files on external drives. USB Flash drives, external hard drives, and other such devices can be used for this purpose. In between backups, the drive(s) should always be kept disconnected from that computer, and preferably all others as well.<br />
Ideally, the individual will also create complete system backups periodically. This can be done using software such as DriveImage XML. These disk images should be stored on a separate storage device as well, and only connected to the computer at risk when backups are being created. If possible, it is also wise for the individual to keep older images, in case the more recent images were infected, or are for some reason corrupted.
