Back in a Flash is not a flash drive but a USB stick which automatically backs up your files every day and can resuscitate your computer if it crashes.
There is essentially no installation – you plug it into a USB port and click once. Your backed-up files are stored inside the unit daily, without you lifting a finger.
Back in a Flash is compatible with Windows, Vista, XP and 2000. It is available in four storage sizes, from 3.5 GB (under $50) to 31.5 GB (under $200).
