Installing BounceBack Essentials is easy, requiring only a few clicks and correctly entering a serial number. Essentials requires a dedicated drive with enough room for all your data to perform its magic. Essentials keeps only the current version of any file in one location–in effect, mirroring your main system, much like a RAID setup. The Ultimate package–which offers additional features such as encryption, multiple destinations, and point-in-time recovery–costs $69. BounceBack Essential is a $29 subset of the company’s BounceBack Ultimate software. Note that the software I tested bore the name BounceBack Essential, but you’ll also see BounceBack CDP or Instant PC Recovery depending on where you look (the company has a penchant for multiple labels). In that regard, CMS’s BounceBack Essential 9.1 calms your soul, and does so flawlessly with as little user intervention as possible. There’s something about maintaining a complete and up-to-date copy of your entire operating system and software installation that brings you peace of mind.
