Back up to an external drive.
You can back up to CDs or DVDs, but this is a slow, manual process. And contrary to popular belief, most CDs and DVDs are not permanent. Low-priced CDRs may not be readable in as few as two years and thumb drives are small, lower capacities, and easy to lose.
The best backup medium is an external hard drive. It takes stacks of CDs or DVDs and handfuls of thumb drives to back up all the data that could be stored on a single external hard drive. WD SmartWare Pro makes it easy to back up to an external hard drive. High-capacity external drives are fast and allow you to keep all your backed up data in one place. For extra safety, get a two-drive external storage system and dedicate half the capacity for mirroring to automatically and instantaneously back up your backup every time. WD's external hard drives are sleek, stylish, made for your grab-and-go lifestyle and most come with our easy-to-use backup software... so let WD be your backup plan!
