Once you have stored your files on another drive or a storage server, you can often simply connect to that source and drag the files back to your computer’s hard drive. If you used special software provided by your external hard drive or CD/DVD Recorder, you may have to use that same software to browse the backup set and select which files you wish to restore. If you’re using an online storage service that syncs files between your computer and its server, you files should be kept up-to-date automatically. If you ever need to replace a hard drive or switch computers, simply reinstall the service’s software and select which folders you want to sync with your computer.
