A drive-based backup takes a snapshot of your entire hard drive, capturing every bit of information that is stored on it for later retrieval. All of your files, folders, desktop settings, programs, and your operating system are captured into a recovery point. You can then use that recovery point to restore individual files or folders or your entire computer.
By default, scheduled independent recovery points or recovery point set names are appended with 001.v2i, 002.v2i, and so forth. Recovery point set names are appended with _i001.iv2i, _i002.iv2i, and so forth. For example, if your base recovery point is called CathyReadF001.v2i, the first incremental recovery point is called CathyReadF001_i001.iv2i.
