Backup or Restoration?
What's more important - Backing up your data or being able to restore it? Well they are actually equally important, right? Most people would say yes and I would agree. That's what CDP is all about. Continuous Data Protection (CDP) is a storage system in which all data is backed up whenever any change is made. Essentially what happens is when any user changes and saves data each occurrence is captured and stored to a specific and separate storage location.
Traditional backup only allows you to recover data to the point at which backup was taken, which is typically done on or at a specific scheduled time. With CDP there is no need for the nightly "scheduled" backups and you can literally restore data to any point in time.
