A "Reserve Backup" refers to a secondary copy of data or information that is stored separately from the primary source. This backup is crucial for protecting against data loss due to hardware failures, accidental deletions, or cyberattacks. By having a reserve backup, individuals and organizations can ensure that they can recover important files and maintain continuity in their operations. Typically, reserve backups can be stored on various media, such as external hard drives, cloud storage services like Google Drive or Dropbox, or even physical tapes. Regularly updating these backups is essential to ensure that the most recent data is preserved, minimizing the risk of losing valuable information.
