Protecting data while in DR mode

Bookmark This (opens in new window)

While in disaster recovery mode – that is, during a disaster when critical business applications are operating in alternate locations – all of these protections are also needed:

  • DR servers need to be backed up
  • Backup media needs to be protected, usually through off-site storage
  • Transmitted data must be protected
  • Critical data must be stored on resilient storage systems

In disaster mode, business information and processes are just as critical as they are in times of normal operations. Consequently, the systems and processes in use during a disaster must provide the same level of protection as the primary systems and processes.
