BACKUP
 
The "Backup" service or the "Backup" process means making copies of the data so those additional copies can be used to recover information after an unexpected loss. The process is copying and archiving of computer data and the retention of those copies over a time period (for example, several days, weeks or months). The archived date is used to recover information in the event of an unexpected loss due to a hardware malfunction, human error, or negligence. Backup creation is important in computer information services as data loss can lead to significant financial cost because impossibility to recover data (such as content or source code of a website, emails, databases or other client information).
 
DISASTER RECOVERY PLAN (DRP)
 
The DRP is a process which delineates how an organization will respond to any given disaster scenario, with the goal of supporting time-sensitive business processes and functions and maintaining full business continuity.
A DRP contains both responsive and preventative elements. On the responsive side, a DRP delineates numerous disaster scenarios, and defines the detailed responses to each, with the aim of minimizing that event’s negative impact. On the preventative side, a DRP aims to minimize the negative effects of specific scenarios by defining what the organization needs to do in order to avoid them.
More specifically, a DRP needs to anticipate and delineate a plan of action in response to the loss of such mission-critical IT components and services as:
 
• Critical IT hardware including network infrastructure, servers, desktop or laptop computers, wireless devices, and peripherals
• Service provider connectivity
• Enterprise software applications
• Data storage devices or applications
 
To achieve maximum efficacy and keep costs in check, organizations should plan to leverage a combination of internal resources and vendor-supported solutions in their Disaster Recovery planning.
