Server Recovery

As awareness of the potential business disruption that would follow an IT-related disaster, the disaster recovery industry developed to provide backup computer centers, with Sun Information Systems (which later became Sungard Availability Services) becoming the first major US commercial hot site vendor, established in 1978 in Philadelphia. During the 1980s and 90s, customer awareness and industry both grew rapidly, driven by the advent of open systems and real-time processing which increased the dependence of organizations on their IT systems. Regulations mandating business continuity and disaster recovery plans for organizations in various sectors of the economy, imposed by the authorities and by business partners, increased the demand and led to the availability of commercial disaster recovery services, including mobile data centers delivered to a suitable recovery location by truck.

Disasters can be classified into two broad categories. The first is natural disasters such as floods, hurricanes, tornadoes or earthquakes. While preventing a natural disaster is impossible, risk management measures such as avoiding disaster-prone situations and good planning can help. The second category is man-made disasters, such as hazardous material spills, infrastructure failure, bio-terrorism, and disastrous IT bugs or failed change implementations. In these instances, surveillance, testing and mitigation planning are invaluable.

Organizations cannot always avoid disasters, but with careful planning the effects of a disaster can be minimized. The objective of a disaster recovery plan is to minimize downtime and data loss. The primary objective is to protect the organization in the event that all or part of its operations and/or computer services are rendered unusable. The plan minimizes the disruption of operations and ensures that some level of organizational stability and an orderly recovery after a disaster will prevail. Minimizing downtime and data loss is measured in terms of two concepts: the recovery time objective and the recovery point objective (RPO).

The Institute states that the first three plans (Business Resumption, Occupant Emergency, and Continuity of Operations Plans) do not deal with the IT infrastructure. They further state that the Incident Management Plan (IMP) does deal with the IT infrastructure, but since it establishes structure and procedures to address cyber attacks against an organization’s IT systems, it generally does not represent an agent for activating the Disaster Recovery Plan, leaving The Disaster Recovery Plan as the only BCP component of interest to IT.

Some of the prominent data loss situations in a Server

  1. RAID Controller failure.
  2. RAID rebuild failure.
  3. Failure of intermittent drive resulting in configuration corruption.
  4. Simultaneous failure of multiple drives.
  5. Accidental reconfiguration of RAID drives.
  6. File system/operating system corruption.
  7. Accidental deletion of data while taking back-up.
  8. Natural disasters like flood, fire and earthquake.

The recovery time objective is the time within which a business process must be restored, after a major incident (MI) has occurred, in order to avoid unacceptable consequences associated with a break in business continuity. The recovery point objective (RPO) is the age of files that must be recovered from backup storage for normal operations to resume if a computer, system, or network goes down as a result of a MI. The RPO is expressed backwards in time (that is, into the past) starting from the instant at which the MI occurs, and can be specified in seconds, minutes, hours, or days.

Consultation:

Telephone or Online Consultation regarding what steps ( Precautions & Procedures) to take as soon as Data Crisis Happen. Either the drive can be delivered to our office location in bangalore or it can be picked-up from clients location (Currently available service in bangalore) other city is supported via courier facility.

Diagnosis:

Data Recovery Advisor is an Oracle Database tool that automatically diagnoses data failures, determines and presents appropriate repair options, and executes repairs at the user's request. In this context, a data failure is a corruption or loss of persistent data on disk. By providing a centralized tool for automated data repair, Data Recovery Advisor improves the manageability and reliability of an Oracle database and thus helps reduce the data-recovery

Data Recovery:

In computing, data recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way.
