LINUX -UNIX Data Recovery:

Another reason why UniRecovery continues to achieve such an impeccable success rate is its team of Exchange server specialists. This team of experts have acquired extensive knowledge of recovering data from terabyte servers, like those used by large financial institutions, for example the City Group. UniRecovery has also developed, in collaboration with Pulse Technologies, a very unique and high-tech recovery tool for exchange servers.

Fileservers, Application Servers, Mail Servers, Web Servers, NAS devices (Quantum SNAP, Dell Power Vault etc..) and just plain Servers form the backbone of many corporations' business records storage. There may be one hard drive or many, configured together in volumes spanning drives or striped across drives, on permanent hard drives or removable media.

Windows NT and Windows 2000 are the most popular Operating Systems for servers today but we see many NetWare, Apple, Solaris, HPUX, and linux servers as well. UniRecovery Data Recovery Labs technicians are intimately familiar with server hardware from IBM, Compaq, Hewlett-Packard, Sun hardware as well as numerous others.

1. Examples of Data Loss Situations - UNIX / Linux

Naturally, the individual media in Servers suffer from the same failure points as do drives in personal computers and workstations.

The increased complexity of many server operating systems results in additional loss situations:

  • Server registry configuration lost
  • Intermittent drive failure resulting in configuration corruption
  • Multiple drive failure
  • Accidental replacement of media components

2. The Recovery Process

UniRecovery Data Recovery Labs technicians treat Server and RAID loss situations as high priority cases. An initial diagnosis determines whether each media device is accessible to our lab equipment. If so, the first priority is to create a raw image of all data from accessible media onto UniRecovery media so that logical analysis can determine the nature of the data loss situation.

If some of the media is inaccessible our lab will test the components and closely examine its internal health to determine the extent of physical damage.

Recovery of crashed hard disks often involves replacing failed or damaged components in a clean environment and using specialized hardware and software tools to create the raw image. Failed components typically include electronics, read/write heads, head assemblies, magnets & drive motors.

Logical recovery uses the raw images of all the server's media by examining the low-level data sectors. Technicians must determine both the exact layout of volumes which span or are striped across multiple drives and what fixes to filesystem structures are needed to get access to the important data.

Multiple-drive servers are typically 'destriped' onto UniRecovery media so that filesystem repairs can be performed and the data files extracted. Sometimes the existing filesystem structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the destriped image.

UniRecovery Data Recovery Labs programmers have created a full set of software tools used by our technicians to analyze, destripe, fix & recover data from raw image drives from all operating systems. Once a recovery has been successfully performed, file lists are created and data validity is checked.


3. Recovery Pricing for UNIX / Linux Servers

UniRecovery's Labs have recovered from thousands of these devices over the years. As you may expect, no two data recovery scenarios are identical in all respects. Therefore, this uniqueness makes it impossible to give a realistic indication of pricing without knowing all the facts for a particular case. Generally speaking, pricing starts at about £1000.00 and goes up from this point.

Over the phone, our highly trained Customer Service Consultants will be able to give you some idea of what pricing you would be looking at given your particular configuration and set of circumstances. Sending in your media for a no obligation evaluation will give us all of the information we would require to give you a firm quotation for the recovery of your data.


4. Turn-Around Time

UniRecovery has geared its entire service to recover your data as fast as possible. When dealing with such a wide variety of problems, estimating time before the problem is diagnosed is difficult. That is why, each recovery case starts with a free evaluation.

The free evaluation is started immediately on receipt of the media and generally takes 2 to 48 hours to complete. The process involves several hours of work and testing.

Complete recovery turn-around time including analysis and recovery is usually between 1 and 5 days. Some severe cases can take considerably more time.

Our hours of operation are 9am to 7pm Monday to Friday (All Labs), 9am to 5pm Saturday. If you have an emergency situation, we have technical staff on call for weekends and after hours in all locations.

Time estimates are based on procedures and expertise required to recover the data you require. You are not charged by the hour. A firm quote is provided for your approval following the evaluation.

All About Recovery Planning: Why Plan?
The primary objective of a Business Continuity or Disaster Recovery Plan is to enable an organization to survive a disaster and to re-establish normal business operations.


In order to survive, the organization must assure that critical operations can resume normal processing within a reasonable time frame. Therefore, the goals of the Business Continuity Disaster Recovery Plan should be to:  
  • Identify weaknesses and implement a disaster prevention program
  • Minimize the duration of a serious disruption to business operations
  • Facilitate effective coordination of recovery tasks
  • Reduce the complexity of the recovery effort.

Historically, the data processing function alone has been assigned the responsibility for providing continuity planning through a Disaster Recovery Plan, typically associated only with recovery of IT functionality. Frequently, this has led to the development of recovery plans to restore computer resources in a manner that is not fully responsive to the needs of the business supported by those resources.

Business continuity planning is more comprehensive with a business operations focus rather than a data processing focus. In the past year, it has become clear that disaster recovery must include a business process oriented business impact analysis and a determination of what other systems are required to operate, such as: paper forms, skilled and knowledgeable people, special equipment, communications systems, work space and inventory.

In today's environment, the effects of long-term operations outage may have a catastrophic impact. The development of a viable recovery strategy must, therefore, be a product not only of the provider's of the organization's data processing, communications and operations centre services, but also the users of those services and management personnel who have responsibility for the protection of the organization's assets.

The methodology used to develop the plans, emphasize the following key points:  
  • Providing management with a comprehensive understanding of the total effort required to develop and maintain an effective recovery plan
  • Obtaining commitment from appropriate management to support and participate in the effort
  • Defining recovery requirements from the perspective of business functions
  • Documenting the impact of an extended loss to operations and key business functions
  • Focusing appropriately on disaster prevention and impact minimization, as well as orderly recovery
  • Selecting project teams that ensure the proper balance required for plan development
  • Developing a continuity plan that is understandable, easy to use and easy to maintain; and
  • Defining how continuity planning considerations must be integrated into ongoing business planning and system development processes in order for the plan to remain viable over time.

The successful and cost effective completion of such a project requires the close cooperation of management from all areas of Information Systems as well as business areas supported by Information Systems. Senior personnel from Information Systems and user areas must be significantly involved throughout the project for the planning process to be successful.

What if I Don’t Plan?  
  • Loss of business if a disaster occurs - A recent group study found that:
    • 70% of companies that suffer a major IT disaster, without a valid recovery plan in place, fail within the next year.
    • Of those that do survive, only 10% make a full recovery.
  • With out a plan, recovery is guaranteed to be slower, resulting in:
    • Loss of customers
    • Lost sales revenue
    • Loss of shareholder confidence
  • Without a plan, recovery is always more expensive
  • Investors will require it
  • Protection of directors from liability concerns
  • SEC requires it for public companies
  • Numerous regulations require planning (see the Knowledge Base at www.DisasterRecovery.com)
  • NFPA standard 1600 may soon be law, which will require a written plan for all companies and buildings (similar to Y2K plan requirements for all business to have a written plan)

What do You Mean by a Disaster?

This is a typical question, based on the thought “What kind of disaster would I possibly need to plan for?” A disaster is defined as any event, which disrupts operations to the point of having a significant interruption of service or operation with a resulting negative impact, such as:

  • Storm
  • Fire
  • Employee Strike
  • Tornado
  • Hurricane
  • Flood
  • Malicious employee damages systems
  • Hardware failure
  • Software failure
  • Virus
  • Theft or robbery
  • Implement a Plan

In closing, it is important to keep in mind that the aim of the planning process is to:

  • Assess existing vulnerabilities
  • Implement disaster avoidance and prevention procedures; and
  • Develop a comprehensive plan that will enable the organization to react appropriately and in a timely manner if disaster strikes.

Plan your response to a disaster. Disasters do not come with advanced warning and thinking it all through in advance and preparing a written procedural response to business resumption and recovery is the only prudent and responsible course of action.

A written, well-prepared Business Continuity and Disaster Recovery plan is an absolute must for business success in our world today.
