Linux and Unix Servers

File Servers, Web Servers, Application Servers, Mail Servers, NAS devices 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.

We perform full data recovery services on NetWare, Apple, Solaris, HPUX, AIX, and Linux servers . Sherlock Data Recovery Services experts are intimately familiar with server hardware from IBM, Hewlett-Packard, Sun hardware as well as numerous others.

Examples of Data Loss Situations - UNIX / Linux

The increased complexity of many server operating systems results in additional data loss
scenarios such as :

• Server registry configuration lost
• Intermittent drive failure resulting in configuration corruption
• Multiple drive failure
• File system corruption
• Accidental replacement of media components
• Flaky Disk Controller card responsible for corrupt data on Mirrored drives

Our Recovery Process

Sherlock Data Recovery Services experts treat Server and RAID loss situations as high priority cases. The initial diagnosis determines whether each media device is accessible to our equipment. If so, we create a raw image of all data from accessible media onto our in house media so that logical analysis can determine the nature of the data loss situation.

If some of the media is inaccessible we 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, drive motors and magnets.

Logical recovery uses the raw images of all the server's media by examining the low-level data tracks and sectors. Our experts 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 obtain access to the important data.

Multiple-drive servers are typically 'destriped' onto our in house 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 parts of the destriped image.

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

Recovery Pricing

Sherlock Data Recovery Services's have recovered from many 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 $100.

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 quote for the recovery of your data.

Recovery Turn-Around Time

Sherlock Data Recovery Services has designed its entire service to recover your data as fast as possible. When dealing with such a wide variety of problems, estimating time periods before the problem is diagnosed is difficult which is why, each recovery case starts with an evaluation.

The evaluation is started immediately upon receipt of your media and generally takes 2 to 48 hours to complete. The process involves several hours of technical 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 EST Monday to Saturday (All Facilities)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 the procedures used and the expertise required to recover your data you require. You are not charged by the hour. A firm quote is provided for your approval following our evaluation.

Critical Response Options

If you have a critical situation and need immediate help, Call us at (212) 249-9888. The Critical Response Service is available 24 hours a day, 7 days a week. Fees for this service start at $100.

Critical Response Service at our facilities

This service is for mission critical data recovery, where the media can be taken to one of our facilities. In the facility, dedicated resources and critical response team members are committed to around the clock to your recovery case until its resolution.

Onsite Service Q

This service is available for situations where immediate shipping to one of our facilities is not feasible or desirable. A technical expert or team of engineers can be dispatched to stabilize and analyze the circumstances of your failure. Response is as fast as possible. For example the time it takes to catch the next plane to your location. This service is not for everybody but if you have a situation that merits this level of service, Sherlock Data Recovery Services is ready to do what is necessary to get the job done.

Our Critical Response Team is comprised of best data recovery experts. They are called on for every kind of situation imaginable from multiple drive multi-Gigabyte and Terabyte RAID servers , Jukeboxes, custom installations and configurations, SQL Database corruption, to tape failure and custom file extraction from corrupted backup sets. Whatever the situation, these technology gurus are ready to recovery your data.

Preserving your Warranty

Sherlock Data Recovery Services has established agreements with most manufacturers regarding preserving warranty during data recovery service. Please Inquire about any given maufacturer.

If the seals on a media must be broken in order to extract data, Sherlock Data Recovery Services will re-seal the media upon completion of service with a tamper resistant sticker which the manufacturer will accept for warranty purposes. You will also receive an invoice receipt to indicate you have pursued data recovery services with Sherlock Data Recovery Services.

When in doubt, enquire with the manufacturer about keeping your warranty while pursuing data recovery.
