RAID Data Recovery, SAN and NAS Recovery

Need quick and efficient RAID data recovery? Our RAID recovery team are equipped to deal with all types of RAID file recovery and RAID repair.


Servers, whether for file storage, running applications, virtual environments, web servers, or mail servers, form the backbone of many corporations’ IT infrastructure. There may be one hard drive or many, configured together in volumes spanning drives or striped across drives, on permanent disks or removable media.


Data Recovery Server Room

Servers have the same vulnerabilities as personal computers, but the increased complexity of server operating systems, complex multi-topology arrays, VMWare and ESX and Enterprise environments results in additional risk situations.


If you’ve lost critical data on a RAID, SAN or NAS device, don’t panic. Call 0800 LOST FILES (0800 5678 34) for immediate help. Data recovery is our specialty, so whatever the circumstances, there’s a very good chance that we can recover the missing data quickly and efficiently.


Common issues with server systems include:

  • RAID controller failure
  • Accidental reconfiguration of RAID drives
  • Accidental replacement of media components
  • Lost server registry configuration
  • Single/multiple drive failure
  • Partition(s) or MBRs have been damaged or deleted

Server types

We have experience recovering data from all types of server storage and operating systems, and are very familiar with hardware from IBM, Sun, HP, Compaq, Dell, and common server operating systems such as Windows, Linux, Unix, Mac, Solaris, Netware, VMware and more.

Complex Multi-Topology Arrays

Cutting edge technology comes at a price. It also comes with a very steep learning curve in the form of administration, configuration and operating knowledge. One wrong move, or concurrent failure, can bring down an essential piece of storage technology and with it, an enterprise’s most critical data.

Over 16 years we have developed many proprietary procedures to meet the most demanding situations.

Virtualisation: VMWare & ESX

Instead of multiple hardware assets each controlling one or two individual core IT functions, virtual machines provide all of these roles within a single high-end server. With the added complexity of a virtualised environment, the array may contain operational instances of many different varieties of operating systems and server iterations. Consequently, the data content can be virtually impossible to retrieve without a thorough understanding of the vast number of combinations and attributes of this type of storage facility.

After building a construct of the array using hexadecimal analysis and RAID controller emulation, our engineers work backwards from the file level, creating a comprehensive map of the logical topography as they work through the various environment layers. Once they have reached the root level, or “hypervisor”, they scan for the signatures of the virtual machines and subsequently recover them.

Enterprise Storage: SAN & NAS, iSCSI, Fibre Channel (FC), Fibre Channel Over Ethernet (FCoE) & InfiniBand (IB)

Serving a massive amount of data calls for extremely high throughput and a solid piece of equipment to handle the user load. Enterprise filers are designed for this one purpose and perform this task exceptionally. However, even the most carefully designed fault-tolerant servers can fail, causing at the very least massive inconvenience to the enterprise.

Usually designed around a solid RAID level such as RAID-6 (dual parity), the manufacturer often goes one step further and improves on these elements, creating a unique proprietary solution which is supported only by the manufacturer’s equipment.


Data Recovery - RAID Server

This is compounded by the enormous volume of disks in these arrays, typically 20 – 60, creating an exponentially greater challenge in recovering data from these monolithic arrays.


Our engineers must identify the exact parameters of the array, through hexadecimal and Boolean algebraic analysis, in order to interlace the clones of all constituent disks and comprise a single entity. In addition to this, the unique properties of these enterprise storage devices necessitate creation of a custom solution to interface with, and extract data from, the established construct.


We regularly use these custom solutions to successfully recover from huge arrays – recently 2 appliances each containing 3 32 disk volumes.

Pricing and turnaround

Due to the importance of servers to most businesses, we treat RAID and server loss situations as high priority. As there are so many different factors involved in recovering data, you will need to call a consultant on 0800 LOST FILES (0800 5678 34) to assess the specifics your situation.


Data recovery is our specialty, so whatever the circumstances, there’s a very good chance that we can recover the missing data quickly and efficiently. Complete recovery turn-around time including analysis and recovery is usually between 3 and 5 days. Some severe cases can take more time.
