Data Recovery - a Brief Introduction

Data Recovery – A Brief Introduction

Data Recovery is the process of retrieval of inaccessible or corrupt data from digital media that has become damaged in some way. Data Recovery can be used to recover data from devices as varied as Hard Disk Drives, Memory Cards, Tapes, Mobile Phones, Personal Digital Assistants, Floppy Disk’s, CD’s, DVD’s, Data Cartridges, Xbox’s and many more items.

Data Recovery may be needed for reasons as diverse as hardware failure, (the tape has been ‘chewed’ up, the hard disk drive has failed, the user has maliciously damaged the computer or digital device, or it could have suffered fire or flood damage). All of these instances will require the services of a professional data recovery company if the data was of such value (be it sentimental or financial) that the cost of the services are less than the perceived value of the data which is no longer accessible.

It is not just businesses who are at risk from Data loss. Clients requiring data recovery come from all walks of life, including large corporates, smaller businesses, and the self employed to “joe public” who, with the introduction and subsequent boom in the use of digital cameras etc to record holidays and special occasions may have lost anything from sentimental data to critical e-mails, and personal account details. Students are often grouped under this heading too.

There are numerous ways that Data can be recovered from digital media which can vary greatly, the simplest method can often involve the running of basic software on the storage medium in question. This is always a dangerous idea, because the recovery data could overwrite the very data that is being recovered. More complex commercial software tools are available which will do this job more professionally. No software fix should be attempted prior to the original media being imaged, enabling the recovering company to work on a ‘back-up’ of the original software. The most professional companies will also take a second image should there be a problem with the first image that is being worked on for recovery.

The next problem is what happens when the hard disk or storage device doesn’t work. For the smaller ‘Data Recovery Companies’, this is a problem, and it is when the more serious Data Recovery Companies get involved, (such as Disklabs, http://www.disklabs.com ), who specialise in higher end Data Retrievals. It is always recommended that the most critical work should be sent to a true data recovery specialist, (check out the accreditations - ensure the specialist has ISO9001-2000 Quality Assurance status, and is certified to ISO BE EN 14644 to ensure that their clean facility is at the correct level for intrusive data recovery work, find out how long that company has been trading, and check their testimonials). Once you have found the company that you are happy with, if the data storage device doesn’t work, there is a high likelihood that the digital media will require spare parts, this is where organisations such as 1st Computer Traders Ltd, ( http://www.1ct.com ) are of service. Organisations such as 1CT sell spare parts for hard disk drives to organisations such as Disklabs, ( http://www.disklabs.com ) enabling them to get the original data accessible for long enough to image the data onto a stable storage device, enabling that data to be duplicated again which in turn allows a safe recovery attempt to be achieved.

The data recovery job is generally finished when a list of all the recovered files is sent to the client. Once the client approves this file listing, they are then shipped the data of an appropriate media. This can be a hard disk drive, floppy disk, CD or DVD. Alternatively, if a file is considered critical, it can be encrypted and then emailed to the client.

It should be noted that in extreme cases it may be impossible to recover any data, however the bottom line is, as soon as you have lost data you should power off your device and send it to a professional Data Recovery Company to optimise your chances of a successful recovery.

Data Retrieval Software

7 Tiers of Data Recovery - Software Aspects

tive summary

Disaster recovery planning is one of the key components of smooth business security strategy. While hardware component of such planning is well discussed in the manuals and white papers of hardware providers, the software component, being no less important, is often overlooked in the planning.

Solid File System (SolFS) is a software component for programmers working on data storage and data integrity solutions. Integration of SolFS into data recovery solutions will reduce recovery time, minimize data loss and insure data integrity, prevent malicious tempering or destruction, and reduce requirement for highly-skilled IT workforce. This white paper analyzes advantages of SolFS use in the area of data recovery following a disastrous event of any nature.



Recovery Planning

Statistics show (Jim Hoffer, Health Management Technology) that only 6% percent of enterprises fully recover after serious software or hardware disaster, either malicious or due to negligence, while 43% never reopen and the remainder 51% of companies close within two years.

Planning for data recovery became an ubiquitous and necessary process for any company that can not afford significant downtimes due to data loss, and in real life this means every company. The inevitable losses resulted from company activity interruptions can come from:



Direct revenue loss

Loss of “face” — customer trust, damage to company image, etc.

Brand damage

Loss of know-hows, insiders information leaks, public availability of privileged data, etc.

Legal costs



The key elements needed to prevent these severe consequences of a disaster and to insure business continuity is careful proactive planning of disaster recovery strategy. For every business process such strategy must define a Recovery Point Objective (RPO) and Recovery Time Objective (RTO). As always, a right trade off between costs and speed/effectivenes of recovery should be chosen. Obviously, the zero data loss, zero recovery time solutions are the most expensive.

Besides well-known hardware based precautions, one of the way to reduce costs of disaster recovery is use of custom file systems, such as Solid File System. Solid File Systems allows creation of huge encrypted compressed single file storages encompassing any type of data. This paper analyzes possible application of Solid File System (SolFS) on every of seven traditionally identified tiers of business continuity solutions.



Tier 1: Data backup with no hot site

Businesses with Tier 1 continuity solution rely on tape backups made at specific time intervals. These tapes are then shipped off site for storage. For the reserve copying purposes, it is very convenient to place data into a SolFS-based storage. All documents will be conveniently stored in one file. There is no need to rewind the tape searching for a specific document - the whole storage can be quickly restored. Moreover, the fact that SolFS has built-in cryptographic protection, allows the company to entrust tape storage to almost any third-party service provider without risk of information leaks. In this case the keys or passwords used for encryption should be safeguarded and kept separately from backups. A loss of such key will not effect feasibility of storage restoration, but will make access do stored data impossible. SolFS also allows use of incremental backup systems working on the sector-by-sector basis: there is no need to update the whole storage file when minimal changes have been made to the data. Practicability of this approach depends on the frequency of stored file changes, i.e. on the specific application. The advantage of reserve copying whole storages is that the backup system does not need to know the internal structure, encapsulation level, or directory tree of the storage. The whole storage will be copied without possibility of loss of a single file attribute. In addition, SolFS supports native data compression. If a SolFS storage contains data susceptible to compression, use of SolFS for whole storage compression is much more time- and cost-effective than use of regular compression tools applied to separate files or folders. SolFS-based storages use journaling for self-integrity checks. If a part of a tape or sector on disk becomes physically damaged and unreadable, the whole storage, save the damaged file(s), remains intact and functional. There is also a possibility to backup separate files from your SolFS storage, if necessary. SolFS Driver Edition allows making access to your storage as regular files and folders from the application of reserve copying or any other application. This also makes possible development of a monitoring tools watching the changes made to files inside a SolFS storage and exporting them in any convenient format for reserve copying or any other manipulations. Naturally, the restoration of a whole SolFS storage takes more time than a single file, but, as a result, you are getting the whole working storage with all files interdependencies and directory content preserved. Such data restore operation can be executed by less qualified personal than that required for a full manual re-assembly of storage structure. In addition, use of SolFS-based storage makes possible easy separation of storage back-ups from operating system back-up procedures: quickly restore your storage independently from software operation environment.



Tier 2: Data backup with a hot site

This tier has the same provisions for disaster recovery as Tier 1, plus provides a reserve computer system (so-called hot site) at a remote physical location. The hot site is capable of handling the same data processes as the main system. Upon a disaster event, the data saved on tapes are restored on this reserve system. This approach allows faster system restoration, as only data, not the system itself, are to be restored. The use of SolFS-based storages provide significant advantages over traditional backups. Since the reserve copying of data is made separate from the system, they can be deployed in the new places faster and by less-qualified personnel. The remote site will be able to start work in less time, thus significantly reducing RTO.

Tier 3: Electronic vaulting

Tier 3 has an additional provision for some mission critical data to be constantly copied to a remote server (electronic vault) through a dedicated channel. Since a bandwidth of such constantly open channel is limited, only predefined data of utmost importance can be backed up under these provisions. SolFS allows partition of the critical data into separate storage, which will significantly simplify their transfer and later recovery. The SolFS functionality can be enhanced so that the change to data, deemed to be critical, automatically triggers data transfer through the aforementioned dedicated channel to the electronic vault. Moreover, SolFS allows multistream access to the storage: your separate subsystem can monitor the state of the critical data and transfer them to electronic vault. The integrity of the storage is not violated, encryption and access authentication are also supported.



Tier 4: Point-in-time copies

This level is different from the previous three in that the hard disks are used in place of tape. The disk have faster access time, but still need to be shipped to a remote storage location through the same channels as tape. The advantage of the SolFS in this case is that SolFS-based storages are single files, and recording of a single file takes much less time than writing of all files and directory tree one-by-one. The same applies to the recovery. As in previous case, the remote facility receives encrypted disks, making data tampering impossible. Native use of compression increases speed of writing to disks and recovery even more.



Tier 5: Transaction integrity

Retail and service organizations are ofter centered around transactions: rounds of communication interactions between the company and its customer, vendor, supplier, etc. Applications used by these enterprises are also centered on the transaction, and preserving transaction integrity between its initiation and completion is very important. SolFS-based storages support transaction integrity by default. All transactional files remain in their original context, preserve their links and interdependencies. Recovery process from such storage returns all the transactions to the time point immediately preceding the disaster. The transaction generating/managing application can be restarted exactly where it was left with almost no data lost. To increase security and efficiency, all files changed during a transaction may be singled out in a separate storage for real-time immediate backup to a remote electronic vault. The feasibility and practicability of this approach depends on the logic and design of the transaction-generating application.



Tier 6: Near-zero data loss

This level presumes existence of an application doing constant synchronous or asynchronous mirroring of data to a geographically remote server. This solution is independent of the software used for everyday business operations. SolFS storages are fully compatible with such applications and give additional advantages of faster compression, encryption, and full control over data access and authentication.



Tier 7: Highly automated, business integrated solution

The seventh, highest tier, is different from previous one in that the disaster event is automatically detected by a device(s) separate from the computer system. The disaster event triggers system restoration and activation of mirror reserve site without any human input. Advantages of SolFS storages in this scenario are similar to those described above. Regardless of the specific data recovery tier which the company will choose, use of SolFS storages gives advantages of faster recovery time, integrity preservation, data protection from inadvertent or malicious destruction and tampering while in storage, and generally reduce the requirement for highly-skilled specialist on the solution customer side.

Crashed Hard Drive Recovery

Data Retrieval from External Hard Drive

A hard drive data recovery could be accomplished on external as well as internal hard drives. You could store your significant computer data in a number of ways. Data could be stored on the removable disks, CDs, DVDs, hard drives and many other sorts of storage media or devices.

Even though there are various methods which you could use to store your data, at some point of time the electronic or mechanical storage devices are bound to break down or fail, resulting in the nightmare of data loss.

Even if the hard drive might work well for a number of years, but it could always fail when you least expect it, without any way for avoiding it.

Hard drives are the most usual ways of storing data, though they are mechanical devices and could crash or break down at any time. When the hard drives crash, you will generally lose all of your precious data, which could put you in a pretty bind. To be safe and keep yourself secluded, you must always have a good backup media, like an external hard dive.

An external hard drive is extremely handy to have. You could store all kind of files on it including music, documents, pictures, videos application files and many others. You may have an external hard drive up to the size of 1 TB.

On the data restoration side of things, external drives are great solution. You could back up your whole hard drive data on them and in case of any mishappening can restore data very easily. External hard drives work on most of the computers.

Though external hard drives are very useful for making backup and storing your precious data but eventually these too are the mechanical drives and could also fail. In case of backup failure, you may fall in grave situations of data loss and it could possibly put you out of the business.

The crash to the external hard drive could be of two types- Logical and Physical. The logical crash occurs due to file system corruption, accidental formatting of the hard drive, virus attack etc. reasons, whereas the physicl crash happens due to the physical damage to the hard drive components.

In such catastrophic situations, it becomes very important to perform hard drive data recovery to get the data back and save your business. Data recovery in these cases is feasible through the data recovery solutions available in two different forms- data recovery software and data recovery service.

The data recovery software are valuable in case of logical crash to the hard drive. These are Do It Yourself data recovery solutions, can be used very easily for effective data recovery.
