SQL Data Recovery

Recovering Data From Microsoft SQL Systems

Business systems are usually made up of databases. There are databases for customers, for accounting and for product design. One of the more common database systems are Microsoft SQL Servers. This robust and dynamic system provides a solution to a company’s business system.

The data that is inside a business database is valuable and so is the database itself – it can take weeks or months to set one up completely. When a Microsoft SQL database cannot access the data, your client’s solution is Ontrack Data Recovery services. Using specialised tools that we have designed for Microsoft SQL recoveries plus our Ontrack Remote Data Recovery (RDR) service, you have a strong data recovery solution.

SQL Data Loss Situations

Data loss situations can occur at a number of different levels. The first level of data loss starts with the storage device. This can be a single hard disk or a SAN or RAID storage array. If loss is at this level, the Ontrack goal is get the storage device operational so that the data can be copied off. Ontrack clean room engineers work at an electronic and mechanical level to get the device operational. If the storage device is a SAN or RAID array, the goal is to get that storage device operational and the data copied off. SAN and RAID arrays add a challenging level to the complexity of the job. Ontrack has excelled in specific techniques to handle these storage devices.

The second level of data loss can start at a file system level. The file system is a unique method of storing and organising system and user files. The operating system controls the file system. If the information about where data files are on the volume are damaged or lost, then adjustments or repairs need to be completed at a file system level. Once the file system is repaired then the file’s data stream can be accessed correctly. Most operating systems have a utility that will automatically fix the file system. These utilities work to make the volume accessible. However, this can permanently damage the data stream of the file.

The third level of data loss can occur within the file itself. As previously mentioned, .MDF files are quite complex. The internal structure can be corrupted to the point where the DBMS will not make the database available. This is where Ontrack excels in providing a total data recovery solution.

Ontrack Solutions to SQL Data Disasters

Ontrack has the solution to corrupted or damaged Microsoft SQL database files and we can use our Ontrack Remote Data Recovery technology to get the data back as fast as possible. The internal Ontrack internal Microsoft SQL recovery toolset was designed to retrieve the data contained within the .MDF file.

The process of a Microsoft SQL recovery begins with finding the database file requested. If the database file is inaccessible due to problems with the storage device, then we work to get that data extracted. If the file is missing, deleted or truncated due to problems with the file system, then we work to adjust or repair the file system to correctly point to the data stream of the file. And finally if the file system has no pointers at all to the file, then we search the entire drive looking for Microsoft SQL data.

The next stage is to work on the database file itself. This is where the Microsoft SQL toolset comes. These tools analyse the complex internal structures of the .MDF file and provide reports as to what tables are recoverable. The reports also list the number of data rows that will come back.

Once the evaluation is complete and authorisation is given to recover the data, our Microsoft SQL toolset will copy the data into another Microsoft SQL server database. After this phase is complete, we can backup or archive the recovered data.

Remote Data Recovery is the fastest solution for Microsoft SQL recoveries. The Remote Data Recovery process will copy the recovered data into a Microsoft SQL server that is setup on you or your client’s site. They only need MicrosoftSQL server running. For best results we recommend that the storage device we are working on be connected to a Microsoft SQL server, because all of the data transactions will be occurring on a single machine.
