Data Recovery after Physical Crash of Database Server
A database server can be a computer or a computer program running on a database server computer. The server computer processes user requests of various client systems over a network and takes care of all incoming and outgoing data (large number of transactions, database updates etc.) due to its capability of efficiently handling multiple user requests at a single point of time. The database server software (as Oracle, SQL Server, MySQL etc.) provides database services to other programs or computers over a network based on Client-Server model. There are various Server operating systems and database systems available to meet such requirements. Some of these are Microsoft SQL Server 2008 on Windows Server 2008, Oracle 9i R2 on Windows Server 2003 R2, MySQL 5 on Red Hat Enterprise Linux 5/4 etc. Due to voluminous request processing, continuous operation, heavy information exchange, system software faults, virus infection, malicious intent, security breaches and more, such servers encounter hardware or software level crashes. The software level crashes are easy to handle as the inaccessible or lost data can be recovered by using Data Recovery software and the corrupted server database can also be repaired and restored by database repair tools. In these cases, all data from the lost database can be recovered by consulting and sending the hard drive to Server Recovery firms that follow component level practices to recover lost and inaccessible data from the physically crashed database server hard drive(s). The server hard drives are scrutinized for the cause of crash as in most of the cases the cause of crash is not known. A physically corrupt hard drive needs to be fixed first to make it accessible. So, the Database Recovery Services providing professionals fix the hard drive in situations like read/write head crash, actuator arm malfunction, spindle issues due to wear and tear etc. After fixing such issues and making the database server hard drive accessible, the recovery experts create drive images to safely extract the critical server data from the database server drive(s). The approach ensures completely non-destructive and secure recovery from the database server hard drive. The Database Recovery Services is performed under sterile and controlled environment of Clean Rooms which are laboratory environments free from environmental factors like dust particles, humidity, ESD (Electrostatic Discharge), excessive heat or pressure etc. Stellar Information Systems Ltd. provides best quality Database Recovery Services for all types of database servers. At Stellar, the state-of-the-art recovery services are performed under Class-100 Clean Rooms with no room left for doubt or procedural errors. We also provide recovery solutions for other Servers like Domain Controllers, RAID, NAS and SAN. We cover almost all the makes and models of hard drives including SCSI, SATA, EIDE and IDE.
