The built-in data protection systems in an SQL database server cannot fully meet the data recovery requirements in such systems. Even in the presence of other data protection systems, hard disk failures, power outages and other accidental failures can cause corruption of master data files and backup files of an SQL database.
At such moments, the work of the database supervisor becomes crucial. He must ensure that the database starts working as soon as possible. He knows that the organization cannot tolerate data loss due to database crashes. It is most critical when the data impacts business results or relationships with customers.
Most database supervisors know that even minor corruption of master data files can cause major damage. DBMS (database management systems) have sufficient protections to protect important company data in the database. However, it is still possible for the backups and transaction logs to become corrupted. Wise supervisors always consider the role of commercial software available for data recovery.
Such software is easily accessible in markets in the form of customizable packages. It is offered by data recovery consultants. Some companies also offer them as software or as a service. Available software is usually placed on the company’s website. Web-based software is useful for companies with large databases and operating in a distributed environment.
By using such software, you can recover data from the following things.
• From damaged RAID (Redundant Arrangement of Independent Disks) hard drives
• Damaged or deleted indexes
• Partially corrupt table data
• Damaged foreign keys or locked databases
• All editions of the SQL servers
Generally, the time it takes to recover data varies between one and four days. This depends on the amount of data that has been corrupted and the reason for the database crash. Therefore, this software recovery tool is effective protection against power failure, database crashes and accidental operations.
