On the one hand, their functions are getting greater and greater, and enterprise operations depend strictly on the normal operation of IT systems. On the other hand, as IT systems are becoming more and more complex, the data vol

Disaster recovery is an unpleasant topic, but it must be addressed. Taking a company's email system as an example, some companies will back up past emails, probably every day or every week, after a disaster,Although the backup data can be restored to the system, this periodic backup only ensures the security of the backup data. The data between the last backup an

With the rapid development of office automation and electronic commerce, the dependence of enterprise on information system is more and more high, and database plays an important role as the core of information system. Especially in some industries with high data reliability requirements such as banks, securities, telecommunications and so on, if there is an accidental downtime or loss of data will be very heavy. This database administrator should develop a detailed database backup and

[Introduction] The familiar melody in the mobile phone sounded, and the call was triggered, but the news was unpleasant: An emergency fault, a disaster where the customer accidentally deleted the ad object, and a total of more than computer accounts were deleted by mistake, it involves many production systems across the country. If it is not processed in a timely manner, large-scale business paralysis will occur. Without delay, we were immediately "ar

HP-lefthand underlying structure details and storage disaster recovery I. Features of HP-lefthand HP-lefhand is a very good SAN storage that uses the iSCSI protocol to allocate space for clients. It supports RAID 5, raid 6, and raid 10. It also supports volume snapshots and dynamic volume resizing. Common models include p4500, p4300, and p4000. Based on the disadvantages of market share and software-defined

SQL Server backup and disaster recovery The data processing becomes more and more important in the modern enterprise operation, more and more crucial, may even become the enterprise development bottleneck. The importance of data protection is self-evident. If an enterprise does not have a good data protection program or strategy, once the important data loss, the consequences will be disastrous, along with

restoration process of the Oracle database is divided into two steps. First, all the retries stored in the redo log file are applied to the data file, and then all uncommitted transactions in the Redo are rolled back, in this way, all the data will be restored to the time of the disaster. Database recovery can only be used to redo data files before a fault occurs, restoring them to the time of failure, rat

Brief introduction The role of the log is to ensure persistence and data consistency, through the log can achieve data undo and redo, so through the log, SQL Server can not only achieve disaster recovery, but also through the redo of the log to achieve high availability. This article focuses on the role of logging in several high-availability scenarios provided in SQL Server and in
