changing rapidly, and the backup 24 hours ago is no longer enough to meet the demand for data growth. As enterprises deploy more and more key applications in virtual server environments, they need to implement near-real-time recovery-not from backup copies of the previous night. For example, many Exchange systems have deployed four-hour recovery node targets (RPO), and many database applications have one-hour sub-recovery node targets. Traditional ba

provided by SQL Server, let's take a look at the design of high availability policies. High Availability policy planning can be divided into four stages: Collection requirements The first step in determining a high availability policy is undoubtedly to collect business requirements to establish SLA. The RTO and RPO mentioned earlier in this article are the most critical parts. On this basis, practical expectations are established for availability r

Introduction:A template is a magical thing. Many of the code that involves a template is generated by the compiler during the compilation phase.In addition to code generation, the compiler also makes some calculations when working with templates.Using this feature of the template, we can let the compiler do some math operations.For example, let the compiler calculate the factorial instead of calculating the factorial when the program is running:Below, the Fibonacci sequence is computed at compil

Latency is one of the most important enemies in AlwaysOnLatency is one of the biggest enemies of AlwaysOn. For AlwaysOn, the primary goal is to minimize (unavoidable) the data latency of the primary replica, secondary replicas, and to achieve "data synchronization" of the primary replica and secondary replicas. The lower the synchronization latency of the primary replica and the secondary replica, the higher the reality of read-only access, and the smaller the RTO (estimating Failover Time) and

the cloud as a disaster recovery goal, companies not only need to build or rent tier two data centers, significantly reduce costs, and achieve stringent recovery-time objectives (RTO) and recovery-point objectives (RPO).Mr Xiao, general manager of Symantec Corporation China, described the Sdro as a cost-effective, flexible and easy-to-manage, one-click disaster recovery solution compared to traditional disaster-tolerant solutions. It's like a bridge

This article introduced the MySQL backup principle, welcome everybody to read. Backup is the last line of defense for data security, and for any data loss scenario, backups may not necessarily restore the absolute data (depending on the backup cycle), but at least minimize the loss. There are two important metrics for measuring backup recovery: Recovery-point objectives (RPO) and recovery-time objectives (RTO), which focus on how much time to recover

absrtact : The traditional data backup technology has the problem of backup window, recovery time objective RTO and recovery time RPO too long, which can not meet the requirement of data protection for enterprise critical business, thus the data snapshot technology is produced. In this paper, the concept of snapshot technology, characteristics, implementation technology and the status of the development of a general exposition, and the future developm

addressing San issues, such as slow, storage growth exceeding control, and unsustainable migration costs, are turning to tiered storage and taking the following measures: Clearly define recovery point objectives (RPO) and recovery time objectives (RTO), and use this as a basis for data placement (a level of service that is relative to business-oriented and without clear objectives); Communicate these requirements with the business unit to allow the

--this has actually gone beyond the concept of data disaster tolerance, and achieved the application level of heat-temperature mode of disaster tolerance. Similarly, the Beijing Center's data are transmitted remotely to the Shanghai center, creating a disaster-tolerant model in which any catastrophe can be temporarily taken over by another site. The specific implementation process is as follows: 1 First, in Shanghai Local data center with SEPATON S2100 ES2 vtl Replace the original STK mechanica

applications, data loss is unacceptable. Because of the slow performance of OLTP applications due to the network latency between master and slave, there is no synchronous replication between master and slave (despite PostgreSQL support, this is better than MySQL). Since the strong consistency between the master and slave is not guaranteed, database loss may occur during switchover, affecting RPO. At the same time, the use of local disks makes the c
