is replicated through a TCP/IP based network environment, where the operating system process captures the changes of logical volumes. Its characteristics and storage device replication scheme is similar, can choose synchronous or asynchronous two ways, the host software and hardware environment of the consistency requirements are relatively high, the application of large amount of data has advantages. The target system needs to create a third party m

objective. It mainly refers to the data loss that business systems can tolerate. RTO refers to the maximum service downtime that can be tolerated, that is, the shortest time period from the occurrence of a disaster to the restoration of service functions of the business system.Introduction to two-party architecture and three-party architecture of the Network Backup SystemTwo-party architecture of the Network Backup System Third-party architecture of

said that more vendors, including Novell, are currently starting to provide complete and reliable migration products. A major disadvantage of traditional remote disaster recovery is the high cost. Not only is the data replication system expensive, but it also needs to increase the hard disk storage space and host system. Considering the cost of network wiring and remote data center, the cost of remote da

the system,　　Enterprise branches and service channels can automatically switch to the backup center of the network system, in a short period of time to restore the operation of the enterprise information system, to avoid the enterprise business and external services to a standstill event. The level of disaster recovery is first introduced here, if you want to understand how each level of

. Many may think that since the backup system has backed up the required data, the restoration should not be a problem. In fact, examples of data loss may occur from time to time, whether in a data center in the financial and telecommunications industry or in a common desktop system, backup data cannot be recovered. Misunderstanding 6: databases are foreign backup software, and foreign backup software shoul

While it is important to have a disaster recovery plan that includes programs that prevent replication failures, every domain controller in the core site is not responding, it is difficult to happen. The more common difficulty is due to hard disk crashes, poor network cards, file system degradation, Active Directory degradation, or a variety of minor problems that can cause damage to one domain controller.

replicating data, not automatically take over and start the application function. But a lot of users are really pursuing the seventh level of disaster-tolerant solution, that is, to automatically judge the timing of switching, automatic switching, automatic start application, and so on, minimizing the human intervention in the process of disaster-tolerant switching, reducing human error judgments. This pa

solution is the ideal choice for them. "In 2014, Microsoft has provided cloud platform services to more than 20,000 customers worldwide, with a minimum of 99.9% availability.The Windows Azure cloud has landed in China and provides a high level of cloud service to Chinese customers. Chris Crane believes that Microsoft Cloud's superior scalability, data security, and reliable data center will provide strong support for Sdro's Landing.Sdro in China is also inseparable from the strong support of pa

Data-level disaster recovery Data-level disaster recovery focuses on data, that is, after a disaster occurs, the user's original data will not be lost or damaged. Data-level disaster tolerance is relatively basic. Among them, the

consultants and software, hardware, network, resource and environment Advisor to XX Insurance company disaster backup requirements are analyzed in detail. The company has a disaster recovery strategy based on RTO, RPO, a cold backup solution, and a service level commitment. The services provided by GDS Universal data

I. Level of disaster tolerance Disaster tolerance from the degree of protection generally divided into three levels: data level, system level, business level. Data-level disaster-tolerant concerns are data that ensures that the user's original data is not lost or compromised after a disaster occurs. Data-level

resumable data transfer technology and direct analysis of database logs and memory, which is converted into SQL statements for data synchronization. This way, network dependence is achieved, this greatly reduces bandwidth costs; Due to cloud-based centralized management, fast domain name switching can theoretically be achieved in seconds. Later maintenance costs can be ignored; The cost of software procurement, most of the market's

Recovery As application availability and disaster recovery capabilities are increasingly valued, more and more companies are starting to adopt a dual-site strategy. Multi-site application availability solution technologies for geographically dispersed parallel systems (geographically dispersed Parallel Sysplex, GDPS) are also maturing, which can improve applicati

Data security is a very broad category, and simply is the use of off-the-shelf or user-defined software or hardware technology to establish a system to prevent malicious damage or to compensate for operational errors. Data backup as a way of protecting data security is a way to prevent data loss by copying data in advance. The goal of data recovery is to find and save in the computer system by certain techn

the basic concept of a disaster recovery plan, but many people do not recognize it correctly. Do you know how to get a copy of all the software after a disaster recovery, and how to rebuild a personal application? The overly assertive side might say, "It's okay, it's back u

AWS-based Remote Disaster Recovery System Architecture Disaster recovery is a technical precaution and measure that is taken back from any event that has a negative impact on the IT system .. A typical approach is to build repetitive infrastructure to ensure availability of backup capabilities in the event of a
