destination, the driver must return a message at the start point, this is just like the TCP protocol sends an ACK response to the source end after receiving the data. The driver can run back without a car (send an ACK response packet separately ), you can also bring some return messages to the destination region (TCP can include ack response information in reverse traffic to improve efficiency ). However, in a disaster tolerance system, data is alway

Background:Our server environment, is the ESX server, which ran dozens of virtual servers. Most of them are virtual Windows servers, and then each application will have several app servers and then install WebSphere to build cluster to support the Web server, both IBM HTTP server and IIS.The environment is like this, this time for a region of the server cluster to do disaster recovery drill.So-called

Disaster recovery and Clustering (1) in the previous article: Microsoft Distributed Cloud Computing Framework Orleans (1): Hello World , we probably know how to use Orleans, of course, the previous example can be said to be simple and invalid, because with Orleans can not write only a Hello World, Orleans is for the distributed and cloud computing framework, then today we will briefly say that

in data modification Transaction Log in SQL Server (III)-Role of log in simple recovery mode Transaction Log in SQL Server (IV)-Role of log in full recovery mode Introduction Logs ensure durability and data consistency. You can use logs to Undo and Redo data. Therefore, using logs, SQL Server can not only achieve disaster

The database has now become the cornerstone of the enterprise, so it is necessary to ensure the high availability of the database. At the same time, it is also necessary to prevent unexpected incidents from causing problems in the entire data center (such as addresses and floods ). Therefore, data center high availability and disaster recovery must be considered at the same time. Using SQLServer's database

In the Hyper-V Environment, Microsoft provides three solutions for disaster recovery. Based on the traditional WindowsServerBackup, it provides SystemCenter-DataProtectionManager for data centers and WindowsAzureOnlineBackup based on public cloud services. I. WindowsServerBackup Windows Server backup is composed of Microsoft Management Console (MMC) management units, command line tools, and WindowsPowerShel

If you're like most administrators, you might be responsible for backing up your Exchange database every night and storing your backup records in a secure location. This is great--but just taking these steps may not completely get you out of a serious disaster. In this article, I'll describe three of the most important and best ways to make a disaster recovery fo

Active DirectoryThe importance of Active Directory disaster recovery is self-evident for system administrators. Active Directory is one of the most critical services in Windows. To avoid downtime and productivity loss, developing an effective disaster recovery plan for issues related to Active Directory is crucial. Thi

data, as in the case of aof logs. So every piece of data just needs to be written once.Another reason is that the Rdb file storage format and the Redis data in memory encoding format is consistent, do not need to do data encoding work, so the CPU consumption is much smaller than the AOF log load.Second, disaster recovery simulationSince persistent data is used for data

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

mechanism, the client may read the old data in the standby node, if the business requires strong data consistency, you can set the read-only main option in the read request, so that the read request will be forwarded by the interface layer to the master node, in this case, the standby node is only used for disaster recovery, not provide services.In order to ensure the data consistency of the primary and st
