recommended disaster recovery backup system. It can back up data (including databases and files) to the backup machine in real time and incrementally. Unlike the image and snapshot modes, it can continuously record the data change process, similar to a video recorder and performing any point rollback, this is the true CDP (true CDP ). Different from the dual-Host Architecture, the

Through this article, you will learn about DB2Hadr functions and basic operating principles, you can quickly configure an hadr environment through an instance and perform some simple functional tests. Next we will discuss some technical points of hadr.Discuss in detail and give some suggestions. If you are considering the HA issue, I sincerely hope this article will help you. DB2 hadr Overview High Availability disaster

Cloud disaster tolerance, as its name implies, is a cloud-based Disaster Tolerance System, which can be either in a remote location or local location. The cloud disaster recovery system integrates the advantages of a local ha (High Available) system and a remote disaster

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

database applications and O M, in addition to database status and performance monitoring, database backup has never been well managed by tools, DMB database monitoring and disaster recovery systems were born to solve this conflict. In the DMB system, there are a total of 7 backup modes in the backup configuration. Next we will introduce them separately. Under what circumstances should we select the backu

Alter database open read only; Alter database recover managed

cost of synchronous replication backup is quite high. In the commercial storage field, the 25 GB synchronous storage service may need between 150 to more than 500 USD per year.You can use the following methods to ensure that these high-cost technologies are free of charge: One Google Data Center supports millions of users. Therefore, the cost shared by each user is much lower. Google's standby data center is not enabled in the event of a

Environment product: DB2 UDB Platform: cross-platform Version: 8.2 (8.1 patch 7) Problem DB2 UDB High Availability disaster recovery (HADR) is a database replication feature that provides high availability solutions for partial and entire site faults. HADR copies data changes from the source database (called the master database) to the target database (called the backup database) to prevent data loss. This

volume for replication. Its features are similar to the replication solution based on storage devices. You can also choose synchronous or asynchronous modes to ensure high consistency of the host's software and hardware environments, it is advantageous for applications with large data volumes. If the target system is readable, a third-party image must be created. I personally think that this technology is more suitable for systems with large data volumes or

Redis uses memory to play a high-performance read and write in many scenarios, but the Redis itself is still a stand-alone database, if the system is strongly dependent on it, then still must do the necessary disaster tolerance, for this problem, there are several strategies: One, m/s switch Because Redis is a stand-alone database, some disaster-tolerant scenarios for MySQL can also work well, such
