. Plan site recovery More and more business personnel recognize that daily access to reliable and available email systems is the foundation for their success. For many organizations, the mail system is part of the business continuity plan and site recovery should be considered when designing the mail service deployment. Basically, many site recovery solutions involve deploying hardware in the second data center. In the end, the overall design of the DAG includes the number of members of the DA

Major server hardware vendors (such as IBM and HP) provide good data protection policies (hardware or software ). redundant Array of Independent Disks is a good data protection method. for SQL Server, a detailed data backup plan can be developed through the maintenance plan. Data backup policy (full backup, differential backup and transaction log backup) Data backup is a data recovery service. Before establishing a data backup plan, you should first consider whether the backup can be used to

11.6 Designing High Availability SolutionsConsiderations for 11.6.1 PlanningThe following two factors need to be considered when planning for high availability:RTO (Recovery time Objective, i.e. target recovery times)RTO indicates how much downtime the business system tolerates each time. If the business stops too long, the loss will naturally increase. For particularly important business systems, it may be necessary to use multiple technologies at the same time to ensure rapid business recovery

event of a disaster, data can be quickly copied from a remote system to a local system to ensure business data integrity and consistency. Application Disaster Tolerance is higher than Data Disaster Tolerance, that is, a complete backup application system (which can be used to back up each other with the local application system) is established in a remote location, can also work with local application systems ).After a disaster occurs, the remote application system quickly takes over or underta

complexity of traditional disaster recovery systems, they are expensive, 80% of users' investment only protects 20% of servers, and does not guarantee service operation. Disaster recovery aims to restore the system immediately after a disaster occurs and put it into use as soon as possible. Therefore, disaster recovery uses various technologies, including data backup, data replication, and other technologies, will focus on the continuity of the business. The main indicators for measuring the

requires a very high level, using the highest security level of Database hardware and software settings and redundant equipment, the goal is not to lose any one transaction, this is because even one transaction may cause a lot of money loss and a decline in the company's reputation. The "911" incident caused 1200 companies to be affected. More than half of the enterprises were declared to collapse because IT data was damaged and lost, leading to business failures. Financial giant Morgan Stanley

offices )? What self-requirements do we have in terms of normal running time and reliability? What are our requirements for RTO/RPO, that is, the recovery time and recovery target point? After the configuration is completed, the configuration will be rich. What you need to do is to find answers to key questions that will guide us, even third parties, to design a new infrastructure that can bear the necessary load and meet the requirements of th

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 the loss of economic benefits. The major server hardware vendors (IBM,HP, etc.) provide good data protection policies (hardware o

disasters. Technically, there are two main indicators for measuring disaster tolerance systems: RPO (Recovery point object) and RTO (Recovery time object), where RPO represents the amount of data that is allowed to be lost when a disaster occurs, and RTO represents the timing of system recovery. 3. Disaster tolerance is not only a technology disaster tolerance is a project, not just technology. At presen

The major server hardware vendors (IBM,HP, etc.) provide good data protection policies (hardware or software). A well known RAID disk array (redundant array of independent disks) is a good way to protect data. In the case of SQL Server , a detailed data backup plan can be developed through a maintenance plan. Data backup strategy (full backup, differential backup and transaction log backup) Data backups are services for data recovery, so before you set up a data backup plan, consider whether

minimum switching time is about 15 seconds, or even shorter. Introduction of the disaster-tolerant solution in the same city The DS8000 Metro Mirror (MM) technology is a storage-level disaster-tolerant solution that meets the Recovery point Object (RPO) of 0. In this scheme, the data is replicated to the disaster-tolerant site synchronously by storing the underlying I/O to achieve the corresponding disaster-tolerant purpose. The DS8000 storage inte

Source: From the ancient yueju blog We have introduced the features and structure of ROS. Next we will begin to prepare for the strong Ros. On the Wiki on the ROS official website, the tutorials for new users are very detailed. It is best to clarify all the tutorials for new users. This is the most basic thing for later development. Despite this, Ros is still difficult for beginners to get started. Here, I will summarize my learning history and serve

Imagine creating a library of wikis. Wiki sites contain content that users can create, delete, and modify interactively. Many wikis feature a simple, text-based markup language for creating content. Typically, these markup languages provide only a subset of the functionality available in HTML, but there is a simpler, clearer source format. For example, text that surrounds the asterisk is formatted as bold, and the underlined text is formatted as an un

method to restore the transaction: DB::rollBack(); Finally, you can submit the transaction using the commit method: DB::commit(); Note: The transaction method of DB facade can also be used to control the transaction of the query statement constructor and Eloquent ORM.Example Assume that you want to store a knowledge point in the database. this knowledge point belongs to two different test sites at the same time, that is, the data of the test site and Knowledge Point are many-to-many relationshi

You may have heard of weblogs, but wikis has no chance to enter your field of view. Both are examples of fast-growing so-called social software-a program that encourages connections with others and communities with good health. Blogs allows individuals to post their views and interests online, wikis is relatively concentrated on website preparation and regular editing through a professional community-these people can not only paste materials on the website, but also freely edit. Recently, wikis
