Database Backup And Recovery Plan

Design and log recovery of backup system based on Peer-to-peer cloud storage The Lu Dan of Jilin University This article has done the following work: 1. Integrated cloud storage with the ability to provide storage services and an unstructured, scalable peer-to-peer technology, a peer-to-peer cloud storage backup system is proposed, which is based on the system architecture, network topology, The structure of the system is expounded in three aspects of the overall frame structure. Using chord algorithm to coordinate multiple service management nodes, and distribute user requests to multiple data block servers, a service management node, multiple data block server and backup server form a node storage cluster, node save ...

We often hear that "there are accidents in the sky", some things happen without warning, suddenly let you unprepared. For example, I wrote an article yesterday, ready to release today, only on the computer, did not save to the U disk. As a result, the computer went on a temporary strike today, unable to start. I wait for the article, can only continue to stay in the Open http://www.aliyun.com/zixun/aggregation/12740.html "> Computer hard drive, I have to write articles again, helpless ..."

No database system can avoid a crash situation, even if you use a clustered, two-machine hot standby ... It is still not possible to completely eradicate the single point of failure in the system, and for most users, this expensive hardware investment cannot be sustained. So, when the system crashes, how to restore the original valuable data becomes an extremely important problem. In the recovery, the ideal situation is that your data files and log files are intact, so only need to sp_attach_db, the data file attached to the new database, or in the downtime ...

Until now, those who started out with cloud computing have proven the viability and management of cloud computing deployments and the benefits of cost savings, and more and more organizations are now adopting it as their core business application and IT services. In fact, with the success of cloud computing driven by software-as-a-service applications like CRM and ERP, more and more organizations are now hoping to replace traditional live backup with cloud-based disaster recovery (DR) solutions. Gartner pointed out that until 2014, more than 30% of medium-sized enterprises ...

Just a few years ago, duplicate data deletion was a stand-alone feature, and data deduplication offered an alternative to the storage systems in the enterprise backup and archiving department. It also found new uses in cloud gateways to filter out unnecessary chunks of data before entering the array or virtual tape library. Now, it has become a unified computing system of the pre-integrated functionality. Understanding how to use this technology more effectively becomes a requirement.   At the same time IT managers should re-examine storage issues and ask the vendors who provide them with storage. 1. Data de-duplication technology for backup performance ...

Following a series of business-focused technologies, including CRM, ERP, and collaboration, cloud computing has pushed its sphere of influence into disaster recovery scenarios. This is certainly good news for end users. A sharp fall in prices has also made it easier for small businesses, which have not dared to do so in the past, to prepare for a disaster recovery mechanism, as well as to bring richer options to business users. However, cloud is by no means omnipotent, and for many enterprises, the cloud base disaster recovery is not enough or even completely deviated from the demand track. In order to help you work out a set of goals with the enterprise ...

Early-adopters have demonstrated the viability of cloud computing and the benefits of managing and reducing costs, and businesses are increasingly moving their core business applications and IT services to the cloud. In fact, after verifying the viability of SaaS applications, such as CRM and ERP, in the cloud environment, many organizations are considering using cloud based disaster recovery (DR) to replace their traditional onsite backup and disaster recovery. By 2014, Gartner says, more than 30% of midsize enterprises will be using cloud disaster recovery or recovery as a service. This leads to a problem: your business to do ...
