What disaster recovery backup technologies are available at present?

Traditional disaster recovery backup schemes are mostly based on remote replication technology. Remote replication refers to the use of replication technology to store data in a remote disaster recovery center in a synchronous or asynchronous manner. There are three main ways to realize it: 1. Remote copy of software or hardware by host. 2. Use the replication software of the storage itself. 3. Use database software products. Remote replication can achieve data-level disaster tolerance, but once a disaster occurs, business continuity cannot be guaranteed. In addition, once there is a logical error or human error in the database, remote replication cannot repair the data error, nor can it retrieve the mistakenly deleted data, let alone 100% recover the data to ensure the availability of the data.

In 20 1 1 year, SNIA, the global storage network industry association, released a research document on CDP continuous data protection technology, which broke the traditional pattern in the field of disaster recovery and backup. The only product in China that meets SNIA's definition of CDP is the excellent disaster recovery backup software of Heli Memory. With CDP continuous data protection technology as the core, a full-demand platform for files, databases and applications is built on a remote desktop or server, which can not only prevent data loss and repair data errors, but also ensure business continuity and fully meet different data security and business continuity requirements.
