Scene: Toward virtualized data backup restore big different

As the application of http://www.aliyun.com/zixun/aggregation/13883.html > Virtualization technology becomes more and more deep, the way of data backup and restore is very different from the past. For example, data backup restore for VMware virtualized environments. This is not only a technological change, from the backup software of the industry's ecological environment, you can see a different scene than in the past.

The backup software industry is relatively stable, the main competitors have not changed in the past few years, although some of the emerging storage technology to ask the city, such as VTL (Virtual Tape library), but these do not completely replace the original backup software, so the status of several major backup software vendors are not shaken.

However, after the virtualization technology has been widely used, the backup software market is not in the quiet, many newly-created backup software companies emerge. These new companies are designed for virtualized environments, and once the vast majority of the enterprise's IT environment is shifted to virtualized environments, the new backup software might have the opportunity to subvert the current mainstream backup software. Of course, the old manufacturers who dominate the market for many years will never sit idly by, and many innovative designs have been made for the characteristics of virtualized environmental data protection.

Emerging backup software vendors have the opportunity to take advantage of the gap, the backup from virtualization is different from the past. However, virtualization has been popular for many years, why have people recently started to talk about the backup of virtual environment? Because as virtualization becomes more and more used, backup starts to become a big problem.

The biggest selling point of virtualization is to divide an entity server into multiple virtual servers, and the more virtual servers there are, the higher the utilization of resources. In the beginning, the number of virtualized servers, so the traditional way of backup can be completely resolved, but as the level of virtual machines to upgrade, the traditional way in each virtual machine installed Agent program, began to appear laborious. When backup time is up, all virtual machines start to perform backups, not only the processor computing resources, but also the load of data I/O will be too large to the system to cope with, and may not be able to complete the backup within the scheduled time.

To solve this problem, there is the practice of handling backups from the hypervisor level, and since then, the way in which virtualized environments are backed up is quite different from what we've known about backup over the years.
