If you are a heavy reliance on Internet, you will find that there is enough ill will. Especially when you want to book a romantic trip to the goddess found ctrip hung up; finally boarded the ctrip found baowan afford a strike; watching goddess to go back, want to know ask when you suddenly realize know stayed down..
All kinds of server failure after another in recent months. According to ctrip earnings estimates, ctrip downtime losses this year to about $ 1.06 million per hour. For Web site operators, to lose money is undoubtedly the biggest real money "disaster". Fortunately after has more than 10 hours of efforts, was physical damage of data and recovery again, this back relies on of is website core information of backup information; two months Qian paid treasure due to fiber was dug broken was forced to switch server and terminated service number hours, Alibaba in "Summary" statement in the said: future of target is "in switch Server Shi, as do let user minimum perception even no perception. "From its formulation is not difficult to find, not to force for hardware, people are able to tolerate, and sought to ensure the continuity of the business is their pursuit.
Enjoy the movie, Super Marine who have affectionate memories of the movie the last detail: the hero Hiro left by relying on chips, to recreate a beloved friend comes to light. Yes, this is cloud disaster recovery business to remind you: "backups are important, Oh"
How can I make Taishan collapse in front of your server without it? Lei Feng also interviewed earlier the British software provides disaster recovery services, here are the brain hole big time.
Backup set
If you care about a collection of security as a Japanese teacher, let what happened to learn enterprise backup. For businesses, more core data will deploy on the server "between the three centres" cloud backup solution.
The so-called three-Center, generally refers to the local servers, backup servers, and cloud backup server. The local server and the backup server in the same city, and cloud backup server can choose in other cities. This security level in theory enough to respond to major disasters or extreme situations such as war. Michael Kors iphone 5 cases
"Our backup servers is their product: the British machine, everybody said business office more secure, so we put the backup in the accounts department. "British software CEO Hu June q" account "," backup in the cloud and our aliyun Hong Kong servers. "
For most Internet companies, even this level of user, and are similar in logical form deployment. If the primary server is having problems, you can quickly switch to the standby server, encountered major problems, such as widespread power outages, disasters, cloud backup is only used.
According to this logic, personal important information and, of course, should make a local backup, and then upload storage in the cloud. However, lack of the automatic synchronization of enterprise-class software, manual synchronization requires a lot of time and frequency is cannot be guaranteed. Enterprise-class backup software for this question is how to do it?

So much data, the Minister qie can't do
"For banks, the daily amount of data generated is enormous, if using a traditional full backup mode, open from after work to get time to upload all data before was not enough. "Hu Junqing said.
Data backup on the cloud today a stream overwrites the data yesterday, is the most reliable way to backup most people can think of. However, subject to bandwidth constraints, this classic play "the Minister qie" can't do it a long time ago. Cloudy disaster recovery business had taken slightly more aggressive "we comin" method: by comparing the difference between the two days of data, like the "patch" adds a new data accurately, so that the data and the local synchronous updates. In this way, the total amount of data transferred is very small, for bandwidth pressure nosedived.
Hu Junqing believes that patch size of the learned, and this can reflect precisely the technology is different. His network from Lei feng, "British cloud solutions at the source (local) identify data differences, these differences did not file or with block as a unit, but in bytes, this technology is the core of British pride cloud technology. "

Recovery of "particle size" is an important indicator
Cloud backup technology is not only used to back up, sometimes used as a synchronization of information distribution, which brokers embody is particularly evident. For example, from the Trade Center stock market data be synchronized in real time to various outlets, this requires minimizing delay and detecting data changes in real time.
British Software CTO Zhou Hua said: "some data varies with the server, has strict requirements for synchronization, such as access to a large quantity of electricity or trading platforms. "Between each synchronization interval, called the" granules to recover. " Smaller particles, means that the higher the frequency of synchronization, when a disaster when, before restoring the data closer to the downtime data.
Here is the quiz time. Children's shoes, guess it enterprise services back to how small the particles? One day? An hour? A second? Tremble of mankind! "As a result of byte-level replication of data, the total amount of data you can control, so the British side the cloud particles can be controlled in one out of 10,000 seconds. "In order to emphasize British cloud technology, Zhou Hua deliberately added.
Manual backup movies do you think that human technology has been playing God, filled with thousands of server in-place reorganization of hundred holes full resurrection of that vision?
"Disaster year"
"Synchronization is a threshold, which involves extremely segmentation algorithm, which is the consensus of cloud disaster recovery business. "Professional evaluation. Taken together, the disaster recovery software all the effort, all in order to achieve disaster when, simple recovery of precious data on the server as accurate as possible. Major companies also recognize that in such a fierce competition, if the core data is damaged, is likely to recover, shameful heaven behind.
"Disaster is the last line of Defense for enterprise security, this is hard and needs, if it is done well, are very promising. "Ivy-cloud security services spokesman said of domestic. Data show that 60% of business and individual end users are currently using cloud or cloud deployment strategy, HP, IBM, Symantec and other veteran disaster recovery vendors are also in competition for the Chinese market, visible cloud Dr outbreaks can be expected.
2015 cloud security industry known as "disaster year", believe that the server will be more and more strong, not because of a cable fault or the switch hang into the ICU to rescue. Dear information as white as dead, no longer is a fairy tale.
