Cloud Backup and cloud storage 6 aspects you should know

Although "cloud" has no intelligent hardware, O2O so popular, but this does not prevent "cloud" become the darling of 2B market. Until 2010, most companies thought the public cloud was not fully mature, still not trust it as the main storage of enterprise data, backup, but 2010 years later, as the giants of the accelerated layout, as well as large data of the great heat, "cloud" has become the capital of new objects, according to statistics, in 2014 only a year, There are 1.265 billion dollars in the market for cloud computing, which is not the investment of the Giants themselves.

When it comes to cloud computing, we have to mention two important applications in cloud computing: Cloud backup and cloud storage.

Today, let's talk about 6 things you need to know when using cloud backup and storage services.

1, the cloud is private, so should do a good job of investigation

Whether you think so or not, almost every cloud service resides on a private platform, which means that as long as you buy any cloud service, you are bound by the vendor, and in the cloud storage and backup services, so before you decide to dump important data into the cloud, The services provided by the cloud should be thoroughly investigated and evaluated to investigate the impact of the private properties of the service on your entire storage and backup environment, survey platform, and interoperability support. For example, some cloud vendors only support Windows and Linux platforms, and if you want to use UNIX, that's a huge hurdle, and finally investigate whether your storage and backup software supports the cloud provider's service interface.

2. Send the third copy of the data to the cloud

It is highly recommended that companies that have just started using cloud storage and backup services send a third copy of the data to the cloud, major backup software vendors have started to integrate cloud services APIs into their own software, and if your backup software does not yet support direct interaction with cloud services, then you can only replicate data in a traditional way. Once the data has been copied to the cloud, evaluate how to access the data and the security of the data. It is worth mentioning that there are already a number of SaaS applications such as multiple backups that specialize in cloud data backup.

3, look at their network bandwidth enough

To store and back up data in the cloud, first evaluate your own Internet access bandwidth, how much bandwidth does it take to satisfy your need to access the data in the cloud? This question must be answered. When storing and backing up data locally, the network latency of the local network is almost negligible, but after switching to the cloud, this is an important issue. Imagine the notion that access response time has suddenly become 20-30 milliseconds from less than 10 milliseconds, yes, cloud service provider network bandwidth is also important, but usually the other side will provide enough bandwidth to ensure the user's use, the key depends on their network bandwidth enough. More importantly, your local network is often shared by multiple businesses, which means that cloud access communications must compete with other Internet access communications for bandwidth, which can be a huge challenge during peak business hours. Storage traffic is quite alarming, if not asynchronous way, can cause network serious congestion, the cloud as a backup target, need to schedule backup task execution time, preferably in the business trough period. At present, many backup software has provided the backup time, backup number of independent choice, such as the above mentioned multiple backup.

4. Private cloud or public cloud

The question of whether to use a private cloud or a public cloud has long been debated, and people always think that the public cloud is insecure or that there is no private cloud security. In my opinion, first of all, security is a relative concept, that is, the so-called no absolute security; second, the private cloud has not only a security problem similar to that of a public cloud, but even some private cloud itself is built on a private cloud. From the perspective of storage and backup software, a disk array serves multiple applications on multiple servers, and if there are special requirements that require independent control of the storage, you must contact the cloud vendor for isolation, and of course the cost of doing so should increase.

5. The challenge of remote network file sharing

The idea that many companies using cloud services allow their users access to web directories or files shared through the cloud is good, but one big challenge is that Internet exports may increase four times-fold. Increased traffic leads to network congestion, which in turn increases network latency. Normally, file-sharing traffic occurs on the local network, and any problems can be resolved quickly. And go to the cloud storage, the number of stakeholders involved in network issues has increased, including cloud providers, ISPs, and the enterprise itself, which can lead to longer problems and ultimately a strong user backlash, so scale is important if you plan to move the entire organization's business data to the cloud at once, So first of all, we should study the impact of its failure, I strongly recommend that you take a unified planning, distribution and implementation of the principle of one shift.

6. Cost per gigabyte

Large numbers of users have questions about the changes in storage and backup costs per gigabyte. If you look at the first five questions carefully and think carefully about the potential costs of maintaining the cloud storage and backup strategy, it is easy to answer the final question: moving to the cloud can have a significant impact on the cost per gigabyte. While the cost per gigabyte is low in terms of peripheral costs, which can shift the cost of capital spending to operating costs, you may be secretly happy, but the full cost per gigabyte is likely to be higher if all the problems mentioned above are resolved.
