Today, cloud computing is so hot that it has a wide range of data protection measures, but there are problems with security, bandwidth, connectivity availability, and data recovery in a technology that everyone is chasing. In the face of these problems, the inventors of the field are not sitting still, using a mix of traditional online backup system performance and cloud storage to form a hybrid cloud backup, or disk to disk to cloud computing (D2D2C), which is transforming cloud computing into the now accessible, practical data protection infrastructure component. In this case, the user can enjoy the advantage of both--while the online component captures and stores the data at high speed, the old data is moved clouds.

What is a hybrid cloud backup?

The emergence of hybrid cloud backups is a way to connect both traditional backup and cloud computing to inexpensive, offline, and unrestricted capacity. A hybrid cloud backup solution may use a certain amount of disk space in the form of a local cache, which is often used as a staging area for data, and soon data is sent to the cloud. Store the accepted data on disk so that backups can be captured at high speed, then the backup software or the D2D2C device encrypts and transmits data to the service provider. Then the full backup is transferred, and the oldest backup data may be discarded to make room for the new data, but the most recent data will be retained to speed up data recovery operations.

D2D2C Solutions

In fact, there are a number of hybrid cloud backup tools available, including traditional backup suites, which take local disks as objects and eventually move data to cloud computing. Almost all backup software vendors have or are working on such solutions, such as Acronis Inc., CommVault BAE Inc. and Symantec Corp.

But one of the most interesting inventions of late is cloud backup devices. These devices typically use dedicated hardware to optimize the amount of data transferred and reduce the space used in cloud computing for data duplication, compressing and applying WAN optimization techniques. These hardware devices allow backups to be passed into the cloud via the right Internet connection bandwidth, while optimizing the day-to-day cost of cloud storage. This cost is often priced according to the amount of data stored and transmitted.

There are many general-purpose cloud storage devices on the market that can be used as backup objects, including from Ctera NX Ltd., Cirtas Bae, Nasuni Corp., Storsimple Inc. and Twinstrata Some of the devices in Inc. are in the development phase. Other dedicated cloud backup storage devices that have good integration capabilities and performance in backup--riverbed Whitewater is an example of this.

Advantages of hybrid Cloud Backup

Hybrid cloud storage technology brings compelling promises, most commonly the complexities of dealing with offline data protection. Hybrid cloud storage affects the existing backup and recovery infrastructure and seamlessly moves data offline without additional data backup, tape output, and/or transport activity. In addition, because most solutions are stateless and have direct access to cloud data from new locations, it is often possible for disaster recovery (DR) to improve the accessibility of offline data. Some products can even allow cloud applications to access data in the cloud in the event of a disaster, making it possible for cloud computing to have Dr capabilities.

Some users are faced with operational constraints, with only limited physical devices supporting the growth of the backup system, or a hybrid cloud backup when they want to reduce power, cooling, and other physical maintenance conditions. In this case, a hybrid cloud backup can greatly simplify your backup infrastructure, freeing you from shipping costs to pay for "on-demand" cloud storage.

For each type of user, the secondary advantage is also obvious, and they are as important as the user's primary advantage. For example, the idea of infinite preservation, cloud computing through its own near infinite expansion of the ability to make it possible. Coupled with the common data duplication technology in devices, cloud computing can easily be used as a repository for more data, while optimizing data footprints to minimize capacity overhead. Another advantage of turning to cloud computing for capacity issues is that it eliminates cyclical upgrades and ends painful data migrations.

The advice of the mixed cloud

While the advantages are compelling, most users still have concerns about cloud computing. However, vendors are working to address the problem of these entangled cloud backups, for example, to provide encryption for data transmission to handle security issues.

Another problem is that it usually takes a long time to move backups to the cloud, especially to move the original dataset. Although optimization can reduce the total amount of data across multiple backups, the first backup still takes some time to replicate to the cloud for complete protection. Similarly, when a disaster or device failure occurs, restoring data to a new device may slow down due to the amount of data recovered. However, recovery through limited bandwidth may still be faster than getting offline tapes. In any case, evaluate how the cloud backup strategy supports your recovery time and recovery point objectives.

In the face of the challenge of traditional remote office data protection, hybrid cloud backup should not be considered as a perfect and simple universal medicine. Currently, devices on the market cannot access the same storage cloud at the same time, nor can they eliminate duplication across devices. This means that backups from two sites can be inefficient and consume more bandwidth, and backup data cannot be shared easily by multiple devices on different sites. Attempts to make multiple branch office backups through a single hosted Internet connection can cause problems with bandwidth utilization that can complicate problems if a single, unified, protected copy of the data is required for electronic search, compliance, or other purposes.

The future of hybrid cloud backup

Hybrid cloud Backup technology is no doubt up-to-date, and its advantages include "no intervention" management, low cost, flexibility, and built-in disaster recovery (DR). These factors are driving the market to develop in this area, and it is worth mentioning that the recent Taneja group's emerging market forecasts that the hybrid cloud backup solution will grow at a compound annual rate of more than 80%, which will create 300 million of billions of dollars in backup products by 2014.
