Turn clouds into rain, backup first. It is precisely because of the low cost and strong flexibility of cloud backup, some small and medium-sized enterprises have begun to try. Even some large enterprises are prepared to use cloud backup to fill some gaps in data protection strategies to face budget constraints, personnel vacancies and other problems. Therefore, everyone should have a correct understanding of cloud backup technology itself, and at the same time, we should also be soberly aware of whether the enterprise's own IT status is suitable for backup to the cloud.

Cloud backup: what are the advantages?

Scalable and cost Savin

After using cloud backup, enterprises can rely on the unlimited expansion capabilities of third-party cloud providers without worrying about investment. In fact, the pay-as-you-use model reduces the annoyance of backup procurement and implementation. This approach enables us to predict and manage capacity growth and operating expenses.

Efficient and reliable

Cloud providers often provide state-of-the-art technologies such as disk-based backup, compression, encryption, deduplication, server virtualization, storage virtualization, application-optimized data protection, and so on. In addition to the security required by certification, most providers can also provide 7x24 monitoring, management and reporting, such as a domestic saas application: multiple backups. The average company may not be able to afford these capabilities.

Reduce recovery time for small amounts of data

When recovering from a tape, the administrator needs to find the tape, load it, find the location of the data, and then recover the data. Recovering data from the cloud is much faster; it does not require time to transport tapes, dispose of, and find tapes from tape storage points. The data that needs to be recovered is found and transmitted over the wide area network (WAN), saving time and eliminating the need to build local tape equipment.

Usability

For companies that cannot afford a disaster recovery architecture, or can afford it, but realize that outsourcing can improve efficiency and reduce costs, cloud backup may be attractive. Copies of off-site data can be accessed through any Internet connection or device, increasing the insurance factor in the event of a regional disaster.

However, cloud backup is not without shortcomings!

Backup data and full recovery

Depending on the capacity of all data, the first full backup and full recovery of data may be too time-consuming and have too much impact on the production system.

Size limit

Based on the available bandwidth resources, each company has a reasonable threshold for the amount of data that can be transmitted to the cloud every day. This restriction has an impact on the backup strategy.

Termination of service

Understanding the best roll-out strategy is as important as reviewing specific features. Indicators to be considered include service termination fees, early exit fees, cancellation of service notifications, data retrieval methods, and so on.

Cloud backup: are you suitable?

Companies should correctly evaluate the challenges they face, their capabilities, and the assets they have, which will help you determine whether a cloud-based backup strategy is better than continuing to rely on full indoor backup. Here are a few aspects to consider:

Budget

You might as well make a comparison between indoor backup and cloud backup: for tape backup strategy, there are indoor hardware and software maintenance fees, media procurement fees and storage fees, while for hybrid cloud services, you have to spend three years on operating expenses.

The amount of data that needs to be backed up daily

How much data needs to be protected (based on total data capacity and daily data change rate)? How often do you need backups to meet your recovery goals? Calculate how much data you need to transfer in terms of the amount of data per day, and whether these transfers can be done in the backup window with the existing bandwidth.

Blank area of data protection

Do you have any new instructions to improve data protection in ROBO or other terminals? Do you have the staff and capital budget to invest in these new initiatives? Do you currently have a DR strategy? If so, do your people, programs, and techniques allow you to meet your recovery time objectives (RTOs) and recovery time point objectives (RPOs)? Using a cloud backup vendor to expand existing indoor data protection (no advance payment for facilities and no additional personnel) may be more cost-effective than expanding existing indoor equipment.

System architecture

Does the current system architecture limit the satisfaction of organizational needs? Does the lack of budget prevent you from keeping up with technological progress? Are you going to update your technology soon anyway?

Service level agreements (SLA) and the need for legal compliance

Can you complete the data backup within the specified window time? Do you complete data recovery within the agreed time limit? If not, is it because the technology is out of date or because there are not enough operators? Can you meet the regulatory needs of the company and regulations with existing personnel, procedures, and technologies? Does your maintenance of copies outside the device introduce possible security risks? If your data recovery service level agreement (SLAs) is more stringent than streaming data over WAN links or physical removable disks, then cloud-based backups may not be suitable for you. If you don't have the discipline and ability to meet your compliance goals, it's possible to outsource data protection to a vendor that supports compliance.

Staff level and degree of specialization

Does the current economic environment affect you to have enough staff for data protection? Is your current backup / recovery architecture too dependent on the employees you work for? Do you have in-house experts to properly build and maintain data protection architectures and programs to meet your current and future goals? Operators are often the most expensive aspect of data protection, so it may be more feasible to introduce data protection capabilities that do not require additional staff.

With a clear understanding of cloud backup and the state of the enterprise, the next step is to determine the implementation of cloud backup, but we still have to choose a reliable cloud service provider. Be careful, the cloud is a good thing, but not every merchant offers a cloud!

Then the editor will recommend one to you, the multiple backups mentioned above. No matter in terms of cost, safety or timeliness, a product can reach a high level. The editor has already tried it out before recommending it to everyone, and there is no pressure for me to use a low level of IT. I believe it is more convenient for you who have a foundation. Multiple backups support not only database backup, but also file backup and local data backup. So it can be said that as long as you need more backup can satisfy you. And the data is compressed and encrypted in the backup process, and uses the AES256 bit bank-level encryption standard, all encryption operations are completed independently on your device, which can be described as end-to-end encryption. After encryption, the multi-backup platform service generates redundant and mutually validated blocks of data, which are scattered and stored on hundreds of cloud nodes around the world. So unless the cloud center halfway around the world is paralyzed at the same time, data cannot be lost. At first, the cost of such a high-end product must be very high, but it is not. More than one backup every month will give away a certain amount of traffic space, when used up, you can do tasks in exchange for points and in exchange for some functions. Or through recharge in exchange for traffic, in the charge is also very user-friendly (1 yuan = 1G).
