Advantages 1. Highly effective 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 more. In addition to the security requirements of the certification requirements, most providers also provide 7x24 monitoring, management, and reporting. These capabilities may not be affordable to the average company.
2, reduce the recovery time of small amount of data
When recovering from tape, the administrator needs to find the tape, load it, find the location of the data, and recover the data. The recovery of data from the cloud is much faster; it does not require the delivery of tapes from the tape storage site, disposal and search time. The data that needs to be recovered is transmitted over the wide area network (WAN), saving time and eliminating the need for a local tape device.
3, availability
Companies that cannot afford a disaster recovery architecture can afford it, but realizing that outsourcing can increase efficiency and reduce costs, cloud backups can be attractive. Outbound data copies can be accessed through any Internet connection or device, increasing the insurance factor in the event of a regional disaster.
Cloud backup: not without flaws!
1, backup data and fully recover
Depending on the size of the entire data, the first full backup and complete data recovery may be too time-consuming and have a large impact on the production system.
2, size restrictions
Based on existing bandwidth resources, each company will have a reasonable threshold for the amount of data that can be transmitted to the cloud each day. This restriction will have an impact on the backup strategy.
3, termination of service
Understanding the best "introduction strategy" is as important as reviewing specific features. Indicators to consider include service termination fees, early exit fees, cancellation notices, data retrieval methods, and more.
4. Non-existent service level agreements
The performance of the service and the "guarantee" that the backup can be successfully completed are often not what the service provider can control. For example, whether there is enough bandwidth, the amount of data that needs to be transmitted over the network, or the accessibility of the protected system may result in failure to comply with service level agreements.
Cloud backup: Are you suitable?
As a storage manager, you should correctly evaluate the challenges the company is facing, its capabilities, and the assets it owns, which will help you determine whether your cloud-based backup strategy is better than continuing to rely on full indoor backup. The following are some aspects to consider:
1, budget
For indoor backup and cloud backup, you may wish to make a comparison: For tape backup strategy, there are maintenance costs for indoor hardware and software, media purchase fees and storage fees; for hybrid cloud services, you have to spend three years Operating expenses.
2, daily need to backup data capacity
How much data need to be protected (based on the total data capacity and daily data rate of change)? In order to meet recovery goals, what backup frequency do you need? Calculate how much data you need to transmit on the daily amount of data and whether these transfers can be done within the backup window under existing bandwidth conditions.
3, blank areas for data protection
Do you have new instructions to improve data protection in ROBO or other terminals? Do you have employees and capital budgets to invest in these new actions? Do you currently have a disaster recovery (DR) strategy? If so, are your people, processes, and technologies allowed to meet RTOs and RPOs? Using a cloud backup vendor to expand existing in-premises data protection (without requiring advance payments to facilities and without additional personnel) may result in more cost savings than the expansion of existing on-premises equipment.
　　 4. Does the current system architecture of the system architecture limit the satisfaction of the organization's needs? Has the budget shortage kept you from keeping up with technological advances? Are you going to make technical updates anytime soon?
5. Service Level Agreements (SLAs) and Legal Compliance Needs
Can you complete data backup within the prescribed window time? Are you completing the data recovery within the time limit of the internal agreement? If not, is it because the technology is outdated or because there is not enough operational staff? Can you meet the regulatory requirements of companies and regulations with existing personnel, processes, and technologies? Do you maintain the copy outside the device to introduce possible security risks? If your data recovery service level agreements (SLAs) are more stringent than streaming media data transfer over WAN links or physical removable disks, cloud-based backup may not be for you. If you do not have the discipline and ability to meet legal compliance goals, outsourcing data protection to a company that supports legal compliance is feasible.
6, staff level and professionalism
Does the current economic environment affect your staffing for data protection? Is your current backup/restore architecture too dependent on the employees who work for it? Do you have internal experts to properly construct and maintain data protection architectures and procedures to meet your current and future goals? Operators are often the most costly aspect of data protection, so introducing data protection capabilities that do not require additional personnel may be more feasible.
With a clear understanding of cloud backups and business status, the next step can be to determine the implementation of cloud backup. However, remember that you must choose a reliable cloud service provider and sign a clear cooperation agreement. Be careful, cloud is a good thing, but not every merchant offers cloud!
Analysis of the advantages and disadvantages of cloud storage backup data protection
After using the cloud storage backup, the industry can rely on the unlimited expansion capabilities of third-party cloud providers without worrying about investment issues. In fact, using pay-as-you-go models reduces the headaches of backup purchases and implementation. This approach allows us to predict and manage capacity growth and operating expenses.
