We all know that cloud server can get the better security and performance. There are several VPS cloud backup disadvantages and advantages.
Cloud backup advantage
Efficiency and reliability: Cloud hosting providers utilize state-of-the-art technology, such as disk-based backup, application-specific protection, encryption, data deduplication, compression, server virtualization, storage virtualization and more in SAS 70-certified data centers. In addition to the security which accompanies their certification, many providers offer 24/7 monitoring, and reporting – capabilities, management and features which may not be afforded by other enterprises otherwise. Furthermore, there is no need to worry about migrations, upgrades or technology obsolescence; the burden of the backup infrastructure lies with the providers.
Accessibility: VPS cloud free backup may be attractive to organizations that could not afford the maintenance and investment of a disaster recovery infrastructure — or for those who can, but recognize the greater efficiency and cost savings to be got by outsourcing. Offsite data copies from any Internet – connected device — provide an added measure of guarantee in the event of a regional disaster.
Scalability with capital savings: Organizations can leverage the unlimited scalability of a third-party cloud company without the upfront capital expenditure. In fact, the pay-as-you-use model reduces significantly the procurement and provisioning headaches for backup. This approach allows for predictable management of capacity increase and operational costs.
Improve recovery time for small data sets: For a data recovery from tape, an operator would have to recall the tape and locate the data and recover the data. Conversely, file recovery from cloud storage is faster; it does not require physical transport from the offsite location, tape handling or seek time. Files to be recovered will be located and streamed over the WAN connection, saving time and eliminating the need for a local tape infrastructure.
Cloud backup disadvantages
There are cloud backup tradeoffs, too, including:
Nonexistent service-level agreements (SLAs): The performance of the service and the guarantees that ‘backup is successfully completed’ is not always in the service provider’s control. For example, availability of sufficient bandwidth, the amount of data which has to be transferred over the accessibilities and networks to systems is all scenarios which could contribute to non-compliance with service-level agreements.
Size limitations: Depending on bandwidth, each organization will have a threshold for the most suitable capacity of data that can be transferred daily to the VPS cloud Vietnam. These limitations will have an impact on backup strategies.
Seeding data and full recovery: Depending on the capacity of data, the first full backup and full recovery of website data could prove to be too time-consuming and impactful on production systems.
Service discontinuation: Understanding the most graceful “exit strategy” for the service is just as necessary as vetting specific features. Termination or early-withdrawal fees, and data extraction are a few of the factors to be considered.
