Cloud storage is a networked online storage model in which data is stored on multiple virtual servers, usually hosted by a third party, rather than on dedicated servers. Hosting companies operate large data centers, and those who require data storage hosting meet their data storage needs by purchasing or leasing storage space from them.
The data center operator prepares the storage virtualization resources on the back end according to the customer’s needs and provides them as a storage pool, which the customer can use to store data or files. In fact, these resources may be distributed across numerous server hosts.
The cloud storage service is accessed through a Web service application programming interface (API), or through a Web-based user interface.
- Advantages of cloud storage.
- Users only pay for the storage capacity they actually use.
- Users do not need to install physical storage in their own data center or office environment, which reduces IT and hosting costs.
- Storage maintenance tasks (such as backups, data replication and procurement of additional storage) are shifted to the service provider, allowing enterprise organizations to focus on their core business.
Potential problems with cloud storage.
- Data security becomes a potential concern when sensitive data is stored with a cloud storage provider.
- Performance may be lower than local storage.
- Reliability and availability depend on the availability of the WAN and the level of precautions taken by the service provider.
- Users with specific record retention needs, such as public agencies that must retain electronic records, may encounter some complications in adopting cloud computing and cloud storage.
The current cloud storage is mainly divided into public cloud, private cloud, and hybrid cloud. Public clouds usually refer to clouds that can be used by third-party providers for users, and public clouds are generally available over the Internet.
Private clouds are built for the sole use of one customer, and thus provide the most effective control over data, security, and quality of service.
Private clouds can be deployed within the firewall of an enterprise data center or they can be deployed in a secure colocation site, with the core attribute of a private cloud being proprietary resources.
Private clouds can be provided by the enterprise or erected by itself. A public cloud blends public and private clouds. The security of the private cloud is beyond that of the public cloud, while the computing resources of the public cloud are beyond the reach of the private cloud.
In this spear and shield situation, the hybrid cloud perfectly solves this problem, it can use the security of the private cloud to keep the important internal data in the local data center; at the same time, it can also use the computing resources of public cloud to complete the work more efficiently and quickly, compared to a private cloud or public cloud are more perfect.
Although it is possible to provide data to multiple people at once, or to transfer data to people in different locations, when a single person transfers data (e.g., files from a cell phone to a computer, or from a computer to a cell phone), it is not as fast as using a transfer line because it requires a new “upload” and “download”. It is not as fast as using a transmission line because it is like taking a long way around.
In the case of transferring large data, if the Internet is disconnected or the cloud service provider makes a mistake, it may be necessary to re-transfer a small amount of data, or a large amount of data may be lost.
How to use cloud storage safely? First of all, do not put important data or data related to personal privacy on the cloud server, after all, there is no absolutely safe cloud storage. Secondly, important data should be well backed up locally to prevent cloud service interruption or cloud data loss, and other unexpected situations.
Then again, when choosing a public cloud, choose some global or more well-known service providers, after all, these service providers have technical strength in data encryption transmission and encryption storage.
Then it is necessary to set a higher strength password and turn off the automatic login option, before replacing or discarding the mobile device to empty the device to save the cloud service login password, to ensure that their own data is not leaked.
How to ensure cloud storage security?
Vinchin Backup & Recovery allows you to recover the entire VM and all its data from any restore point (full backup, incremental backup, or differential backup) without affecting the original backup data. Backups that have been deduplicated or compressed can be recovered. It is an excellent solution for ensuring enterprise business continuity and minimizing critical business interruptions caused by disaster or system failure.
You can also quickly validate backup data availability by instantly restoring the target VM to a remote location in a matter of minutes.
Ascertain that, in the event of a true disaster, all VMs can be recovered and that the data contained within is not lost or damaged. Minchin provides solutions such as VMware backup for the world’s most popular virtual environments, XenServer backup, XCP-ng backup, Hyper-V backup, RHV/oVirt backup, etc.
