Need a backup in the cloud?

Why do you need a backup in the cloud? Here's why you need a backup.

Cloud backup is the replication and storage of data on a cloud server. Backing up customer data, sales data, etc. necessary for the continuation of a company is indispensable and natural.

Backups in the past have been laborious and time-consuming, but cloud backups are a convenient backup method.

Ransomware measures

Ransomware is a ransomware virus that locks your computer and encrypts files, and is not a countermeasure for network HDDs and external HDDs. If you install a cloud dedicated to backup that is not shared, it will not be encrypted because you do not have the authority to write files, which is effective as a countermeasure against ransomware.

Disaster countermeasures

The backup destination of the cloud differs depending on the cloud provider, but you can back up at multiple backup centers including overseas, or you can choose a backup center in a remote location. Many backup centers are robust backup centers equipped with private power generation, etc., so that they are highly redundant and can respond to disasters. In the unlikely event that your company suffers a disaster, important data remains, so early reconstruction is possible.

Operation cost reduction

If you back up in the cloud, you do not need to install and maintain your own server like on-premises. You can reduce the cost of the server and the cost of the operator. Even if your business is on track, scales up and the amount of data increases, you only need to increase capacity because of its high scalability. The cloud is a mechanism that pays only for the resources used.

Backup efficiency

With conventional backup, engineers and others had to stick to the work, and every time an error occurred, they had to deal with it. With cloud backup, you don't need to assign people because you will be notified by an alert. If you specify the date and time and range, it will be backed up automatically.

Expansion of backup target

With the introduction of telework, the scope of backup has expanded. Files on devices used for telework and files in cloud storage can also be backed up in the cloud. By expanding the target data for cloud backup, it will be possible to access from anywhere and it will also be possible to support telework.

Data backup and system backup are different

Backups include data backups and system backups. Here, we will explain about two backups.

System backup is a backup method that stores the same system on a backup server. The purpose of system backup is to recover system data. If the system and system data are set to synchronize, even if there is a problem with the system, it can be recovered immediately. If you back up the entire OS and applications, you can recover from the system data of the previous generation.

A data backup duplicates and stores only the data. Restoration is difficult if the data is completely erased due to a problem with the hard disk. It is necessary to take measures so that the loss of data does not hinder business operations.

Cloud backup type

There are three types of cloud backups. Here, we will explain each cloud backup.

The image backup type backs up a wide range of files, applications, operating systems, and other systems. Since user accounts and user settings are also backed up, even if there is a problem, everything can be restored.

An image of an image backup is a single piece of data for the entire system. Everything from the system to the files is backed up, so you don't have to install the app or set up an account from scratch when restoring.

Like data backup, file backup type is a type that backs up only specific files or data. You can back up even if the cloud capacity is small, and you can set it to back up automatically. It can be used to efficiently and automatically back up specific files.

File storage is a storage device that stores data in file units. File storage on the cloud also has a service that can be synchronized with a computer, so it can be used as a backup in case of emergency. Since some cloud storages themselves have a backup function, they are considered as one of the backup options.

Benefits of cloud backup

Cloud backup has many benefits. Here, we will introduce seven typical ones.

Cloud backup basically has no initial cost. You only need an internet environment and a device. In the case of your own server, you will be charged for the purchase of physical servers and apps, and the cost of acquiring licenses. Most clouds are pay-as-you-go, paying only for what you use. You only pay for the resources you use, so there are no extra costs.

Cloud backup also does not require management. Since there is no hardware such as a server, there is no need for an engineer to maintain and manage. Maintenance management is performed by the cloud provider. However, when you first introduce cloud backup, make sure that the backup is successful.

Image backup with cloud back is useful in case of emergency. Cloud providers own a number of data centers in completely remote locations, so even if their company suffers a disaster, the essential data remains. As long as the device and internet environment are in place, the system can be restored immediately, and it is possible to return to business using data.

Cloud backup stores secondary storage data on the cloud. Even if you accidentally erase the data, you can recover it early. If you are backing up on your own server or hard disk, you may not be able to recover the erased data.Synchronize your device with your cloud backup so you don't even have to manage generations

For cloud backup, you can set permissions for each file or folder. Since only specific users can access it, data leakage can be prevented and security can be improved. By setting the confidential information in the company so that only executives can access it, it is possible to improve the efficiency of information control in the company.

Cloud backup can leave log data of access and editing such as files. Since the time and person who accessed the file can be identified, problems such as information leakage and illegal data rewriting can be dealt with promptly. By informing employees that log data can be retained, fraud deterrence can also be obtained.

By introducing cloud backup, you can increase resources as the capacity of backup data increases. If the server is a hard disk, it must be added. With the cloud, you can increase or decrease resources with simple operations without increasing hardware, so you can use what you need, when you need it, and as much as you need.

Disadvantages of cloud backup

The disadvantages of cloud backup are basically small, but here are four typical ones. Since the disadvantages differ depending on the cloud provider, the disadvantages introduced here are not common to all cloud services.

Cloud backup is a mechanism for storing data on a virtual server in the cloud space provided by the operator. Some companies are worried about security because they use external servers. When introducing cloud backup, it is important to check the contents of the backup center and security such as data encryption, and eliminate security concerns.

Proper operation of cloud storage is an issue when performing cloud backup. If you do not use the high-performance duplicate deletion function, the capacity of cloud storage will increase and the cost will increase due to the pay-as-you-go system, so be careful. When implementing cloud backup to reduce costs, it is important to narrow down the backup target.

When transferring a large amount of backup data to a backup center in a remote location, there are concerns about bandwidth pressure. Bandwidth is the amount of data that can be sent on an hourly basis. Bandwidth pressure for your company's backups can be annoying to other users. You may be asked to take measures such as deduplication and adjusting the transfer rate.

Due to backup and synchronous backup, the operation of devices such as devices may become heavy, which may hinder business operations. We do not recommend a backup system that puts an excessive load on the hardware. Decreased operational efficiency and productivity can also be a factor in reducing employee motivation. Prior testing is required before deploying cloud backup.

summary

Backup is essential to keep your business running. With cloud backup, you can recover quickly even if your company has a disaster.

Systems that have a backup function in the file storage without introducing cloud backup are also attracting attention. Since the KDDI file storage service is equipped with a backup function (generation management function), there is no need to bother to install only cloud backup. You can check and share proposal materials, images, video files, etc. from various devices anytime, anywhere.
