What is cloud backup and how does it work?

 

Cloud backup is another name for online backup or remote backup. Service is a measure that helps prevent equipment failure.

In case of equipment failure, Cloud Backup sends a copy of the virtual or physical file to a separate database. This database is located on an offsite location, and the data is properly stored. For a large number of companies, cloud backups come as a complementary form of backup.

It is a third-party service provider that typically hosts storage systems and secondary servers alike. Fees are charged from the backup customer. Fees are often subject to criteria such as the number of servers or how often the data is evaluated. Similarly, it may be subject to capacity used, storage space, number of users or data transmission bandwidth.

The importance of cloud data backup

With the implementation of cloud data backup, the organization’s data security strategy becomes stronger. This also happens when the workload on IT staff does not increase.

As the strategy saves man-hours, they often cover up the various additional costs associated with cloud data backup. These costs include data transmission charges.

Definition of cloud

Cloud computing is a service hosted on the Internet. Unlike web hosting, the services provided on the cloud are sold on demand. This allows the customer to use the service more or less as required. The service provider manages the services extensively.

Public cloud

The public cloud sells services to anyone who may be present on the Internet. An example is Amazon Web Service (AWS).

Private cloud

Private Cloud provides hosted services to a limited number of users.

How does cloud backup work?

Off-site backups typically come in a number of formats. Cloud backups are the most popular among them.

The data is copied first. The backup application then stores data on various media. This takes place in the organization’s data center.

Essential steps associated with cloud backup:

  • Files for backup have been assigned. They are mostly those who have new or updated data.
  • The backed up files are encrypted.
  • They are sent off-site to the cloud.
  • Public cloud, private cloud or cloud-to-cloud (C2C) backup methods are available.
  • Files are easily accessible. In the event of a recovery, they are readily available.

Cloud backups typically have different approaches. They are selected based on their potential to fit into the organization’s current data protection processes.

Let’s take a look at the different approaches associated with cloud backup:

Backing up directly to the cloud

Copying resources in the public cloud is one way to store organizational supplies. Data is written directly to cloud providers, such as Microsoft Azure or Amazon Web Services (AWS).

To copy the data, the organization uses its own backup software. Retrieves data after cloud storage service.

Backup software must be able to interface with cloud storage. Cloud storage does not provide backup software in this case.

Backing up to a cloud service provider

Backup services are provided in a managed data center. The backup software is part of the service or the service supports the backup application.

Cloud-to-Cloud (C2C) Backup

C2C backup services are relatively new. They copy data from the cloud to the cloud and host software to handle the processes. The data is already in the cloud. Alternatively the software hosts data as a service (SAS).

Online cloud backup systems

They are hardware options for backing up data in a cloud backup service. Backup machines include backup software, disk capacity, and a backup server as an all-in-one service. Some vendors offering such services are Dell EMC, Unitrends and Quantum.
