What is cloud data backup service?

Cloud data backup service is otherwise known as online data backup. This is a unique strategy which ensures business critical data is archived safely in a designated location.

A copy of such data can be sent out to a public or exclusive network located in an off-site server. This kind of a server is generally hosted by a third-party service provider. It bills the customer as per the capacity utilised, bandwidth consumed or number of users involved. Within such an enterprise, several off-site servers are considered to be proprietary. But such a charge back method is no different.

For the records, online data backup systems are characteristically built within a client software application running as per a predefined timeline, the schedule is determined by SLA or service level agreement purchased by the customer. In case a customer does not indenture daily backups, in that case the application would collect, compress, encrypt and/or transfer data to the designated service provider's server once in a day.

This process diminishes the amount of bandwidth which is utilised as well as time taken to carry out file transfers. Some service providers might as well render incremental backups which are restored only after carrying out an initial/full backup.

Sometimes, a third-party cloud backup is established which gains instant reputation amongst individual users and SMEs. Such a service is generally convenient. Many a times the capital expenditure incurred is due to the additional hardware and they are unnecessary because backups are run automatically without any manual intercession.

The fact remains that traditional backup still scores higher than cloud as far as the storage of critical data is concerned. Therefore, enterprises are making use of cloud backup services to archive all types of non-critical data. Cloud back up comes with short recovery time objective (RTO). As a result, cloud hosting providers have joined hands to resolve the issue related to the physical limits as far as data movement to cloud is concerned.
