What factors should I keep in mind when selecting a cloud backup service provider?

Take into account the following aspects while deciding on a Cloud Backup service provider:

1. Scope of Backup: Determine the extent of the backup service provided. Does it cover the infrastructure level only or does it extend to the application down to file level as well?
2. Data Restoration: Evaluate how easy it is to restore data. Can you restore data easily at the file level or at a more granular block level?
3. Pricing Structure: Understand the pricing model of the service. Are you charged per virtual machine (VM) agent or is there a different pricing structure in place?
4. Responsibilities as a Customer: Clarify your responsibilities as the recipient of the service. What tasks or actions are expected from you in the backup process?
5. Scalability and On-Demand Storage: Check if the backup and storage capabilities are flexible and on-demand. Can you easily scale up your storage capacity whenever needed?
