What Is Online Cloud Backup and Why Is It Important?

When attached to “backup,” both cloud and online, commonly refer to the same solution — a backup established, managed, and maintained through a web service hosting remote data management infrastructure. Cloud and online backup services offer organizations secure storage and file sharing solutions with encryption, versioning, change management, and more.

Online syncing services like Google Drive, OneDrive, and Dropbox are commonly mistaken for cloud backup services because of their ability to mirror data across connected devices. However, cloud and online backup services refer to the more direct and dedicated cloud servers hosting remote backups for business-level workloads. Conversely, The services mentioned above are more similar to a cloud-based file server.

Online and cloud backups provide organizations with additional security and redundancy beyond traditional backups.

Backups have long been critical to protecting network data for the worst-case scenario. Whether it’s a natural disaster, accidental deletion, or a cyberattack, backups ensure organizations can promptly access essential data and resume operations.

Fulfilling the 3-2-1 Backup Rule

Cloud backups also align with the IT management best practices by following the 3-2-1 Principle of Backups. This principle says organizations should have three copies of backup data in at least two different forms of storage and one off-site copy.

The introduction of online and cloud backups gives organizations another type of storage, making establishing an off-site copy more accessible than ever before.

On-Premises Backups vs Cloud Backups

On-Premises BackupsCloud Backups
On-premises or local backups are the tapes, disks, and flash drives holding redundant data for an organization. With physical access, administrators have more control over local backups, and system reloads are typically faster.Online and cloud backups are available via SaaS vendors hosting global data centers and remote servers for backing up client data. Though clients give up physical controls, cloud backups offer extensive remote access, scalability, and reduced overhead.

Cloud & Online Backup Features

  • End-to-end encryption and security and privacy controls
  • Scalable cloud storage capacity with options for upgrading
  • Efficient cost for maximum allowable data
  • Continuous availability and redundancy for failover
  • Speed of data transfers, uploading, and downloading
  • Versioning and deduplication for analyzing and migrating data
  • Support for network-attached storage (NAS) devices
  • Support for major operating systems (Windows, macOS, Linux, iOS, and Android)

How to Choose a Cloud Backup Service

As cloud backups are critical to modern IT infrastructure, choosing the ideal online backup service can mean continued security, privacy, and redundancy for organization data. 

As the cloud backup market evolves to meet growing demand from individual consumers, advanced features and server-specific capabilities can be less straightforward at first glance. Pricing and features vary across backup solutions, so consider how organization needs and budget align. The added time to confirm whether a solution offers adequate storage capacity, encryption standard, or integrations is worth it.
