Cloud vs. On-Prem Backup: What’s the Difference and Which is More Secure?

Data backup is one of the most important tasks for any company, as data loss can have serious consequences. To prevent this, companies typically rely on backup solutions. But which backup solution is the best? A backup in the cloud or on-premises (locally within the company)? Which is more secure? What distinguishes the two?

What is Cloud Backup?

Cloud backup refers to storing data in a remote data center managed by a cloud service provider. A typical example is OneDrive.

Advantages of Cloud Backup:

• Automatic backups: Backups can be created regularly without manual effort. A structured backup strategy is crucial here – hosttech provides 7 helpful data backup tips, especially for businesses.
• Scalability: Storage space can be flexibly adjusted according to needs.
• Geo-redundancy: Data is often backed up across multiple data centers, providing protection against local disasters or failures.
• No own hardware required: You save costs for servers, maintenance, and energy.

Disadvantages of Cloud Backup:

• Provider dependency: Long-term costs and availability depend on the provider's pricing and stability.
• Internet dependency: Without a stable internet connection, accessing data can be difficult.
• Security risks through third-party providers: Data could potentially be targeted by hacker attacks or data breaches.

What is On-Prem Backup?

On-premises backup refers to storing data on company-owned hardware, such as local servers or NAS (Network Attached Storage).

Advantages of On-Prem Backup:

• Full data control: No dependency on external service providers.
• Faster recovery: Since data is stored locally, it can often be restored faster than from the cloud.
• Better data protection control: Sensitive data remains within your own IT environment and isn't subject to external access.

Disadvantages of On-Prem Backup:

• High initial investments: Hardware, maintenance, and IT staff cause higher costs.
• Limited scalability: Storage space is limited and requires manual expansions.
• Risk from local disasters: Fire, flood, or hardware failures can lead to complete data loss if no external copy exists.

Which is More Secure? Cloud or On-Prem Backup?

Whether cloud or on-prem backup is the better choice depends on your individual requirements. Cloud backups offer greater flexibility and better redundancy, while on-prem backups provide more control and faster recovery. A hybrid strategy that combines both approaches is the best solution to ensure maximum security and availability. Ultimately, you should choose a backup strategy that is both economically and technically optimal for your needs.
