Cloud Backup and Recovery

Cloud Backup and Recovery

When it comes to safeguarding sensitive data, such as credit card and login information, most organizations rely on remote data centers that house numerous servers for storage. Typically, these data centers face vulnerabilities to natural disasters like tornadoes and hurricanes.

Furthermore, cybercriminals can exploit these remote data centers, compromising critical customer data. In such cases, your company may be held accountable for the resulting damage. To ensure the perpetual security and accessibility of sensitive data, the implementation of cloud backup is paramount.

Exploring the “Cloud”

The term “cloud” denotes the delivery of computing resources, such as storage and applications, over the Internet. It comprises numerous servers scattered worldwide, owned and managed by cloud providers, who offer on-demand SaaS solutions to customers.

Storing data or applications in the cloud means relying on the cloud provider’s infrastructure, obviating the need for companies to purchase and maintain their hardware—a potentially costly endeavor. Three primary types of cloud storage exist:

1. Public Cloud Storage: The most common type, offered by providers like Amazon Web Services (AWS) and Microsoft Azure, is suitable for non-confidential data.
2. Private Cloud Storage: Employed by organizations seeking secure environments with access restricted to authorized users, provided by companies like Rackspace and IBM Bluemix.
3. Hybrid Cloud Storage: Combines public and private clouds, allowing secure storage of sensitive data while using the public cloud for less sensitive information.

Unveiling Cloud Backup

Cloud backup, also known as online or remote backup, involves the process of storing data on cloud-based servers. When data is backed up to the cloud, it’s duplicated on one or more remote servers managed by a third-party cloud service provider. Typically, these providers charge fees based on factors like storage space, server bandwidth, and user access.

How Cloud Backup Operates

It operates by replicating a company’s data on cloud-based servers. This can be achieved in two ways:

1. Continuous Replication: Data changes are immediately copied to cloud servers, ensuring an always up-to-date copy.
2. Scheduled Replication: Data is copied on a predefined schedule, suitable for scenarios where real-time updates are unnecessary.

Once data resides in the cloud, it becomes accessible worldwide via an internet connection.

Mitigating Cyberattacks with Cloud Backup

Cloud backup combats cyberattack through two mechanisms:

1. Data Redundancy: Cloud providers maintain multiple copies of your data on separate servers. If one server is compromised, you can still access data from another, thwarting potential loss.
2. Ransomware Recovery: In the event of ransomware attacks, where data is encrypted and held hostage, cloud backup facilitates swift recovery, negating the need to pay ransom.

Two Cloud Backup Approaches

Embarking on cloud backup is relatively straightforward, offering two primary methods:

1. Backup-as-a-Service (BaaS): Cloud providers manage your backups, requiring you to connect to their servers to initiate data backup.
2. Platform-as-a-Service (PaaS): Providers furnish a platform for storing and managing backups, granting more control over the process.

Benefits of Cloud Backup

Cloud backup offers numerous advantages, including:

1. Enhanced Availability: By replicating data on cloud servers, a copy is perpetually accessible, ensuring critical data availability during unexpected downtimes.
2. Cost Savings: Leveraging the cloud provider’s infrastructure minimizes IT expenses significantly.
3. Scalability: The cloud allows resource scaling, ideal for businesses experiencing periodic demand spikes.
4. Security: Cloud platforms provide multiple layers of security, crucial for safeguarding sensitive data.
5. Disaster Recovery: Cloud backup expedites data restoration during disasters, even preventing data loss.

Drawbacks of Cloud Backup

Despite its merits, cloud backup does have some downsides:

1. Data Latency: Cloud platforms may exhibit latency issues in specific global regions, impacting real-time data access.
2. Bandwidth Requirements: A high-speed internet connection is imperative for efficient cloud operation.
3. Data Sovereignty: Entrusting data to a cloud provider may pose issues for companies subject to data sovereignty laws.

Cloud Backup vs. Cloud Storage

Cloud storage and cloud backup are distinct concepts:

• Cloud Storage: It entails archiving data or freeing up local server space by storing data in the cloud.
• Cloud Backup: Involves replicating data to cloud-based storage, serving disaster recovery and off-site data copy purposes.

In essence, cloud backup offers a more comprehensive solution compared to cloud storage, serving both disaster recovery and archiving objectives.

Best Practices for Cloud Backup

Once you’ve chosen a cloud backup solution, these four tips will safeguard your data against unauthorized access and malicious threats:

1. 3-2-1 Rule: Maintain at least three data copies, two on different media, and one off-site.
2. Two-Factor Authentication: Employ an extra layer of security to protect data from unauthorized access.
3. Regular Backup Schedule: Back up data consistently to ensure up-to-date copies.
4. HIPAA Compliance: Choose a HIPAA-compliant cloud provider for handling Protected Health Information (PHI) to comply with federal regulations.

By adhering to these practices, your company can effectively preserve data integrity and security with cloud backup.
