Data protection in hybrid cloud environments

The cloud has changed the way organizations store and manage their data and applications. While local backups still play an important role in preventing data loss due to hardware failure and human error, they cannot meet all data recovery and availability requirements in an increasingly decentralized, hybrid and cloud-based environment. Enterprises therefore need to develop a differentiated backup strategy that incorporates various backup and recovery methods, such as cloud backups, hybrid backups and disaster recovery plans, and is tailored to their specific data and platform requirements.

Hybrid cloud has become a popular option for organizations that need to manage highly sensitive data. It offers the benefits of the cloud, such as flexibility, scalability and managed services, but also the ability to store and process sensitive data locally. The on-premises component can provide a higher level of control and security required for specific data and applications. By combining the two approaches, enterprises can create a hybrid infrastructure that meets their specific needs while providing a flexible and scalable solution.

The cloud and the limits of data resilience

One of the most common methods cloud providers offer to optimize data resilience is replication. This involves copying data from one location to another to ensure it remains available in the event of a failure of the primary location. There are different types of replication, such as synchronous replication, where data is copied immediately to a secondary location, or asynchronous replication, where data is copied with a delay. Choosing the right replication method depends on several factors, such as the type of application, RPO (Recovery Point Objective) and RTO (Recovery Time Objective) requirements, and cost.

  • Replication across data stores. It's easy to enable data replication and mirror your data from one location to another (or several others).

  • Replication across cloud regions. Another common resilience strategy is to mirror or replicate data to completely different geographic regions. If a disaster were to destroy data storage in one of your locations, your data would be reliably protected in another.

  • Replication from local storage to the cloud (or vice versa). A variation on regional replication is using a cloud to replicate data from local storage - or from the cloud to local data stores. With this approach, many users feel more secure because critical data resides in an on-premises, company-owned facility.

While resilience strategies such as replication are important measures to ensure data availability in the event of failures, there are some problems they cannot solve. Some of these problems are:

  1. Data loss due to human error, malware, or other cyberattacks that may cause data encryption or data corruption.

  2. Data breaches where data is stolen or exposed.

  3. Permanent outages that may be caused by natural disasters or other unforeseen events.

To address these issues, organizations need a comprehensive

data protection strategy that includes a combination of resilience, data protection, disaster recovery and recovery measures.

Data backup and management

Data backup and data resilience are two different concepts, both of which are important for preventing data loss and ensuring high availability of data.

Data backup refers to the process of creating and retaining copies of data so that it can be restored in the event of data loss. In this process, data is often backed up to separate media that are separate from the primary storage media. This ensures that in the event of failure or corruption of the primary storage media, a copy of the data is available to be recovered.

Data resilience, on the other hand, refers to the ability of systems and infrastructures to withstand failures or disruptions and maintain data availability. Measures such as replication, failover or load balancing are often used to ensure that data still remains available in the event of a failure.

Both concepts complement each other, as a successful data protection strategy helps to increase data resilience and vice versa.

A unified, centralized data protection solution is an effective way to manage and protect data in a hybrid cloud. Unity should exist in several respects:

  1. Unified data protection: The solution should be able to protect all types of data and workloads present in the hybrid cloud environment. This includes, for example, data in virtualized environments, on physical servers, in cloud platforms and in SaaS applications.

  2. Unified management: The solution should allow all data backup and recovery activities to be managed centrally. This can simplify the management of the hybrid cloud environment.

  3. Unified reporting: The solution should be able to generate reports on all backup and recovery activities in the hybrid cloud environment. This enables monitoring of key metrics such as data recovery status or SLA compliance.

  4. Unified security: The solution should have built-in security features to protect the data in the hybrid cloud environment. This includes, for example, encryption, authentication and access control.

  5. Eine einheitliche, zentrale Datensicherungslösung kann Unternehmen dabei helfen, ihre Daten effektiv zu schützen und zu verwalten, unabhängig davon, wo sich diese Daten befinden oder wie sie verarbeitet werden.

Data protection in a hybrid cloud environment is a complex task that requires specialized knowledge and skills. It is important to have an experienced vendor and partner that can assist with disaster recovery and data restoration.

A good vendor should be able to develop a comprehensive data protection strategy tailored to the specific needs of the organization. The strategy should include a combination of technologies and processes to ensure that data can be reliably backed up and recovered in the hybrid cloud environment.

In addition, the provider should have extensive experience in disaster recovery and data restoration. In the event of a failure or disruption in the hybrid cloud environment, the provider should be able to respond quickly and effectively to support data recovery.

An experienced provider and partner can thus help companies securely and reliably back up and recover their data in the hybrid cloud environment.
