The Data Protection Challenge
Rapid proliferation in social, mobile, cloud, and Internet of Things is driving enterprises to deploy hyperscale, distributed, data-centric applications such as customer analytics, e-commerce, security, surveillance, and business intelligence. To handle the data requirements of these high-volume, high–ingestion rate, and real-time applications, enterprises are rapidly adopting massively scalable and nonrelational databases such as DataStax Enterprise (DSE) or Apache Cassandra.
Like any business-critical application, these databases require data protection, including application-consistent backup; near-zero RPO and RTO; granular, repair-free recovery; failure handling; and backup storage efficiency. However, given the hyperscale, distributed nature of these databases, traditional backup and recovery products don’t support these requirements, leaving a critical data protection gap.
The Solution: Application-Centric Data Protection from Datos IO RecoverX
NetApp and Datos IO have partnered to extend the NetApp Data Fabric by providing application-centric data protection for next-generation applications. Enterprises can now leverage the performance, reliability, and flexibility of ONTAP 9 with the continuous data protection capability of Datos IO RecoverX. With this solution, enterprises can scale business-critical applications on a Cassandra database and be confident in the recoverability of data and the ability to maintain high application uptime. RecoverX is an industry-first scale-out, software-only data protection solution that is purpose-built for next-generation applications that are deployed on DSE or the Apache Cassandra database.
Datos IO RecoverX is founded upon Consistent Orchestrated Distributed Recovery (CODR), Datos IO’s cloud-first, scale-out data management architecture that enables customers to harness the cloud for both next-generation data protection and management. CODR uses elastic compute services that can be autoscaled with load and removes the dependency on media servers. CODR also transfers data in parallel to and from file-based and object-based secondary storage for multiple workloads, including data protection and testing and development. CODR offers:
- High availability. Deploying RecoverX in a cluster (three-node) configuration prevents any software process or external hardware (node) failures from compromising backup and recovery operations.
- Enhanced backup performance. With the scale-out architecture of DSE or the Apache Cassandra database, users can easily scale their database according to application growth. Similarly, the scale-out capability of RecoverX with no reliance on media servers helps customers increase backup and recovery throughput, leading to lower RPO.
By using native application intelligence, RecoverX creates an application-consistent point-in-time backup of the Apache Cassandra database at user-specified intervals, a concept that we call cluster-consistent versioning. A cluster-consistent version contains all the records that have achieved user-specified consistency. As a result, no repairs are needed when a version is restored back to the cluster, thus minimizing RTO. The backup operation is also highly parallel in its nature; RecoverX acts only as a control plane that orchestrates data movement from the data source cluster to version (secondary) storage. This approach allows RecoverX to handle large Cassandra databases and application workloads.
By allowing administrators to generate database backups at any user-specified time interval and at any granularity (table-level or entire database), RecoverX also simplifies operational use. Overall, versioning helps reduce data loss risk and minimizes capital and operating expenditures for an enterprise.
Fully orchestrated and granular recovery
Datos IO RecoverX provides single-click, fully orchestrated, any-point-in-time recovery. With RecoverX, customers can recover data directly back into the same database cluster (operational recovery) or to a different cluster (testing-anddevelopment refresh) with a different topology (number of database nodes). This option reduces the operational burden of refreshing testing and development clusters for continuous development DevOps environments. Further, the recovery process deals only with the logical data, making it three times faster than with traditional approaches. During recovery, the data is directly (with no reliance on media servers) transferred from secondary storage into target databases, resulting in a very low RTO.
Industry-first semantic deduplication
Semantic deduplication is an industry-first capability that Datos IO has developed to reduce the cost of storing backups of nonrelational databases over their retention period. Most nonrelational databases keep multiple copies of the primary data, called replicas. As part of versioning, Datos IO RecoverX deduplicates all the replicas of a primary dataset, thus greatly increasing storage savings without losing native formats. For example, if the database uses a replication factor of 3 (RF = 3), RecoverX saves up to about 70% in secondary storage costs. And by using its application awareness, RecoverX optimizes the backup of compacted SSTables, resulting in significant additional secondary storage savings.
Why NetApp plus Datos IO
NetApp big data solutions deliver an open, scalable storage system for building big data applications. Customers gain business insights—and value—more quickly. The NetApp All Flash FAS system offers predictable and high performance with consistent and low latency, resulting in a very fast response time to the most demanding applications that are deployed on Cassandra. And to deliver maximum uptime and high availability, it also offers nondisruptive operations and integrated data protection across applications, virtual infrastructures, and cloud architectures. Together with Datos IO, NetApp offers an industry-leading enterprise data management solution for Apache Cassandra that is based on ONTAP 9 and RecoverX.
Datos IO RecoverX is a software-only data protection product that can be deployed on a physical server, a virtual machine, or any cloud compute instance (for example, Amazon EC2). It communicates with the Apache Cassandra database through a Secure Shell (SSH) connection that forms a control plane to orchestrate data movement. The data can be backed up to a secondary FAS array or to a NetApp E-Series system. In addition to CLIs and RESTful APIs, customers can use the RecoverX consumer-grade UI to manage their data protection environment.
