BaaS vs. DRaaS: What is the Difference?

Backup as a service (BaaS) and disaster recovery as a service (DRaaS) are two methods for which businesses enable third-party offsite data protection strategies. The phrase “as a service” indicates the third-party providing the infrastructure and support can allow recovery during a disaster. Benefits to utilizing BaaS or DRaaS range from eliminating tape backups for modern cloud storage to making it unnecessary to maintain additional facilities or costly colocation spaces for disaster recovery purposes. Customers also gain technical expertise and on-demand resources to assist during a crisis. Both serve a critical purpose, but what is the difference between them? Here, we look at Baas vs. DRaaS.

Backup as a Service

In earlier years, tape backups were the most popular option for “offsite backups.” However, magnetic tapes are not a suitable medium for quick recoveries or restores. They also take time to retrieve and are an expensive item that companies might use only once. Modern backup solutions back up data to disk and accomplish two goals: speed and writing and reading the data for fast backups and restores and recoveries. For products such as Veeam® Backup & Replication™, users can back up locally to disk and then copy the backup file to a cloud provider for offsite storage.

Backup admins can complete fast restores and recoveries on-premises as needed and restore from cloud backups should something happen to their local copies. This practice follows 3-2-1 rule guidelines for having three copies of data – a production copy, backup copy, and an offsite copy.

Backup as a service use cases include:

  •       Long-term retention of files, applications, and data
  •       Archived data
  •       Secure, offsite cloud-based storage

Disaster Recovery as a Service

While backup as a service is appropriate for offsite protection of files, applications, and data, it generally does not enable bringing the entire infrastructure environments back online in the case of a disaster. Disaster recovery as a service provides a comprehensive protection strategy, encapsulating everything the production workloads and users need to perform their duties.

DRaaS uses replication technology to keep more current copies of production systems in a separate location. Along with the systems to run workloads, disaster recovery must include network connectivity, application interconnectivity, user access, and all the components needed during standard production runtime.

Disaster recovery as a service benefits include:

  •       Short-term, production-ready copies for low RPO/RTO
  •       Reduced cost and complexity from in-house implementation
  •       Hardware agnostic recovery
  •       A “more complete” solution than BaaS alone

Summary

Getting backups offsite is critical, and there are many options. Modern, accepted solutions involve cloud data repositories or disaster recovery to the cloud. Users should understand SLAs and the level of expected service with these offerings:

  • Backup as a service is suitable for long-term retention, with the ability to recover items quickly from various restore points. 
  • Disaster recovery as a service allows businesses to resume operations during a disaster or proactively before a disaster.
