Understanding the key differences between BaaS and DRaaS

There are a number of differences between BaaS and DRaaS. BaaS or Backup as a Service means that your data is backed up online by an external service provider to an off-site storage system. You decide what files should be backed up eg application development, databases, images, source code and/or other data files. The service provider is available on demand to restore such data as deemed required by the customer, should a problem occur such as corruption or accidental deletion.

However, it is the customer’s responsibility to have a suitable platform available so that if a major problem occurs, such as fire, flood or breach, you may have to install and configure the required hardware. And this takes time – from 24 to 48 hours. Once this is done, your Backup as a Service provider restores the data and your business is back up and running.

But it also backs up your services and applications – not just your data. This means that should a disaster occur, such as a cyber-attack or even a power cut, your data and critical infrastructure are restored within a previously agreed timeframe. This is usually between one and four hours.

With BaaS, your service provider manages, tests and maintains your data backups and your provider also restores it – but it is only the data that the provider is responsible for restoring.

DRaaS involves assessing and evaluating the business risk. With DRaaS, company servers are replicated either to a secondary site (if the company has one) or increasingly, off-site to the cloud. The replication level and timeframe is agreed during the consultation and the solution is customised to meet that timeframe. It could be a minimum, scaled-down running environment or a full copy of the entire infrastructure in the cloud.

If a disaster strikes, the DRaaS provider restores the infrastructure as agreed in the Service Level Agreement. This includes file systems, hosted applications and current system configurations. Your DRaaS provider deploys the disaster recovery servers and provides the staff and applications with remote access. So, the only thing you have to worry about is turning on the replicated servers and getting back to work.

With all these differences between BaaS and DRaas, how do you choose?

Choose BaaS if…

  • You can easily reassemble your infrastructure in case of disaster
  • Access to data is not required frequently
  • Your RPO and RTO are acceptable
  • You have a disaster recovery specialist in house
  • You need a cost effective solution

Choose DRaaS if…

  • Your IT infrastructure can’t be easily and quickly rebuilt
  • You use web-services or applications that require 24/7 access by staff and/or customers
  • Your data requirements are increasing dramatically
  • You’ve calculated that the additional expense is worth the potential losses with downtime
