Disaster Recovery as a Service
It’s becoming more common for businesses to utilize the cloud – from start up to the largest enterprises. With this comes challenges around disaster recovery of mission critical services. In this article we’re going to cover a bit about Disaster Recovery as a Service, DRaaS for short.
Firstly, what is Disaster Recovery as a Service?
Disaster Recovery as a Service is basically replicating and hosting either physical or virtual machines; typically through a third party provider (such as Test My Backups). Its main aim is to provide a quick fail-over to minimize downtime in the situation where an IT event occurs (such as a natural disaster like a flood has engulfed the businesses headquarters).
Advantages of Disaster Recovery as a Service
Immediate restoration of critical services – There isn’t any need to copy data back from the Internet which is the main time intensive task in a restoration scenario. DRaaS allows for immediate failover when a system or site becomes unavailable.
Professional expertise – By outsourcing to a DRaaS provider; you’re allowing qualified experts to implement a full disaster recovery plan so your focus can be on your core business. They’ll also be able to perform effective disaster recovery testing.
Low overheads – The standard DRaaS provider will charge one of two ways:
No matter which option, it’s more financially viable for SMB or SME to outsource their disaster recovery for a monthly or usage fee. This is instead of paying for the upfront purchase costs of hardware, then pay for ongoing maintenance and management with an internal IT team.
Challenges of Disaster Recovery as a Service
Trusting an external entity – Your data will be stored by the DRaaS provider where they’ll be in full control. Your business will be in their hands should a major incident occur – it’s a large leap for some business owners.
Performance Issues – If your applications are usually run on premise; then it’s likely that there will be a noticed effect on speeds when running them from the DR site over the Internet. However it’s better than not running at all.
