DRaaS: Disaster Recovery as a Service
In today’s world CEO’s, CIO’s ,SMB Business Owners etc need to know what to do if disaster strikes. A "disaster" refers to a complete halt of most or all of your systems simultaneously. If someone asks what your organization would do if all its systems went dark one fine day, and you can't answer that question with confidence, then you're setting yourself up for serious problems down the road—and that's "when," not "if.” As the saying going It’s better to be safe than sorry. Fortunately, the cloud and the internet combine to make recovering from system disasters easier and more accessible than ever. You may look at setting up a traditional DR site or you could explore DRAAS as a option, however it is of utmost importance to start working on a robust and comprehensive disaster recovery plan.
Kayimpex will help plan and implement a comprehensive and proactive Disaster Recovery plan that fits your business needs.
DRaaS v/s Traditional DR
Traditionally, disaster recovery and business continuity involved replicating data and applications on-premise. However, Cloud technologies have enabled DR solutions to be provided as a service, which offers a compelling alternative to the traditional methods. This leaves IT decision makers with an important choice; do you create an in house solution or move to a DRaaS solution? We will take you through the pros’s and cons of both the options
We can help you to understand the costs and drivers of Cloud computing and create a Cloud strategy tha business needs.
Traditional Disaster Recovery
Traditional DR involved using tape drives, CD or DVD backup's to duplicate data or replicating the production environment to an onsite DR hub. SMB's usually made frequent backups and stored the backup tapes offsite while Enterprise DR followed the same rules, but added provisioning for a DR-site, meaning another office that could be provisioned to house the data center infrastructure and workers on short notice, or at the very least, have spare hardware and infrastructure capacity on hand to quickly replace failed systems. These measure while ensuring some level of disaster-proofing are both slow by today's standards and exceedingly expensive, which is why many SMBs opt to ignore DR entirely. Costs are high due to investment in equipment along with the operational costs of hiring staff to maintain the backups. Efficiency is also compromised as restoring data from backup devices can be slow and error prone, which increases RTOs and RPOs. However, by using this traditional approach, companies may feel more assured about the location and ownership of their data.
Disaster Recovery as a Service - DRaas
DRaaS is a cloud based offering which replicates and hosts business critical data to virtual machines. A specialised third party vendor manages your snapshots and stores this information on a cloud, which can be restored back on to your machine in the event of a disaster.
This service based model offers a number of advantages over the traditional model. DRaaS offers substantial cost saving as organisations do not have to invest in the infrastructure required to carry out their own backup. Varied pricing models available significantly lower the costs, especially for smaller enterprises. Cloud sites are also automated, which reduces workload on internal staff, allowing them to concentrate on other projects. Cloud sites can also be made live within seconds or minutes, minimising data loss and reducing RTOs and RPOs. Geographic separation between the organisation and its remote backup site is also beneficial, as this enhances resilience.
However, one understandable concern for businesses is the security and privacy of their data, when held on a third party cloud. Whilst allowing a third party access to you data is always a risk, Kayimpex recommend a number of actions to mitigate this risk. Please contact us for further details.
Disaster recovery tailored to your business
Whatever your needs, our recovery experts will work with you to ensure that your custom plan is ready and locked in place should you need it.
Hot Site solutions provide immediate recovery of infrastructure, data and applications through a fully redundant, data center configuration that mirrors your systems. A hot backup site houses a duplicate of the data on your production server. This can be a real-time, mirror image of your data if that level of synchronization is set up. Dedicated data center space and infrastructure are included to ensure mission-critical applications are available in the event of a disaster.
This solution supports uninterruptible and near immediate recovery and are the preferred approach for organizations that perform real-time processes, including e-commerce companies, financial institutions, etc.
Warm Site solutions provide near-time recovery of infrastructure, data and applications through a redundant, data center configuration. The systems and data are synchronized on a periodic basis thus a warm site may have copies of your data on hand. However, those copies may not be complete or current. In other words, the data is not mirroring what is on your production server. A warm site allows you to resume operations more quickly than a cold site. But, there will still be a delay as full data backups are received from a remote backup site and put into place.
This solution is suitable for businesses that can tolerate several hours of downtime while systems are updated.
Cold Site solutions provide recovery of infrastructure, data and applications through configuration of equipment and restoration of data from backups at a disaster recovery location. This solution does not include mirroring of systems or data prior to disaster it is essentially just a space in a building that is properly configured to accept the equipment you will need to resume operations. This solution is suitable for non-mission critical applications and for businesses that do not need 24/7 availability.
There is significant work in getting this site up and running again. However, this is the least expensive type of backup site.
