Even before there were computers, backups for records were an important consideration for businesses. Many kept duplicate copies of key files in fire-proof safes or secondary locations. Now, with the rapid expansion of digital resources and business applications, managing backups has taken on a renewed centrality for disaster readiness. Whereas the tape-based backup systems of the early computer age could take a significant amount of time to update and restore, today’s leading solutions facilitate business continuity, not just disaster recovery.
Evolving DR processes
Thanks to technological advancement such as cloud services, organizations now have more diverse and advantageous DR and BC options. As CloudTweaks recently highlighted, many of the benefits that make the cloud an attractive choice for data management and application hosting in general qualify it as a prime DR/BC resource: It provides cost-effective solutions, rapid provisioning, scalability and elasticity. Consequently, cloud-based backups can easily adapt to changing business needs and enable entire servers to be protected by virtualization or other DR strategies.
Additionally, just as the hybrid cloud promises great flexibility for companies to create systems tailored to their unique needs, the leading DR offerings enable organizations to optimize their processes by better planning which resources are replicated and protected in which manner. This added customization helps businesses ensure that their mission-critical data and tools will be readily available even if they experience a disaster, all without straining their bandwidth or burning a hole in their pocketbooks.
Hot, warm or cold?
Because downtime and data loss can have devastating effects on organizations, it’s important not to be lukewarm or ambivalent about DR. However, when it comes to choosing the manner of protection, there are a few “temperatures” that decision-makers can choose from to meet their companies’ unique requirements.
Datapipe offers hot, warm and cold sites for DR plans. Each option has benefits that make it appropriate for particular types of resources:
- Hot sites facilitate continuous performance and almost immediate recovery by mirroring production environments in dedicated data centers. This is particularly appropriate for mission-critical applications and resources that businesses need to access without pause.
- Warm sites synchronize infrastructure, applications and data periodically and provide near-real time recovery. They are suitable for businesses and resources that can stand to wait for a few hours for systems to be fully updated following an incident.
- Cold sites are ideal for non-mission-critical data and tools. They provide restoration at a disaster recovery location, but because they do not mirror data prior to a disaster, these solutions require some downtime before resources are up and running again.
