What Comprises a Bellacom Disaster Recovery Solution?
An effective disaster recovery solution typically includes a mix of the following components:
During replication, files are copied from a primary location to a secondary location for use in the event of a system failure.
While similar to replication, clustering is performed on a volume level to provide scalability, load balancing and system availability. It allows automated failover between servers in the cluster and facilitates close monitoring of critical applications and their components.
Mirroring creates dynamic, real-time copies of data volumes which lessens the risk of data loss. Mirroring is accomplished by using Level 1 Redundant Array of Independent Disks (RAID) features through the motherboard or via a controller card built into a dedicated disk array.
Virtualization software has found new uses in disaster recovery planning. Optional tools allow virtual machines to transfer or fail over to dissimilar hardware, enabling the virtual machine to be online in minutes.
A failover site 100+ miles or more from your primary location can help ensure that secondary systems are not negatively impacted by local natural disasters.
