QuantaStor’s grid technology enables users to deploy a highly efficient business continuity solution for remote backup and disaster recovery (DR) either locally, across global datacenters or in the cloud. QuantaStor SDS utilizes snapshots and remote replication protocols to create a complete copy of the selected storage volumes and network shares from the primary to secondary DR site. 

QuantaStor Disaster Recovery Features

Remote Replication
QuantaStor SDS appliances utilize technology that links multiple appliances into a single grid. Appliances can be accessed over local or wide-area networks linking data centers anywhere in the world. No matter where the data resides, the entire data center can be managed from a single web interface allowing remote replication of data to and from any appliance in the grid. 

Minimal Impact on Network Traffic
QuantaStor SDS is extremely efficient and has minimal impact on system performance. Once the DR policy has been established, it only replicates changes to the data set minimizing the impact on network traffic. All data going across the network is compressed to minimize network bandwidth utilization andis fully encrypted for maximum data security.  

Multi-directional Replication
Once a storage grid is established, any appliance can be a DR site for any other appliance as long as there is sufficient capacity available. The replication policy is not limited to only one replica. A single appliance can replicate to multiple appliances across the world for maximum protection.   

File Protection with Snapshots
QuantaStor's DR technology utilizes snapshots to create a copy of selected storage volumes and network shares from a primary to secondary appliance at a DR site. The configuration is managed by a user defined policy engine that dictates how often a snapshot copy is updated and how many prior snapshot copies of the data are retained. Snapshots provide a way to recover corrupted, modified or deleted files. They return the primary system to a point-in-time copy by automatically maintaining a history of all saved snapshots.

Single Console Multi-site Management
The QuantaStor SDS platform allows administrators to pool resources and manage local and remote appliance groups from a single web-based user interface. This feature allows a single administrator to manage multiple geographically dispersed locations.
