Data Replication for Disaster Recovery

For companies whose recovery time objective and recovery point objective for business-critical applications is a few minutes, data replication is an efficient strategy for disaster recovery.

Data replication is the process of copying data from a primary production server to a secondary backup server over a network so you have multiple, up-to-date copies of the data. For disaster recovery, replication usually occurs between a primary storage location and a secondary offsite location. Replication is a key technology for disaster recovery, and often works in combination with data deduplication, virtual servers, or the cloud to carry out its disaster recovery role.

Sometimes, when always-on or hot recovery sites are contracted from third-party suppliers, those site operators will specify replication solutions. Because duplicating IT assets essentially means multiplying IT costs by the number of recovery sites set up, this gets expensive fast. This also explains why it’s crucial to limit recurring costs for any replication solution, as bandwidth and personnel costs can quickly swamp equipment and software outlays.

Many customers are looking to use low cost secondary storage options such as the cloud for replication to reduce costs. Komprise provides automated policies to put a DR copy of data in secondary storage such as the cloud or object storage of the customer’s choice. This significantly lowers the costs of replication and disaster recovery. It also enables customers to leverage the cloud for disaster recovery.

Komprise is dead simple to use, it manages and replicates across on premise and clouds.
