Amazon Elastic Disaster Recovery vs Cristie CloneManager

Amazon Elastic Disaster Recovery replicates on-premises and cloud-based applications to AWS for recovery with reduced downtime and data loss. It can launch recovery instances from the latest server state or a selected earlier point in time, support non-disruptive recovery drills and fail recovered applications back to their source environment. Sources include physical servers, VMware vSphere, Microsoft Hyper-V, other cloud providers and EC2 instances recovering to another Availability Zone or Region. Supported Windows and Linux workloads include Oracle, MySQL and SQL Server databases and SAP. The service can replicate AWS network settings such as subnets, security groups, route tables, internet gateways and network ACLs. Post-launch actions can run Systems Manager commands or automations. The console shows servers, events and metrics. Pricing is $0.03 a month, billed hourly per actively replicating source server. There is no free plan.

Cristie CloneManager Replication provides continuous system replication across physical, virtual and cloud environments. It supports file-based and block-based replication; block-based replication can lower recovery point objectives compared with file-based replication. Replication can target virtual disk image files in VHDX, QCOW2 and VMDK formats, as well as AWS, Azure, Oracle Cloud and S3 blob storage. The software monitors source systems and can automatically fail over after an outage, with DNS changes if needed. Multiple systems and their failover and failback can be managed through one interface. Teams can create sandbox test environments, including on physical systems, without interrupting continuous replication. RPO monitoring includes reports and email notices when replication falls outside target RPOs. The supported systems matrix includes Windows and Linux and virtualization platforms such as VMware vSphere, Hyper-V, AWS EC2, Microsoft Azure and Oracle Cloud Infrastructure. Replication costs $500 a year per protected system, with 12 months of support and maintenance. A free trial is offered, but no fixed duration is stated.
