VMware에서 마이그레이션 간소화

CloneManager supports both ‘online’ and ‘offline’ migration and replication targets. Targets are termed ‘online’ when they are running machines ready to instantly take over from the source system. Online targets have the advantage that they are ready to run and can takeover operations very quickly. An alternative exists in the form of virtual disk image files. Virtual machines can be captured as a complete image in the same way that a system drive in a physical machine can be captured as a single disk image. The image file contains everything including the OS configuration, applications, and data. System replication or migration can be performed to a virtual disk image file stored within a private or public cloud environment rather than to a running machine. This has a significant cost advantage as only the cost of cloud storage is required to maintain these image files rather than storage plus compute resources. Offline replication can be a cost-effective solution when Recovery Time Objectives (RTO) are less demanding. Post replication network changes can also be scripted for both online and offline migrations.
