Abstract
Systems and methods are disclosed herein to automatically replicate virtual machine image (VM) files on secondary VM computing devices, from a primary VM computing device. The secondary VM computing devices are automatically selected by constantly reviewing the operating parameter values (e.g., cost of resources, power consumption, etc.) of a number of secondary VM computing devices available of storing VM image replicas. The replica of the primary VM image is stored in the secondary VM computing devices in geographically disparate cloud locations. The primary VM image is automatically broken into constituent data blocks stored in an active index, which is compared against a stale index of data blocks. When an update is detected in the primary VM image, the comparison of indices will indicate that there is new data. Only the new data is used to update the secondary VM images, thereby reducing network traffic and latency issues.
