Abstract
Data backup systems and methods are provided to asynchronously mirror in-memory checkpoint images generated by a process executing on a host system. For example, a data backup system is configured to: receive a checkpoint request message to store a copy of a checkpoint image which includes memory pages residing in a first memory region of memory on the host system; pull a copy of metadata associated with the memory pages from a second memory region of memory on the host system; pull a copy of the memory pages of the checkpoint image from the first memory region; generate a copy of the checkpoint image using the memory pages and associated metadata pulled from the host system; and store the copy of the checkpoint image in a storage device with an in-memory format that is the same as the checkpoint image residing in the first memory region on the host system.
