摘要： A method and system for storage checkpointing of an independent computer application. The independent computer application is launched by a coordinator; and the coordinator installs at least one of an exec interceptor and a fork interceptor. The coordinator also installs at least one file operations interceptor for all file operations and registers the independent computer application with the coordinator. The independent computer application is run and the at least one file operations interceptor is called upon encountering a file operation. The file operations interceptor logs a file event in a file operations database and passes the operation to at least one of a file system, an operating system, at least one or more device drivers, and a storage disk via a storage interface. The file operations interceptor also verifies that the file operation has been issued.

摘要： A method and system for checkpointing at least one application in an application group. At least one full checkpoint and at least one incremental checkpoint are created for the application in the application group. The at least one incremental application checkpoint is merged against the at least one full application checkpoint, and checkpointing across all applications in the application group is synchronized. A storage checkpoint is taken for at least one of the full checkpoint and the incremental checkpoint, and memory and storage checkpoints are synchronized and consistent.

摘要： A system includes a multi-process application that runs. A multi-process application runs on primary hosts and is checkpointed by a checkpointer comprised of at least one of a kernel-mode checkpointer module and one or more user-space interceptors providing at least one of barrier synchronization, checkpointing thread, resource flushing, and an application virtualization space. Checkpoints may be written to storage and the application restored from said stored checkpoint at a later time. Checkpointing may be incremental using Page Table Entry (PTE) pages and Virtual Memory Areas (VMA) information. Checkpointing is transparent to the application and requires no modification to the application, operating system, networking stack or libraries. In an alternate embodiment the kernel-mode checkpointer is built into the kernel.

摘要： A computer readable medium and method providing checkpointing to Windows application groups, the computer readable medium having computer-executable instructions for execution by a processing system. The computer-executable instructions may be for launching an application and creating one or more application threads, receiving a checkpoint signal by an application thread, and entering a checkpoint Asynchronous Procedure Call (APC) handler at IRQL APC_LEVEL, the APC handler disposed in a kernel module, acquiring an ETHREAD block and user-mode context for the application thread, and examining an execution state of the one or more application threads at a time of the checkpoint signal.

摘要： A system and method thereof for performing loss-less migration of an application group. In an exemplary embodiment, the system may include a high-availability services module structured for execution in conjunction with an operating system, and one or more computer nodes of a distributed system upon which at least one independent application can be executed upon. The high-availability services module may be structured to be executable on the one or more computer nodes for loss-less migration of the one or more independent applications, and is operable to perform checkpointing of all state in a transport connection.
