Abstract
Method for making a consistent checkpoint of a page including at least one data object in a computer system having a primary and secondary storage, and a programmable software. The primary storage has at least one page which includes at least one original data object on the page. The computer system allows at least one write operation to modify at least one data object, and the page is written into the secondary storage during checkpointing. The method includes beginning the checkpointing, including at least one page in the primary storage into a group of pages to be checkpointed, altering at least one data object with at least one data write operation, marking at least one data object resulting from the data write operation, writing at least one of the data objects into the secondary storage, and altering the state of the pending data object to be the original data object.
