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.
A method for making a consistent checkpoint of at least one page comprising at least one data object in a computer system having at least one primary and at least one secondary storage, said primary storage having at least one page which comprises at least one data object on the said page, the computer system allowing at least one write operation to modify at least one data object of the page, and said page being written into said secondary storage during the checkpointing, wherein the method comprises steps of:
A programmable software product for making a consistent checkpoint of at least one page comprising at least one data object in a computer system arranged to have at least one primary and at least one secondary storage, said primary storage arranged to have at least one page which comprises at least one data object on the said page, the computer system allowing at least one write operation to modify at least one data object of the page, and said page being written into said secondary storage during the checkpointing, wherein:
A method for recovering at least one page comprising at least one data object from a consistent checkpoint in a computer system having at least one primary and at least one secondary storage, said secondary storage having at least one first page which comprises at least one data object and said secondary storage having at least one second page which comprises at least one data object having pending operation status of removal of the data object and information about the original location of the data object, wherein the method comprises steps of:
