Abstract: Exemplary embodiments provide access to an updated file performed by at least one processor, wherein responsive to receiving a first list of logical block addresses (LBAs) and a second list of LBAs for an update, wherein the first list of LBAs is mapped to a first list of physical block addresses (PBAs), and the second list of LBAs is mapped to a second list of PBAs, the method, comprising: atomically remapping the first list of LBAs so that the first list of LBAs is mapped to the second list of PBAs; trimming a mapping of the first list of LBAs to the first list of PBAs; and unmapping the mapping of the second list of LBAs to the second list of PBAs.

Abstract: Exemplary embodiments provide access to an updated file performed by a computer having at least one processor, wherein responsive to an application receiving an update comprising modified content of an old file, a new file is created into which the modified content is copied, while access to the old file is maintained, wherein old file logical block addresses (LBAs) are mapped to old file physical block addresses (PBAs), and new file LBAs are mapped to new file PBAs, the method, comprising: automatically swapping the mapping of the old file LBAs from the old file PBAs to the new file PBAs; trimming the mapping of the old file LBAs to the old file PBAs; and clearing the mapping of the new file LBAs to the new file PBAs.
