  • Publication number: 20190227733
    Abstract: In a method for deleting a cascaded snapshot, a storage device includes a logical volume corresponding to a plurality of cascaded snapshots. The plurality of cascaded snapshots comprises at least a first snapshot, a second snapshot, and a third snapshot. The second snapshot is a parent snapshot of the first snapshot, the third snapshot being a child snapshot of the first snapshot. The storage device receives an instruction for deleting the first snapshot. The first snapshot comprises target data. The storage device migrates information of the target data to the second snapshot. Further, the storage device sets a parent snapshot identifier corresponding to the third snapshot to an identifier of the second snapshot, and deletes the first snapshot.

  • Patent number: 9471461
    Abstract: A computer implemented method for maintaining a program's calling context correct even when a monitoring of the program goes out of a scope of a program analysis by validating function call transitions and recovering partial paths before and after the violation of the program's control flow. The method includes detecting a violation of control flow invariants in the software system including validating a source and destination of a function call in the software system, interpreting a pre-violation partial path responsive to a failure of the validating, and interpreting a post violation path after a violation of program flow.
