Abstract: One example method includes receiving, at an IO journal, a new entry that identifies a respective disk location L, and data X written at that disk location L, and determining whether a location specified in an oldest entry of the IO journal is specified in any other entries in the IO journal. When the location specified in the oldest entry is not specified in any other entries in the IO journal, adding the new entry to the IO journal, and augmenting the new entry with undo data. Or, when the location specified in the oldest entry is specified in at least one other entry in the journal, setting data specified in the oldest entry as undo data for the next entry that identifies that location, and adding the new entry to the IO journal, and deleting the oldest entry from the IO journal.

Abstract: A live image of a virtual machine is disclosed. When generating a live image, an image of a virtual machine is generated. A journal is also generated that starts before a start time of the image and ends after the start time of the image. A live image is then generated by synchronizing the start time of the image with the journal. This includes evaluating or analyzing the journal relative to the backup to determine or synchronize the start time relative to the entries in the journal.

Abstract: One example method includes capturing IOs, adding the IOs to a journal, adding undo data to the journal for one or more locations, and using the IOs and the undo data to determine when, during a timespan defined by the journal, a backup could have been taken. This determination may involve the use of undo data which indicates what the content of a particular location was prior to the first IO directed to that location during the timespan defined by the journal.

Abstract: One example method includes receiving a notification that a backup has been created, performing an IO splitting process that includes duplicating one or more IOs issued by an application that is included in the backup so that there are two copies of each IO, storing one copy of each of the captured IOs in an IO journal, packaging the IO journal together with the backup to create a live image, and transmitting the live image to backup storage.

Abstract: A system can generate a neural network, wherein an output of the neural network indicates whether a first test of a computer code will pass given an input of respective results of whether respective tests, of a group of tests of the computer code, pass, and wherein respective weights of the neural network indicate a correlation from a group of correlations comprising a positive correlation between a respective output of a respective node of the neural network and the output of the neural network, a negative correlation between the respective output and the output, and no correlation between the respective output and the output. The system can apply sets of inputs to the neural network, respective inputs of the sets of inputs identifying whether the respective tests pass or fail. The system can, in response to determining that a first set of inputs of the sets of inputs to the neural network results in a failure output, storing an indication that the first test is dependent on a subset of the respective tests indicated as failing by the first set of inputs.
