Abstract
A pass-through snapshot engine records lifecycle data and chronological status of files or objects, in one or more pass-through snapshots during a backup. If there is an abort, the pass-through snapshot engine freezes the pass-through snapshot(s) and terminates the backup. To restart after the abort, the pass-through snapshot engine sends one or more pass-through snapshots to the backup agent. The backup agent restarts the backup, and enforces states of lifecycle and chronology to files or objects, and discards files or objects that have already been backed up to the target device, in accordance with the one or more pass-through snapshots.
