This enumerated field names which specific, predefined stage of the BackupPolicy workflow one individual stage inside the FSM workflow of a scheduled BackupPolicy run represents. Because the underlying FSM always executes its stages in the same fixed order for every run, this value is how you identify, out of the whole set of rows for one job, exactly which step — such as the initial local snapshot step versus the later remote-transfer step — this particular row's Order/StageStatus/Retry values belong to. Example values follow a dotted convention like IFSMBACKUPLOCAL or IFSMBACKUPEXPORT identifying the concrete action that stage performs.
