SLP does not retry multistreaming backup if child job fails or is canceled
While a multistreaming backup job is running, if one child job is complete but another child job fails or is canceled, the storage lifecycle policy (SLP) does not retry the backup job.
Workaround:
Run the nbstlutil cancel -backupid <backup identifier> command to cancel the backup job and clean up the pending jobs.
Trigger a manual backup.
