The behavior of the fail option and the default settings depend on whether the concurrent copies operation was configured in Vault or in NetBackup:
In NetBackup, if you choose , the entire backup job fails and no copies are made. In this case, normal NetBackup behavior ensures that a successful backup for this policy eventually occurs. That is, NetBackup automatically retries the backup if time permits and, the next time the backup window for the policy opens, NetBackup again tries to run the backup (regardless of the frequency of the schedule). NetBackup does this until the backup succeeds, although one or more backup windows may pass before the backup is successful.
