Audit log processing failure

It’s my understanding that if the Robots server can’t send logs to Orchestrator, the Robots server will keep those logs locally until a connection is re-established with Orchestrator. My question is what happens if Orchestrator can’t send the logs to an SQL server? Does Orchestrator do the same thing that the Robots server does and keep a local copy on Orchestrator until the connection to SQL is reestablished?
Thanks!
