I note that it looks like pgbarman employs pg_receivexlog; I will check it out.

You expose yourself to race conditions with such methods if a checkpoint has the bad idea to recycle past segments that your logic is copying. So I would advise to not do that. Instead of using the archive command, you should also consider using pg_receivexlog combined with a replication slot. This brings way more control with the error handling. -- Michael
