But you have to prevent log files reusing while you copy data files. That's why I asked are 3 commands from pg_copy required and couldn't be backup accomplished by issuing single command ALTER SYSTEM BACKUP <dir | stdout (to copy data to client side)> (even from pgsql) so backup process would die with entire system -:) As for tape changing, maybe we could use some timeout and then just stop backup process.
