+ <text>Commands are used to execute the various <backrest/> functions. Here the command options are listed exhaustively, that is, each option applicable to a command is listed with that command even if it applies to one or more other commands.

+
+ Non-boolean options configured in <file>pgbackrest.conf</file> can be reset to default on the command-line by using the <id>no-</id> prefix. This feature may be used to restore a backup directly on a backup host. Normally, <backrest/> will error because it can see that the database host is remote and restores cannot be done remotely. By adding <br-option>--no-db1-host</br-option> on the command-line, <backrest/> will ignore the remote database host and restore locally. It may be necessary to pass a new <br-option>--db-path</br-option> to force the restore to happen in a specific path, i.e. not the path used on the database host.
+
+ If the <id>no-</id> prefix is used with a boolean option then the option is set to false.</text>
