                        <text>This path is used to store data for the asynchronous <cmd>archive-push</cmd> and <cmd>archive-get</cmd> command.

                        The asynchronous <cmd>archive-push</cmd> command writes acknowledgements into the spool path when it has successfully stored WAL in the archive (and errors on failure) so the foreground process can quickly notify <postgres/>. Acknowledgement files are very small (zero on success and a few hundred bytes on error).

                        The asynchronous <cmd>archive-push</cmd> process queues WAL in the spool path so it can be provided very quickly when <postgres/> requests it.  Moving files to <postgres/> is most efficient when the spool path is on the same filesystem as <path>pg_xlog</path>/<path>pg_wal</path>.

                        The data stored in the spool path is not strictly temporary since it can and should survive a reboot.  However, loss of the data in the spool path is not a problem.  <backrest/> will simply recheck each WAL segment to ensure it is safely archived for <cmd>archive-push</cmd> and rebuild the queue for <cmd>archive-get</cmd>.

                        The spool path is intended to be located on a local Posix-compatible filesystem, not a remote filesystem such as <proper>NFS</proper> or <proper>CIFS</proper>.</text>

    <!-- COMMAND -->
    <operation title="{[project]} Command Reference">
        <description>The {[project]} Command Reference details all commands and options.</description>

        <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.  This includes all the options that may also configured in <file>pgbackrest.conf</file>.

        Non-boolean options configured in <file>pgbackrest.conf</file> can be reset to default on the command-line by using the <id>reset-</id> prefix.  This feature may be used to restore a backup directly on a repository 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>--reset-pg1-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>--pg-path</br-option> to force the restore to happen in a specific path, i.e. not the path used on the database host.

        The <id>no-</id> prefix may be used to set a boolean option to false on the command-line.

        Any option may be set in an environment variable using the <id>PGBACKREST_</id> prefix and the option name in all caps replacing <id>-</id> with <id>_</id>, e.g. <br-option>pg1-path</br-option> becomes <id>PGBACKREST_PG1_PATH</id> and <br-option>stanza</br-option> becomes <id>PGBACKREST_STANZA</id>.  Boolean options are represented as they would be in a configuration file, e.g. <id>PGBACKREST_COMPRESS="n"</id>, and <id>reset-*</id> variants are not allowed.  Options that that can be specified multiple times on the command-line or in a config file can be represented by separating the values with colons, e.g. <id>PGBACKREST_DB_INCLUDE="db1:db2"</id>.

        Command-line options override environment options which override config file options.</text>

                    It is tempting to name the stanza after the primary cluster but a better name describes the databases contained in the cluster.  Because the stanza name will be used for the primary and all replicas it is more appropriate to choose a name that describes the actual function of the cluster, such as app or dw, rather than the local cluster name, such as main or prod.</text>

                        There are some scenarios where a backup might still be desirable under these conditions.  For example, if a server crashes and the database cluster volume can only be mounted read-only, it would be a good idea to take a backup even if <file>postmaster.pid</file> is present.  In this case it would be better to revert to the prior backup and replay WAL, but possibly there is a very important transaction in a WAL segment that did not get archived.</text>

                        The purpose of this option is to allow offline backups.  The <path>pg_xlog</path>/<path>pg_wal</path> directory is copied as-is and <setting>archive-check</setting> is automatically disabled for the backup.</text>

                Note that <code>pg_create_restore_point('pgBackRest Archive Check')</code> and <code>pg_switch_xlog()</code>/<code>pg_switch_wal()</code> are called to force <postgres/> to archive a WAL segment.  Restore points are only supported in <postgres/> &gt;= 9.1 so for older versions the <cmd>check</cmd> command may fail if there has been no write activity since the last log rotation, therefore it is recommended that activity be generated by the user if there have been no writes since the last WAL switch before running the <cmd>check</cmd> command.</text>

For instance, if a backup was started on the backup server then running <cmd>stop --force</cmd> on the database server will shutdown the backup process on the backup server.</text>
