| <p>The <code class="docutils literal notranslate"><span class="pre">commitlog_archiving.properties</span></code> configuration file can optionally set commands that are executed when archiving or restoring a commitlog segment.</p> |
| <div class="section" id="options"> |

| <h3><code class="docutils literal notranslate"><span class="pre">archive_command=<command></span></code><a class="headerlink" href="#archive-command-command" title="Permalink to this headline">¶</a></h3> |
| <p>One command can be inserted with %path and %name arguments. %path is the fully qualified path of the commitlog segment to archive. %name is the filename of the commitlog. STDOUT, STDIN, or multiple commands cannot be executed. If multiple commands are required, add a pointer to a script in this option.</p> |
| <p><strong>Example:</strong> archive_command=/bin/ln %path /backup/%name</p> |
| <p><strong>Default value:</strong> blank</p> |

| <h3><code class="docutils literal notranslate"><span class="pre">restore_command=<command></span></code><a class="headerlink" href="#restore-command-command" title="Permalink to this headline">¶</a></h3> |
| <p>One command can be inserted with %from and %to arguments. %from is the fully qualified path to an archived commitlog segment using the specified restore directories. %to defines the directory to the live commitlog location.</p> |
| <p><strong>Example:</strong> restore_command=/bin/cp -f %from %to</p> |
| <p><strong>Default value:</strong> blank</p> |

| <h3><code class="docutils literal notranslate"><span class="pre">restore_directories=<directory></span></code><a class="headerlink" href="#restore-directories-directory" title="Permalink to this headline">¶</a></h3> |
| <p>Defines the directory to scan the recovery files into.</p> |

| <p>Restore mutations created up to and including this timestamp in GMT in the format <code class="docutils literal notranslate"><span class="pre">yyyy:MM:dd</span> <span class="pre">HH:mm:ss</span></code>. Recovery will continue through the segment when the first client-supplied timestamp greater than this time is encountered, but only mutations less than or equal to this timestamp will be applied.</p> |
| <p><strong>Example:</strong> 2020:04:31 20:43:12</p> |
