+ An Ardour session is stored in a single folder on the computer's filesystem.
+ This makes <dfn>backup</dfn> very easy: any tool capable of backing up a
+ folder can be used to backup a session. The location of a session is picked when
+ it is created —by default it will be in the default session location,
+ which can be altered via <kbd class="menu">Edit > Preferences > General >
+ Session</kbd>.
+</p>
+<p>
+ The single folder approach also makes sharing a project easy. Simply copy the
+ session folder (onto a storage device, or across a network) and another Ardour
+ user (on any platform) will be able to use it.
+</p>
+<p>
+ There is one complication in both cases: a session may reference media files that are stored
+ outside of the session folder, if the user has opted not to select
+ <kbd class="optoff">Session > Import > Copy to Session</kbd> during import.
+ Backing up a session with embedded files will not create a copy of the session
+ containing those files. To bring those external files to the session folder,
+ the <a href="@@cleaning-up-sessions"><kbd class="menu">Session > Clean-up >
+ Bring all media into session folder</kbd> menu</a> can be used.

+<h2>Using the dedicated Zip/Archive Current Session tool</h2>

+
+<p>
+ The <kbd class="menu">Zip/Archive Current Session</kbd> tool is located in the
+ <kbd class="menu"> File > Archive…</kbd> menu.
+</p>
+<p>
+ It allows to create a single file containing everything usefull in the session,
+ to share it or back it up, conveniently compressed to a session-archive which
+ is a zip-file (tar.xz to be specific) containing all the audio, MIDI,
+ plugin-settings,... and the currently active session. Ardour can also extract
+ those bundles (<kbd class="menu">Session > Open…</kbd>).
+</p>
+<p>
+ As opposed to zipping the entire session-folder manually,
+</p>
+<ol>
+ <li>the session-archive only contains the current session-snapshot and only
+ files which are used</li>
+ <li>externally referenced files are included in the archive.</li>
+</ol>
