A <dfn>snapshot</dfn> is a backup of the current state of a session. It differs
|
|
from a simple save by allowing branching. It is a "frozen" version of the session
|
|
at a certain point in time.
|
|
</p>
|
|
<p>
|
|
For example, creating a snapshot before changing the entire arrangement of a
|
|
piece, or drastically altering the signal processing provides a reference to
|
|
come back to, should that not work out.
|
|
</p>
|
|
<p>
|
|
This is accomplished by using either of the <kbd class="menu">Session >
|
|
Snapshot</kbd> menus. A small dialog will appear, allowing to enter a name for
|
|
the snapshot. The default name is based on the current date and time.
|
|
</p>
|
|
|
|
<p>
|
|
The difference between the two snapshot menus is:
|
|
</p>
|
|
<table>
|
|
<tr>
|
|
<td><kbd class="menu">Snapshot (& keep working on current version)...</kbd></td>
|
|
<td>Saves a snapshot of the session, but keeps the current session active, i.e. any
|
|
subsequent <kbd class="menu">Session > Save</kbd> will overwrite the original
|
|
session, and the snapshot will remain unchanged.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><kbd class="menu">Snapshot (& switch to new version)...</kbd></td>
|
|
<td>Saves a snapshot of the session, and uses this snapshot as the current
|
|
active session, i.e. any subsequent <kbd class="menu">Session > Save</kbd>
|
|
will overwrite the snapshot, and the original session will remain unchanged.</td>
|
|
</tr>
|
|
</table>
|
|
|
|
<p>
|
|
Any number of snapshots can be created.
|
|
</p>
|
|
<p class="warning">
|
|
Creating a snapshot does <strong>not</strong> modify the session,
|
|
nor does it save the session. Instead, it saves an alternate version
|
|
of the session, within the session folder. The snapshot shares all data
|
|
present in the session.
|
|
</p>
|
|
|
|
<h2>Switching to a Snapshot</h2>
|
|
<p>
|
|
Switching to an existing snapshot is done by navigating the
|
|
<a href="@@the-snapshot-list">Snapshot List</a> and clicking the the name of
|
|
the desired snapshot. Ardour will switch to the snapshot, and, if there are
|
|
unsaved changes in the current session, offer to save them.
|
|
</p>
|
|
|
|
<h2>Starting Ardour With a Snapshot</h2>
|
|
<p>
|
|
Since a snapshot is just another session file stored within the session
|
|
folder, that "version" can be chosen when loading an existing session.
|
|
The browser in the "Open Session" dialog will show an expander arrow for
|
|
sessions that have more than one session file (i.e. snapshots)
|
|
present. Clicking on it shows the list, and then clicking on the name of the
|
|
snapshot loads it.
