</item>
</steps>
<note style="tip">
<p>Scrollback data is stored in compressed and encrypted files on disk,
under the system’s default location for temporary files (usually
<file>/tmp</file>). These files are unlinked immediately after their
creation, and as such, do not show up in the directory listing. The
occupied disk space is freed up as soon as the corresponding terminal
closes.</p>
</note>
<note style="warning">
<p>Make sure you have sufficient disk space available for these temporary
files. If in doubt, monitor disk usage for example with the command
<cmd>du /tmp</cmd>.</p>
</note>
<note style="important">
<p>A giant scrollback buffer makes resizing the terminal window slower.
As a rule of thumb, resizing gets noticeably slow at around 1 million
lines.</p>
