<h2>Backup Status</h2>
<h3>Copying Backup Files</h3>
<p>The box makes an incremental backup each night. The backup is stored on the machine itself. You are responsible for copying the backup files off of the machine.</p>
<p>Many cloud providers make this easy by allowing you to take snapshots of the machine's disk.</p>
<p>You can also use SFTP (FTP over SSH) to copy files from <tt id="backup-location"></tt>. These files are encrypted, so they are safe to store anywhere. Copy the encryption password from <tt id="backup-encpassword-file"></tt> also but keep it in a safe location.</p>
<h3>Current Backups</h3>
<p>The backup directory currently contains the backups listed below. The total size on disk of the backups is currently <span id="backup-total-size"></span>.</p>
<table id="backup-status" class="table" style="width: auto">
<thead>
<th colspan="2">When</th>
<th>Type</th>
<th>Size</th>
<th>Deleted in...</th>
</thead>
<tbody>
</tbody>
