<h2>One archiver. Every defense your data needs.</h2>
<p class="lead">Borg stores your files as content-defined chunks. Identical chunks are stored
exactly once — across files, across machines, across years of history.</p>
<div class="features">
<div class="feature">
<span class="glyph" aria-hidden="true">▣</span>
<h3>Space-efficient storage</h3>
<p>Content-defined chunking deduplicates everything in the repository. Daily full
backups cost little more than the changes since yesterday.</p>
</div>
<div class="feature">
<span class="glyph" aria-hidden="true">⬢</span>
<h3>Authenticated encryption</h3>
<p>AES encryption with cryptographic authentication. Your backup server never
needs to be trusted — it only ever sees ciphertext.</p>
</div>
<div class="feature">
<span class="glyph" aria-hidden="true">◧</span>
<h3>Compression</h3>
<p>Pick your trade-off: lz4 for speed, zstd for balance, zlib and lzma for maximum
squeeze — or none at all.</p>
</div>
<div class="feature">
<span class="glyph" aria-hidden="true">⌖</span>
<h3>Mountable archives</h3>
<p>Mount any archive as a regular filesystem with FUSE and browse old versions of
your files like any folder.</p>
</div>
<div class="feature">
<span class="glyph" aria-hidden="true">⌬</span>
<h3>Runs everywhere you do</h3>
<p>Easy installation on Linux, macOS, BSD and more — from distribution packages,
single-file binaries, or pip.</p>
</div>
<div class="feature">
<span class="glyph" aria-hidden="true">⚑</span>
<h3>Free & open source</h3>
<p>BSD licensed, developed in the open, and backed by a large, active community
since 2015.</p>
