<li>Right now the only modes supported are reading from standard input and writing to standard output. FUSE mounts and NBD servers may be added later if someone contributes the code.</li>
<li>The program keeps all known blocks in an in-RAM hash table, which may create scalability problems for very large repos (see <a href="#scalability">below</a>).</li>
<li>The only encryption mode currently implemented is <code>AES-128</code> in <code>CBC</code> mode with <code>PKCS#7</code> padding. If you believe that this is not secure enough, patches are welcome. Before you jump to conclusions however, read <a href="http://www.schneier.com/blog/archives/2009/07/another_new_aes.html">this article</a>.</li>

<li>The only compression modes supported are LZMA, which suits backups very nicely, and LZO, which enables much faster backups at the expense of storage size. More compression modes could be supported, eg zlib.</li>
<li>It's only possible to fully restore the backup in order to get to a required file, without any option to quickly pick it out. <code>tar</code> would not allow to do it anyway, but e.g. for <code>zip</code> files it could have been possible. This is possible to implement though, e.g. by exposing the data over a FUSE filesystem.</li>
<li>There's no option to delete old backup data yet. The possibility is all there, though. Someone needs to implement it (see <a href="#improvements">below</a>).</li>
<li>There's no option to specify block and bundle sizes other than the default ones (currently <code>64k</code> and <code>2MB</code> respectively), though it's trivial to add command-line switches for those.</li>
