If you want a solution that allows to append files to an archive, while
allowing compression, take a look at FileNode, a module that has been added
to the latest PyTables package (www.pytables.org). You can see the
documentation (and tutorials) for the module here:

http://pytables.sourceforge.net/html-doc/c3616.html

It supports the zlib, ucl and lzo compressors, as well as the shuffle
compression pre-conditioner.
