INSTALLATION: Thank you for trying rdiff-backup. To install, run: python setup.py install The build process can be also be run separately: python setup.py build The default prefix is /usr, so files are put in /usr/bin, /usr/share/man/, etc. An alternate prefix can be specified using the --prefix= option. For example: python setup.py install --prefix=/usr/local The setup script expects to find librsync headers and libraries in the default location, usually /usr/include and /usr/lib. If you want the setup script to check different locations, use the --librsync-dir switch or the LIBRSYNC_DIR environment variable. For instance, python setup.py --librsync-dir=/usr/local build instructs the setup program to look in /usr/local/include and /usr/local/lib for the librsync files. Finally, the --lflags and --libs options, and the LFLAGS and LIBS environment variables are also recognized. Running setup.py with no arguments will display some help. REQUIREMENTS: Remember that you must have Python 2.2 or later and librsync 0.9.7 or later installed. For Python, see http://www.python.org. The rdiff-backup homepage at http://rdiff-backup.nongnu.org/ should have a recent version of librsync; otherwise see the librsync homepage at http://librsync.sourceforge.net/. For remote operation, rdiff-backup should be in installed and in the PATH on remote system(s) (see man page for more information). The python modules pylibacl and pyxattr are optional. If they are installed and in the default pythonpath, rdiff-backup will support access control lists and user extended attributes, provided the file system(s) also support these features. Pylibacl and pxattr can be downloaded from http://pylibacl.sourceforge.net/ and http://pyxattr.sourceforge.net/. TROUBLESHOOTING: If you have everything installed properly, and it still doesn't work, see the enclosed FAQ.html, the web page at http://rdiff-backup.nongnu.org/, and/or the mailing list.
