hdup for Debian
---------------

To use hdup you need to provide a minimal configuration file named
/etc/hdup/hdup.conf. An example file is provided in /usr/share/doc/hdup.
Details about its format are given in hdup.conf(5) man page.

See also the hdup man pages for other information.

Due to some inconsistencies in tar, as explained in 
http://lists.gnu.org/archive/html/bug-tar/2005-02/msg00057.html
hdup2 can misbehave: the ownership/permission information of 
directories/subdirectories are getting lost when restoring 
from backup. This is documented in

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=302790

There is a patch for tar available if you need to solve this issue
from scratch: /usr/share/docs/hdup/tar-1.15.1.patch but note that
it is not supported by neither tar upstream or its Debian maintainer.

A final note: hdup is not more maitained by upstream: no new features 
will be added in the future and the package is only fixed by the Debian
maintainers from time to time for building nd important bugs.
