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. -- Francesco Paolo Lovergine , Wed, 28 December 2020 10:54:01 +0100
