Description Patrick C. F. Ernzer 2005-07-20 12:10:16 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
As per BZ #163683.

It would be nice if pax supported the incremental backup functionality that tar supports. This will allow using it with amanda

Version-Release number of selected component (if applicable):

How reproducible:
Didn't try

Steps to Reproduce:
1. use amanada to backup a machine that uses SELinux
2. find out that amanda uses tar which does not support EAs and ACLs
3. try to find an alternative to tar for amanda to use

Actual Results:  pax is lacking required functionality

Expected Results:  pax being usable with amanda

Additional info:
Comment 1 Patrick C. F. Ernzer 2005-07-20 12:16:12 EDT
BZ #163716 has been also opened requesting the same from pax.

IIRC the consensus on tech-list was that while both star and pax are not
perfect, pax is preferable.
Comment 2 Peter Vrabec 2005-08-03 11:29:10 EDT
Do u think pax is good alternative? It doesn't support EAs and ACLs, does it.
Comment 4 Peter Vrabec 2006-09-06 07:55:32 EDT
Patrick, I think this bug is not relevant since we have star and tar>=1.15.90-6 with incremental 
backup functionality and EAs and ACLs support. It would be significant amount of work to add 
this functionality to pax.

Comment 5 Patrick C. F. Ernzer 2006-09-06 09:01:09 EDT

fair enough if tar>=1.15.90-6 now supports EAs and ACLs the aim of having our
amanda package making a real backup again (i.e. with EA and ACL) is fulfilled.

Will 1.15.90-6 that go into RHEL5 (Beta 1 of it still has 1.15.90-5)?
Comment 6 Peter Vrabec 2006-09-06 10:42:18 EDT
It was build on Aug 10 2006, so I guess it should be there
