[Duplicity-talk] Duplicity on OSX not supporting the fs attributes supported by the osx tar ?

[Antoine Tremblay]

Hi,
   I'm testing duplicity on osx with backup bouncer :
http://www.n8gray.org/code/backup-bouncer/

And I found to my surprise that duplicity seems to do worse then the
system's tar binary for example using osx 10.6 tar I get :

Verifying:    basic-permissions ... ok (Critical)
Verifying:           timestamps ... ok (Critical)
Verifying:             symlinks ... ok (Critical)
Verifying:    symlink-ownership ... ok
Verifying:            hardlinks ... ok (Important)
Verifying:       resource-forks ... ok (Critical)
Verifying:         finder-flags ... ok (Critical)
Verifying:         finder-locks ... ok
Verifying:        creation-date ... FAIL
Verifying:            bsd-flags ... ok
Verifying:       extended-attrs ... ok (Important)
Verifying: access-control-lists ... ok (Important)
Verifying:                 fifo ... ok
Verifying:              devices ... ok
Verifying:          combo-tests ... FAIL

But using duplicity I get :

Verifying:    basic-permissions ... ok (Critical)
Verifying:           timestamps ... ok (Critical)
Verifying:             symlinks ... ok (Critical)
Verifying:    symlink-ownership ... ok
Verifying:            hardlinks ... FAIL (Important)
Verifying:       resource-forks ... FAIL (Critical)
Verifying:         finder-flags ... FAIL (Critical)
Verifying:         finder-locks ... FAIL
Verifying:        creation-date ... FAIL
Verifying:            bsd-flags ... FAIL
Verifying:       extended-attrs ... FAIL (Important)
Verifying: access-control-lists ... FAIL (Important)
Verifying:                 fifo ... ok
Verifying:              devices ... ok
Verifying:          combo-tests ... FAIL

I tough duplicity was using tar, is it using it's own implementation ?
If so it is possible to switch to the system's tar ?

Or any other way to support osx extra file attributes... ?

I've check the discussion regarding the new file format.. is there any
development  on this ?

I have some time on my hands and could do work or implementing what is
needed for this to work... so pointers on where to start are very
appreciated...


Thank you!
