Backup Tool batch of questions

[Nicolas <nt...@gmail.com>]

Hi,

As you can see in Subversion (in contrib/backup/), I have started "real"
work on this project. I still have a few questions. Can you please help me
on those?

Can you please confirm me the visibility of the Namespaces. To me, it is the
whole repository. Is it correct? I will post its backup class soon.

I can't find a way to use NIO with java.util.zip. I will probably use nio on
some parts but mostly io unless someone can tell me how to use nio with zip.
Any ideas please?

Last points but the most important ones: here is the list of the resources I
intend to backup. If you see any other resource to backup, please tell me.

- the backup configuration file  (we kind of need it for restore)
- the repository (through copying it into another PM)
- All workspaces
- Namespaces
- NodeType
- NodeVersionHistories
- Repository.xml
- all workspaces.xml

Thank you all for your great help on this.

Nico

what exaclty do you meen? there is a global namespace registry. but
the namespaces can be locally (per session) remapped. for your
application, you don't need to deal with the local namespaces. but you
must of course export them. i suggest to include the mappings in the
namespace registry in your backup.

apparently this is an old issue:
  http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4773980

i guess, that the parsing overhead when restoring the repository is
way bigger than the i/o speed improvement you'll get from nio. but
maybe i'm wrong. you still can use nio in the more general layers of
you app. the persistence part can still deal with details of how to
write it to disk.

regards, toby
