Vincent,
 
The XAR was exported from the same xwiki-enterprise-1.1-milestone-3 version of our xwik, so it should be ok, but is unreadable.
 
It's great having the Import/Export facility in XWiki but a separate Backup/Restore facility based on the code behind the Import/Export facility would be good ... something like http://confluence.atlassian.com/display/DOC/Administrators+Guide#AdministratorsGuide-dataandBackups (daily backups, etc) rather than having to backup via a database backup utility, and if you didn't have to attach an XAR file to import it as a backup you wouldn't have the constraints of attaching a file and importing/restoring would be more efficient.
 
Being able to backup and restore data easily is very important to my organisation ... most organisations.
 
Thanks,
 
Richard

Hi,
I had a problem with importing an XAR running xwiki-enterprise-1.1-milestone-3  and my WinZip program didn't recognise the XAR as zipped file like other XAR files. Is this a known problem?
You say you have a XAR that you cannot import in XE 1.1.M3. So the question is: where did you get this XAR from?
Has it been fixed in the latest releases? Is there anyway to recover the data in this 'corrupted' XAR?
Let's first understand your problem.
 
Could the Import/Export facility be develop to provide proper backups (as Confluence does) so you don't have to attach an XAR file to restore as a backup?
Could you describe a bit more what you call a "poper backup". I haven't used confluence for a while and I don't recall how it does it (I thought it was generating a zip containing XML files much like what xwiki does).

BTW for large databases we don't recommend using XARs (they should be reserved for applications import/exports I think) since attaching tens of MB isn't a good solution. For large DBs we recommend backuping the DB using the standard DB backup tools.

If you have some ideas for improving backups please let us know. That'd be cool.

Thanks
