> Just a heads up that Tim and I plan to finish up the backup tool soon.
> Given the strong feedback so far it will include the restore tool,
> however it won't include the extended attributes (file permissions on
> the backup of the [netlogon share]).
> Handling the extended attributes turns out to be harder than you might
> expect, while 'just' a couple more options to a tar command, testing
> it runs up against the fake xattrs we use in our selftest environment,
> which are not visible to tar.
> Likewise, for the online backup, the ideal option would be to query
> these over SMB and store the NT ACL directly into the tar xattrs via
> the python API. However this isn't available until python 3.x
> Finally, testing runs into the same issue, we can't just extract the
> files with tar because we need the xattrs put into the xattr.tdb.
> As the client task was literally named 'samba_backup is not tested'
> I'm loathed to add a feature I can't test.
> Therefore, I will be proposing the tool matching the existing
> samba_backup for features, but more importantly with the critical
> locking bug addressed.
> For the overly curious, the current WIP patches are part of this tree:
> Please let us know any further feedback we should be aware of when
> presenting these.

Hi Andrew, what does backing up another server online get you, that just
backing up the server the python code is running on doesn't ?
If the code has mostly been written by Aaron, why is the copyright
assigned to you ?
As I said before, get the locking bug code into Samba and backport it,
we can discuss the python backup script then.
