I've got two points

1. With this version, the command 'zarafa-admin --list-orphans' shows all companies in a multi tenant environment as 'Users without stores'.
I've checked it and all companies do have a store.

2. What can the new zarafa-backup-plus do?
The announcement does have some pointers, but I wonder if this is intended to do a disaster recovery with?
So asked differently: does this back-up and restore *all* information available in the Zarafa database, that you would otherwise have when you do a straight backup/restore of the database + attachments?
