I've tried the backup from the admin UI by creating a full backup just after an upgrade from 4.0.5 and the ldap backup directory was not created : backup is done (fast) and the full backup appears correctly in the interface but no ldap directory in /opt/zimbra/backup.
I did another full backup (command line) and this time the ldap directory was created.
But instead of seeying the two different full backups in the AdminUI, I can now only see the last one (command line).
I had a look on another server (upgraded two days ago).
On this one, in the AdminUI, I can see the first full backup and the first incremental backup (that seems correct).
If I look in /opt/zimbra/backup, there's a ldap directory but there's only the "incr-..." directory in it, no "full-...".
Is that normal/standard behaviour or is it a bug?
