No Content Role for Backups When Creating LVM Storage

Proxmox VE 1.9, upgraded from 1.7.

I want to backup to iSCSI. I followed the guide: http://pve.proxmox.com/wiki/Storage_Model
When creating the LVM storage, there is a field called "Content:". The only option I have is "Virtual Disks". I recall there being another content option to designate this storage as backup/snapshot storage. How do I resolve this problem, or otherwise finish allotting storage for my backups?

Hi,
you need an real filesystem for the backup-target. You can create an logical volume backup on the VG, format and mount it. But this isn't recommended because you run in trouble if you backup VM-disks from the same VG (due to lvm-snapshot).
If you only use this VG for backup it's ok.

Thank you for responding Udo.
I'm not sure I understand. Can I get clarification for what is meant by "real filesystem" or perhaps an additional explanation? Perhaps I wasn't clear...
The iSCSI target is mounted (as device /dev/sdc) via the open-iscsi initiator on the Proxmox VE 1.9 host OS (Debian Lenny), and formatted with ext4.
 
It it is already mounted, add a directory type storage which points to that directory. You can then use that storage as backup destination.
 
That last part is where I have the problem. I cannot designate any path for backup. The option is not in the dropdown box. I attach the target, format it, mount it, and then go through the steps to add it in the ProxmoxVE web interface, but when I get to the step of designating what the storage will be used for, the only options are Virtual Disks and ISO Images. (The wording may not be exact. I don't have access to that system right now.) I'm guessing there has to be a configuration file somewhere that would normally contain this option so I can select it in the web interface...
