Depends what you are looking to do. If you want to protect your self from your self/other admins making changes, then vShield Manager currently doesn't maintain a listing of previous versions.
If you want to protect against the loss of a vShield Edge, then all the configs etc.. are stored and deployed in the vShield manager, so backing up the manager is a very important task. There are ID's used in rules and the Edges that will restrict what you can do for restores (see below)
For purposes of DR, backup your vShield manager config, and in the event of a DR situation, you will deploy a new vShield Manager appliance, restore the config, and point it to the restored version of your vCenter. vShield manager is rather tied to one vCenter, so you can't deploy edges to a DR vCenter, or SRM the vShield manager/edges. We are suffering pains through this, and VMware doesn't have much in the way of plans in the future vCNS/NSX. Sadly the use case of shifting vShield Edges and their VM's to alternate locations seemed to be a great surprise to them!
Thanks for your reply.
My use case is exactly the first one you taleked about an it is a service for Organization admin and not Cloud Admin.
As an Org Admin, I should be able to restore the state of my Edge GW config to a previous state without impacting the other organizations.
One approach is to copy the rules out into a safe place. Slow, and painful for larger systems or many Edge's. VSM will not export individual firewalls. However, the tech-support logs for the Edge will contain all the rules as well. You could easily get those logs.
Alternatively, backup the Edge appliance just like you would backup any other VM within your tenancy. An Edge will work even if it looses its connection to VSM. But there is no import rule tools or export short of the support logs.
This would be a very nice addition to VSM and the API and vCloud Director/vCAC to save the data...

I know this is an old post but it's along the same lines as a question I asked about 3 years ago and only in the last year did I come up with a solution. These import/export scripts should do the job.
