Disaster recovery of backup exec server

I have a BE 2014 server with only target storage which is dedup storage. I do not have any other disk or tape storage. 

I am guessing its a bad idea to have even the BE server backup go to the dedup storage cos i am not sure how to recover in case the media server crashes. 

For the backup exec server to be recovered I believe i need the catalog and data folder first before I can import the dedup folder ?

as per TECH187911 I need to backup the disk/drive where the dedup storage resides and back it up to tape. But in my case I dont have a tape device 

Any other alternatives ?
