Recommended Database Recovery Model

I have a single Windows Server 2012 machine running MS SQL 2012. This server contains all of our databases for the vCloud infrastructure. As of now, all of the databases are using the Simple recovery model, except for the vCloud Director database which is using the Full recovery model. I was wondering what VMware recommends for this database, and if it's ok to switch it to Simple mode or not.

Please let me know.

Thanks!
