VMware View end to end backup solution

Hi Folks,

We are running two different VDI environment one with 4.1 and 5.1,

5.1 environment was deigned for zero client and  deployed as linked clone floated pools, around 100 VDI session running on this pool,

4.1 environment was deigned for end user computing and deployed as dedicated desktop pool 1:1 mapping, around 500+ user are having own desktop session   

We do have SRM solution on site for all other production environment except above both VDI  So  I'm more curious to know about any good end to end backup and restore solution for my both VDI environment with lower downtime.

Thank you ,

Jim
