The criteria for policies to be eligible for transparent snapshots are:
Policies created before PowerProtect Data Manager 19.9 will not automatically start to use TSDM upon upgrade to 19.9 and later. The same is true for policies created in 19.9 or earlier with Capacity Optimization mode: TSDM will not be used automatically upon upgrade to PowerProtect Data Manager 19.10. The Data Mover type would be updated the next time the policy is edited or when it is explicitly configured. When a full backup would be performed for the first time, TSDM operates then and when the policy option is switched between Performance and Capacity Modes. TSDM remains the Data Mover when Performance Optimization mode is switched to Capacity Optimization mode, and conversely.
