Snapshot create and deletion sequence for imported vCenter VM

Hi. Is there a way to create new snapshot and delete its parent using Scheduled Action in order to reduce storage used. The VM was imported as a wild from our vCenter host. The sequence that I’m thinking to achieve is something like this:

On This Monday:
+New Monday

On This Tuesday:
+New Tuesday

On This Wednesday:
+New Wednesday

On This Thursday:
+New Thursday

On This Friday:
+New Friday



On Next Monday:
-Prev Monday
+New Monday

On Next Tuesday:
-Prev Tuesday
+New Tuesday

On Next Wednesday:
-Prev Wednesday
+New Wednesday

On Next Thursday:
-Prev Thursday
+New Thursday

On Next Friday:
-Prev Friday
+New Friday

so on. I have tried to schedule action for the creation of new snapshot and deleting parent snapshot with ID 0, but it seems like the ID is auto increment and to schedule a periodic action I need to specify disk ID which confuses me on how to achieve this. Thanks for the suggestions :smiley:
