cdot snapvault setup and 7 year retention


I have been reading a lot of posts and ONTAP documentation but still confused as to how this should be setup.

Requirement is to have snapshots as below.

Source:  every 4hr  for 2 days
 daily for 7 days
 weekly  for 4 weeks
Destination: daily 30 days
  weekly 8
  monthly 12
  yearly  7

I have followed the Snapvault express guide to set this up on a test volume but still not clear and can't get it to work as expected. The step are

1. create a new vol on destination
2. create a new schedule on destination ( use default daily to run overnight)
3. create snapshot policy on source and apply to source vol
4. create a snapvault policy on destination.
5. create the snapvault relationship on destination

What is confusing me is step 3 and 4.

I have created the snapshot policy in step 3 on the cluster level, does this have to be on the svm level ??, do I add the local schedules and the destination schedules to this same policy ??
As we don't want to keep monthly or yearly on the primary I set the retention to 0 ( or should this be 1 ??)

Any help will be much appreciated.

I'm afraid you have to keep 1 on the primary. 

You probably wont be able to allow space to keep 1 yearly, suggest using monthly instead.

This was supposed to be resolved in a later version of ontap.
