Hi @blaram

I would recommend this white paper as a starting point:

Re: EMC Unity : Availability of snapshot...

copy just creates another snapshot with the same content

possible use case if you want to attach it to a different server

you will get a warning when deleting a LUN that this also deletes its snapshots

If you really want to protect against LUN deletion you need to create a relica (full copy) which can be on a different pool (but doesnt need to in order to protect against LUN deletion)

I would suggest to download and install the UnityVSA

There you can check how the system behaves
