If you intend on using RMAN the only advice would be to steer clear of partial recovery, e.g. say: RMAN> recover database until logseq 100;
When you start the database you will need to follow on with: "alter database open resetlogs".
This will change the database incarnation number making it different from the value we hold in the Delphix engine, effectively acting like a rewind, but not telling the Engine about it. This will break things because we won't know which snapshot is the parent; so partial recovery is not something we would support. (Rewinding the VDB prior to the restore would bring you back out of this scenario).
