For SLP, you can setup using hierarchical structure so that SLP knows why copy to be the source. For example in your case.

SLP1:
  Backup1 --> disk1
     Duplication --> disk2
  Duplication --> tape1

Second duplication, taking this indentation, would get the source from disk1 (1st copy). If you set it to:

 

SLP1:
  Backup1 --> disk1
     Duplication --> disk2
         Duplication --> tape1

It would instead get the source from disk2 (2nd copy).

If using Vault, you basically "choose backup" from what disk pool, so if you disk1 is the 1st copy, just direct Vault to pick it up from there, simply as that.

There is no complication or issue using both SLP & Vault, as apart from duplication, they are designed for different purposes. Just be careful of the resource and scheduling, to make sure you don't go into media contention etc.
