When you run bpduplicate, it doesn't consider how many copies exist.
It will do just as you ask and create a new copy, as long it doesn't
exceed the "max backup copies".
The simple answer is, if you don't want another copy, don't run it
again.
Vault is a little more intelligent. You specify a target volume pool,
and if a copy already exists *in that pool*, it won't make another.
bpduplicate is the manual way of duplicating, that circumvents the
"artificial intelligence" of Vault.
Cheers,
Paul
