Using this set up doesn't this mean the backups would go to the tape first
if the tape pol were the primary pool? Wouldn't that make backups slower?
How do I get backups to go to the disk first while still having different
expiration for each?

It doesn't work that way.

If you want to keep a copy of inactive files on tape forever, you need to
have a primary storage pool on tape (call it "ONSITE" for the purpose of
this note).  So, BACKUPS will migrate data to ONSITE. You'll also use
BACKUP STG to populate OFFSITETAPE, mostly from BACKUPS, but possibly from
ONSITE just to be safe.

You can use a migration delay on ONSITE to keep recent (<30 days, if you
want) files from migrating tape, but eventually some active files will
migrate to ONSITE.

It might make more sense to use your disk storage as an ACTIVEDATA storage
pool, not a long-term primary storage pool. Your inactive data would still
go to tape, but your active data, even the oldest, would be on disk (as
well as on tape).

Hope this helps,
Nick
