VTL migration to tape/DR copypool

We have recently gotten a new VTL for our TSM server. The VTL is pretty much setup but I need to modify daily maintenance for it.
There are several things I would like to accomplish with it.

Keep seven days of backups on the VTL (VTLPOOL)
Copy all backups to tape (TAPEPOOL)
duplicate tapes for offsite (DRCOPYPOOL)

I think I know what I should do but I wanted some confirmation (or criticism) of what I am doing.
Will these steps do what I want?
Is this the best way to do it?
If it is not the best way what is the best way and why is it better?

For #1 I think I need to set this:

Code:

update stgpool VTLPOOL migdelay=7

For #2 and #3 I should put the following into the mainenance script:

Code:

/* copy everything from VTLPOOL to TAPEPOOL and DRCOPYPOOL */

PARALLEL

backup stgpool VTLPOOL TAPEPOOL wait=yes

backup stgpool VTLPOOL DRCOPYPOOL wait=yes

SERIAL

/* migrate to TAPEPOOL */

migrate stgpool VTLPOOL lo=0 wait=yes

/* ensure everything is in DRCOPYPOOL */

backup stgpool TAPEPOOL DRCOPYPOOL wait=yes

Thanks in advance to all who respond..
