Well you haven't explained much.  "Daily registry backup" doesn't really
mean anything in TSM terms.  It could be a schedule that is setup to do a
"daily registry backup" (dsmc backup registry).

Where do you see "daily registry backup"?

On NT and w2k with most recent clients, the registry is backed up with the
system objects (which is included by default with the "ALL-LOCAL" DOMAIN.

You can also backup the registry with the "backup registry" command.
