For our local sites we vault daily, i.e we send copypool tapes to the vault
daily. For our remote sites since we do not any local vault person, we have a
contract with a company and the copypool tapes are sent to the vault once a
week.
The DR tapes should be sent evry day if possible else in case of a real
disaster you would lose over a weeks data if you send DR tapes once a week.
