How long it takes to recover is a big question. I have customers were
it fits the rule of thumb, about 1.5 times the save time to recover (not
including creating RAID sets or drive initialization) but if I remember
correctly, you have Domino and I suspect you use SAVDOMBRM. In this
case you will run into some intrigue restoring depending on your
directory structure. SAVDOMBRM does not save the parent directories, so
ownerships and authorities might not get put down as you expect.
One customer I just did recovery testing for took about 8 hours total
for a "21" save. Over 70 hours to recover because there were a shade
over 50 million IFS objects DB/2 went down in a snap, but the rest of
the system, not so much. This customer is now installing a brand new
CBU box with PowerHA to replicate his system since 3 - 4 days of
downtime would not be acceptable to the business. (remember disk init
is not all that fast and in a real recovery you will have to do it)
