Oracle DUL performance/speed

Hi gurus,
I have a customer , ct has a 18T database.
Unfortunately, the backup is no use.

CT want to retrieve the data from these datafiles using DUL.

Assume ct has redundant hardware resource.

Please help to estimate:

How long will cost DUL to retrieve all the contest from the 18T datafiles?



FYI pls check this link:
