IFW multipass vs singlepass backup time

Postby userX » Tue Sep 20, 2011 8:10 pm

last night i made a differential backup using IFW of my pc hardrive. i had the single pass parameter set, and i did not have the parameter set for backing up unused sectors. i looked at the time it took for both and it was the same amount even though the base was 18 times larger than the differential part. i suppose the equal times was due to validation on both?

in general what is the benefit of using single pass or multipass options with a differential backup?

From Terabyte Support in response to a similar question I posed in the
old News Groups "typically if everything is on the same drive
then multi-pass can be faster.".
