IFW multipass vs singlepass backup time
Posted: Wed Sep 21, 2011 3:10 am
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?
