I didn't think sector by sector would work either but when I tried to do the backup without it I got an error saying it had to be done that way, then when I got to the part where you choose the type of backup incremental was there so I chose that to see what happens and it went through, and i know it worked because the night before I did the incremental backup I installed 3 updates from Apple that, after running the restore, were still there.
The full backup is 58.4 GB and the incremental is 4 KB they were done 9 days apart and I didn't do much with the system, I do most of my work in Vista.
NYC Coyote, you do not need to partition and format the drive before you run the restore, as I said before I ran the restore on a RAW drive no formatting, no partitions, Acronis handles it all, I went into the Vista disk management utility and deleted the partition from the last test I did just to make sure it wouldn't mess anything up.
very interesting, but still not 100% clear. 4kb sounds very small, but you say you didn't do much with it. If sector by sector then it sounds like it's taking the entire partition as one file and then whatever changed in addition to it, e.g. boot sector? still confused with that, sorry about my ignorance. Shouldn't you be able to open the incremental backup by Acronis and see what's inside the backup? At least that's what I can do with windows backups.
btw. to get a broken system back to run again it depends on how you start. if you keep the same hdd, then you don't need to partition the drive as all the partitions are already set correctly as you say. However, if you start with a new hdd, then you do need to partition and you have to make the partitions at least the same size as the images as NYC Coyote mentions. This can sometimes be painful if you don't get it exact and you end up with empty space between partitions which is difficult to move, expand etc between the two OSs.
also, ghost came to the rescue for the first time when I hosed my OSX. was able to put backed up partition back to drive and with time machine back-up got it to right before the most recent state before it got hosed...
will next try a backup and incremental on my macdrive partition and then do an incremental and see how that works.
edit1: tried to use backup files and folders in ghost on the macdrive. it went through the process until it actually tried to read the files for the backup and gave me an error:

Failed, Error a4bc001b running job: Leopard.
doesn't matter whether I pick one file/folder or the entire system. Not possible in ghost. I can still backup the entire partition though, but only as an image of the entire partition, which means no incremental backups either.
