Why each backup requires so much space?

hi there.
I've been using Superduper for a few days. And I've had the following problems

1st. I am using the network backup (imaging over network, destination is a linux raid box). But then, the superduper is unable to mount the network drive automatically. I tried to map mount the network drive as always, but the superduper is just unable to mount it until I manually input:
smb://SharedDrive/Volume_1

2nd. I've been using the backup-all files. The problem is. Although there is no significant file changes between each scheduled daily backup (I am using the smart update), each backup copies at least 200 MB. I also tried to backup the file after 4 day interval, with no big file changes. And the backup, as of now, has backed up 2.26G of data, and is still evaluating. Why it takes so much space?

Thanks

1. I don't know why this might be. We store an alias to the image on the share. When we load the settings, that alias is dereferenced which mounts the drive. You need to ensure your password/authentication information is in the keychain, but other than that, it should work.

2. We live compare the two drives, and we're going to copy any files that are different. How can you be sure that there are no "significant" changes? There are a lot of files on the drive, many of which are changed indirectly...

Thanks for answers.

1st. Will you please provide me an instruction on how to map a network drive? maybe I mounted the hard drive in a different way?

2nd. I run multiple manual updates within sort period of time (like 10min), and the only file change that i ever made is to created some text files and folders on the desktop. Even though, the files backed up are like 200MB...

1. Cmd+k mounts, but you have to make sure you add any authentication information into the keychain if prompted.

2. Again, your personal change does not reflect the changes made by the system, or to non-user files, or to caches, indexes, databases, etc...

Then I do have the right map and the keychain information..

I did not have any other program other than superduper and finder running..
The only other things I can think of are the quicksilver and spotlight, which keep on indexing files in my mac. Is there a way to know what are the files being backed up in the most recent update? What is expected backup file size assuming the system is in an idle state?

Thanks

There is no such thing as an 'inactive' boot volume, really, regardless of the number of applications you're currently running. There's no 'expected' backup size, really.
