SD taking *extremely* long when FileVault volumes are present

I think it is time for SuperDuper to handle FileVault-encrypted volumes specially.

I've just ran SD and got: "Elapsed time: 1:33:09". That is for a backup of a 120GB HDD to a 80GB external drive. 20GB of this data is a FileVault sparseimage (my home directory).

From what I noticed, SD seems to do the following:
1. Read the sparseimage from the external drive to compare and see if an update needs to be done
2. Write the sparseimage with new changes
3. (that one I can't understand) rewrite the sparseimage AGAIN

I have no idea why it would do #3 above but I clearly saw it while repeatedly listing the directory where the sparseimage sits on the external HDD.

These backup times make SD almost useless.

My suggestion would be to implement a config option letting me specify which files are to be copied unconditionally -- bypassing the "smart" mechanism. In my case, I know that I want to copy the full sparseimage on every backup -- doing comparisons on it is just too expensive.

Hoping for a fix...
