I assume these services do incremental backups for the most part.

If you have an encrypted volume, and you change its contents, can you
do an differential backup, or does that file change so much

In other word, suppose I have a 1 GB encrypted file that I back up on
an online service. I open the volume with truecrypt, and change a few
lines in a plain text file. How different is the encrypted file? Can
it be backed up against the existing backup file incrementally?
