Continue compression of a file

Hi,

I would like to know if there is a way to continue the compression of a file. I am using your library in a backup service and sometimes a user choose to backup a large file say 100 GB. Now, during the backup the user logs off, restarts or shut down the computer.

Currently, my code dumps the previous (unfinished) file and starts anew, which is a nuance since it already takes a long time to compress large files. So is there a way to continue where we last left off.
