3. Introduction
Breitenbush Project is a backup system that allows users from the general public to backup their files persistently from anywhere in the world using the Internet (see Figure 1).

5. Scorecard
Investigate Hardware demands of database redundancy technique.
We have started with simple pushes using a database model to store files.
No drawbacks in performance have been discovered using the database.
We need to confirm multiple clients using the database at the same time.
The desire is to let up to 20 clients use the system at a time.

6. Scorecard (continued)
Get a preliminary connection from Client to Server up.
A preliminary connections module was designed and implemented.
Connections to the database are now possible.
Investigate Hardware demands of database redundancy technique.
Not necessary, because not within scope.

7. Scorecard (continued)
Attempt file transfer between Client and Server (hard coded, without GUI).
The preliminary connections module needs refinement before we can attempt a successful push.
This goal should be accomplished before the beginning of the spring semester.

8. Scorecard (continued)
Preliminary database tests simulating situations of high load.
To a small degree testing has started.
The goal is to test up to 20 clients at a time to guarantee adequate performance.

9. Additional Accomplishments
We have completed the Project Plan
A design Analysis has been created.
Preparations for a design draft are currently in the making.
After eating lots of Turkey, we are all super motivated to push forward.

10. Plans
We want to refine file transfer from a client to the server (database)
We want to stress test the server (database) using up to 20 simultaneous connections.
The GUI for the client will be further refined and integration of the communications module attempted.
Server to client file transfer to be attempted.
