I'm using protocol2.
This is my test:
1- Run a backup of only one file with 1GB size.
2- I kill the client at 90% (900MB is upload, and i can see the size of 
the globale/data directory at 900MB).
3- Wait 2h, and run a backup again
4- 1GB is upload again to the server, and i can see the size of the 
globale/data directory at 1900MB.

Is it a bug ? How can i check ?

Thanks.
