[Box Backup] Error (4/11) with 4GB Files

I think this may be related to a bug that I recently fixed, where bbackupd 
would choose an invalid block size (greater than the maximum allowed) for 
files over 2 GB.

Please could you try using my chris/merge branch (svn checkout 
http://bbdev.fluffy.co.uk/svn/box/chris/merge/) and see if it solves this 
problem?

Unfortunately, because the file on the store is not valid, you will have 
to upload it again, possibly by renaming those files while bbackupd is not 
running.

Do you happen to know if subsequent (incremental) backups of those same 
files work?

> When I run a "bbackquery -qa compare" I get these ERRORs:
>
> ERROR:  (4/11) during file fetch and comparsion for '/dlb5/home/bak/ARCHIVE+'
> ERROR:  (7/42) during file fetch and comparsion for 
> ERROR:  '/dlb5/home/bak/ARCHIVE++'
> ERROR:  (7/42) during file fetch and comparsion for 
> ERROR:  '/dlb5/home/bak/ARCHIVE+++'

This should hopefully be fixed in chris/merge as well (after the files 
have been re-uploaded).

Cheers, Chris.
