Is it possible that the database files changed while the backup was 
running, e.g. that something was committed to the SVN repository?

That might cause the above error. If so, then subsequent backups should 
work, as long as the database is not being modified during the backup.

In that case, it is probably better to make a hot copy of the subversion 
repository and back that up instead of the live repository.

If not, then please let me know if you can reproduce the error. Please 
could you try downloading and compiling my merge branch 
(http://bbdev.fluffy.co.uk/svn/box/chris/merge) and enabling the 
LogAllFileAccess option (LogAllFileAccess = yes in bbackupd.conf) and see 
what it outputs about the file concerned?

Cheers, Chris.
