Yes. Resulting backup file about 3.8Mb

At the moment the problem does not seem to result in any data loss,
but any error after backup/restore is of great concern.

I will email you privately about this.

restoring everything else? Obviously there is still some order issues
with procedures but these are fairly easy to avoid.
