Dumping all the sql statements as backup

I have some long running processes that do very long simulations which
at the end need to write things on a database.

At the moment sometimes there are network problems and we end up with
half the data on the database.

The half-data problem is probably solved easily with sessions and
sqlalchemy (a db-transaction), but still we would like to be able to
keep a backup SQL file in case something goes badly wrong and we want to
re-run it manually..

This might also be useful if we have to rollback the db for some reasons
to a previous day and we don't want to re-run the simulations..

Anyone did something similar?
It would be nice to do something like:

with CachedDatabase('backup.sql'):
    # do all your things
