            text_mode=True,
            overwrite=True,
            with_atomicwrite=True,
            with_lockfile=True,
            with_exclusive=False, # unable work with `with_atomicwrite`

Restore data from crash

Make sure set with_backup=True and backup_for_fault=True:

with open_for_write(path, with_backup=True, backup_for_fault=True) as fp:
    ...

Then you can restore it from the backup:

try_rollback(path)
