mysql DB backup insert update

[omidMolaverdi]

Before I start, thanks for the great package.

I use laravel-backup for daily backups and recently noticed that the db backup requires deleting a whole table before being restored. Is there any way that the backup applies something like ON DUPLICATE KEY UPDATE on records and also if the table already existed then just updates the table? So my question is highlighted below:

• if a table already existed then just update the table
• if a record already existed then update otherwise insert

Thanks.
