You can create backup of the databases.
But databases are build to taken care of multiple queries.
Let take a scenario where too jobs are created to update table values. In this case, database will allow first thread to write the database while other can only read the values.
So, it the in-built mechanism of the database that helps it to prevent it for damage.
But for the safety, you can regular backup the database by using some ETL tools or in-built backup option if database support it.
Hope this helps.
