SQL Server databases are vulnerable to corruption or damage or issues like Server crash, downtime due to maintenance, or other reasons. Since many business enterprises rely on the Microsoft SQL Server for data storage and records in bulk containing confidential and operational information associated with the organization, it is vital for businesses to practice regular, full database backups to ensure SQL data accessibility all the time. Sometimes, when the SQL Server is accessible again after downtime, the existing database needs to be replaced with a full database backup. That is what we will discuss in detail further in this blog.
