An organization should always have a plan for any possible downtime, known as disaster recovery. It helps when you know exactly what to do in an emergency. For example, if you deleted data accidentally, what would you do? What is the best way to minimize downtime so that you can recover the database without losing data?
Practice makes perfect, and backup drills are an excellent way to ensure that everyone involved knows what their role is if an emergency happens. Backing up is only helpful if you’ve adequately tested restoring the original data, so regularly doing restoration tests will ensure that no time or effort goes wasted should your database be deleted or corrupted!
SQL Server provides you with multiple ways to take the database backups - by writing T-SQL statements or creating an SSIS package. Alternatively, you can leverage PowerShell modules for automating tasks such as database backups.
SQL Server has a diverse range of PowerShell commands for managing SQL Server tasks, and DBATools is a helpful repository for these commands, which contain more than 500 different actions to do things like backup/restore, monitoring, administration tasks with simple to use commands.
