That’s why a good disaster recovery plan is important

A SQL Server disaster recovery plan (DRP) is a process to have SQL Server up and running, and to overcome data loss after a disaster. A disaster recovery plan must be planned and documented in order to prevent catastrophic data loss and incidents.

You can capture and save data about each event to a file or table to analyze later.

For example you can monitor a production environment to see which stored procedures are affecting performance by executing too slowly.

Each step contains its own task, for example, backing up a database. if you want to back up all the company servers every weekday after hours, you can automate this task.
