What is recovery model?
SQL Server backup and restore operations occur within the context of the recovery model of the database. Recovery models are designed to control transaction log maintenance. A recovery model is a database property that controls how transactions are logged, whether the transaction log requires (and allows) backing up, and what kinds of restore operations are available. Three recovery models exist: simple, full, and bulk-logged. Typically, a database uses the full recovery model or simple recovery model. A database can be switched to another recovery model at any time.

How can one develop a database disaster recovery strategy?
In order to develop a database disaster recovery strategy one must first discover what it is that is absolutely essential and cannot be lost.

What are the components of dba?
The components of a Database Administrator (DBA) role typically include managing databases, ensuring data security and integrity, optimizing database performance, implementing backup and recovery procedures, and overseeing database design and structure. DBAs are responsible for troubleshooting issues, monitoring database activity, and implementing database upgrades or migrations. They may also work with developers, analysts, and other stakeholders to ensure that database systems meet business requirements.
Why can a failure in a database environment be more serious than one in a non-database environment?
Database failures for Production envionments could be downtime for the database (data cannot be retrieved or uploaded) or a data loss in which a recovery needs to be performed, which also equates to downtime until the data is recovered. Businesses equate downtime to $$$ loss. It is a database administrator's job to ensure the database is designed for minimal downtime--the recovery is measured in "MTR" (meantime to recovery). What's the fastest way the data can be restored? A full recovery? A point in time? (roll the data up right before the data loss occurred). This must be done carefully through communcation with the individuals where the data loss occurred. If the DBA is given the wrong time and the data is rolled forward beyond the corruption point, then the recovery must be started again. There is much more to this subject.......based on each company's database, design, data, etc.
