What are the 3 recovery models in SQL Server
SQL Server has three different recovery models: Simple, Full, and Bulk-Logged. The recovery model setting determines what backup and restore options are available for a database, as well as how the database engine handles storing transaction log records in the transaction log.
What is the simple recovery model
The "Simple" recovery model is the most basic recovery model for SQL Server. Every transaction is still written to the transaction log, but once the transaction is complete and the data has been written to the data file the space that was used in the transaction log file is now re-usable by new transactions.
How many types of recovery models are there in SQL Server
Three recovery models
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.
What is full recovery model
Using a full recovery model means the database can be recovered all the way to the point of failure, assuming the tail of the log is backed up after the failure. Furthermore, all forms of recovery are supported under the full recovery model.
