The simple recovery model imposes the following restrictions on restore operations: File restore and piecemeal restore are available only for read-only secondary filegroups. For information about these restore scenarios, see File Restores (Simple Recovery Model) and Piecemeal Restores (SQL Server).
A complete database restore might involve simply restoring and recovering a full database backup. Alternatively, a complete database restore might involve restoring a full database backup followed by restoring and recovering a differential backup.

This is known as Fast Recovery. The restore operations that are available for a database depend on its recovery model. The following table summarizes whether and to what extent each of the recovery models supports a given restore scenario. Complete recovery (if the log is available).
A restore scenario in SQL Server is the process of restoring data from one or more backups and then recovering the database. The supported restore scenarios depend on the recovery model of the database and the edition of SQL Server.
Restores one or more files, without restoring the entire database. File restore can be performed while the database is offline or, for some editions of SQL Server, while the database remains online. During a file restore, the filegroups that contain the files that are being restored are always offline. Page restore.
Restoring and recovering files or pages, instead of the whole database, provides the following advantages: Restoring less data reduces the time required to copy and recover it. On SQL Server restoring files or pages might allow other data in the database to remain online during the restore operation.
To perform a database restore, the Database Engine executes three steps: Creates the database and transaction log files if they do not already exist. Copies all the data, log, and index pages from the backup media of a database to the database files. Applies the transaction log in what is known as the recovery process.
Regardless of the recovery model of a database, a SQL Server backup cannot be restored by a version of SQL Server that is older than the version that created the backup.
