RESTORE WITH NORECOVERY
You possibly can choose the WITH NORECOVERY possibility while you wish to proceed restoring further backup information, like transactional or differential. It modifications the database to restoring state till it’s recovered.
Now, let’s learn to use the WITH RECOVERY and NORECOVERY choices when restoring the database.
How one can Restore MS SQL Server Database with the RECOVERY Possibility?
You should use the WITH RECOVERY possibility to revive a database from full backup. It’s the default possibility within the Restore Database window and is used when restoring the final backup or solely the backup in a restore sequence. You possibly can restore database WITH RECOVERY possibility by utilizing SQL Server Administration Studio (SSMS) or T-SQL instructions.
1. Restore Database with RECOVERY Possibility utilizing SSMS

How one can Restore MS SQL Server Database with NORECOVERY Possibility?
You should use the NORECOVERY possibility to revive a number of backup information. For instance, in case your system fails and that you must restore the SQL Server database to the purpose simply earlier than the failure occurred, you then want a multi-step restore.

This selection modifications the state of the database to RESTORING and makes the database inaccessible to the customers except further backups are restored. You possibly can restore the database with the NORECOVERY possibility by utilizing SSMS or T-SQL instructions.
1. Utilizing T-SQL Instructions
Listed below are the steps to revive MS SQL database with the NORECOVERY possibility by utilizing T-SQL instructions:
Step 1: First, that you must restore the Full Backup by utilizing the under command:
RESTORE DATABASE [YourDatabaseName]
FROM DISK = N'C:PathToYourFullBackup.bak'
WITH NORECOVERY,
STATS = 10;
Step 2: Then, that you must restore the Differential Backup. Use the under command:
RESTORE DATABASE [YourDatabaseName]
FROM DISK = N'C:PathToYourDifferentialBackup.bak'
WITH NORECOVERY,
STATS = 10;
