This article shows several ways of how you can restore a SQL Server database backup. In particular, we will consider how to restore database
- using T-SQL commands
- using SQL Server Management Studio
- using One-Click Restore utility
- using SqlBackupAndFtp application
How to restore SQL Server database from backup using T-SQL Commands
RESTORE DATABASE command is the most basic and universal way to restore SQL Server backups since T-SQL commands work everywhere whether you type them in SQL Server Management Studio, execute via sqlcmd utility or run from your program. Let’s review what commands are used to restore three types of backup: full, differential and transaction log backups.
Restore Full SQL Server database backup
Full backups contain all information necessary to restore your database to the point in time when the backup process had finished. The backup will overwrite your database if such is exist or produce a new SQL Server database. Let’s your full backup is stored in D:Adventureworks_full.bak and you want to restore it to Adventureworks database. You need to execute the following commands:
RESTORE DATABASE Adventureworks FROM DISK = 'D:Adventureworks_full.bak'
If you are going to continue with restoring differential or transaction log backups after that, you need to add NORECOVERY option. This will leave the backup process in restoring state and allow you to restore extra differential or transaction log backups.
RESTORE DATABASE Adventureworks FROM DISK = 'D:Adventureworks_full.bak' WITH NORECOVERY
Restore Differential SQL Server database backup
Differential backups contain changes that took place in the database since the last full backup. The last differential backup accumulates all the changes so you don’t need all previous differential backups to restore a database, just the last one. Before restoring the differential backup and need to restore the last full backup first with NORECOVERY option and then the last differential backup with RECOVERY option:
RESTORE DATABASE Adventureworks FROM DISK = 'D:Adventureworks_full.bak' WITH NORECOVERY GO RESTORE DATABASE Adventureworks FROM DISK = 'D:AdventureWorks_diff.dif' WITH RECOVERY GO
Restore Transaction Log SQL Server database backup
Transaction log backups contain all transactions that took place between the last transaction log backup (or the first full backup) and the moment when the backup process had finished. You have to restore all transaction log backups made after the last differential backup in the same sequence they were made. And, obviously, log backups are restored after you’re done with full and differential backups (Read more about Point-in-time recovery):
RESTORE DATABASE Adventureworks FROM DISK = 'D:Adventureworks_full.bak' WITH NORECOVERY GO RESTORE DATABASE Adventureworks FROM DISK = 'D:AdventureWorks_diff.dif' WITH NORECOVERY GO RESTORE LOG Adventureworks FROM DISK = 'D:Adventureworks_log1.trn' WITH NORECOVERY GO RESTORE LOG Adventureworks FROM DISK = 'D:Adventureworks_log2.trn' WITH RECOVERY GO
How to restore database from backup using SQL Server Managment Studio
If you have SQL Server Management Studio installed, you can restore database backup using its interface alone. Just follow the instructions:
1. Connect to your SQL Server and right-click on the “Databases” directory and choose “Restore Database”
2. Click the button beneath the “Source” section next to “Device”
3. In the “Select backup device” press “Add”
4. Select the backup file or files (.bak) you are going to restore, then click “OK”
5. In the “Restore Database” window specify the database’s name you will restore and click “OK” to start
How to restore database from backup using One-Click Restore
If you want to quickly restore SQL database from backup (full backup), then you can take advantage of a simple utility called One-Click Restore. All you need to do is to select a .bak or .zip backup file and select a database where you want to restore it.
How to restore SQL Server database using SqlBackupAndFtp
If you use SqlBackupAndFtp to create SQL Server backups then you can restore them right from the history pane:
To restore on the same server where the backups were taken, in the History & restore section of SQLBackupAndFTP select the backup you want to restore, click the dots button on that line, select “Restore from Backup…” and follow the steps.
The good thing here is that you can choose any backup of any type (full, differential or log) and all other necessary backups will be restored automatically.
