Backup is a copy of data/database, etc. Backing up MS SQL Server database is essential for protecting data. MS SQL Server backups are mainly three types − Full or Database, Differential or Incremental, and Transactional Log or Log.

Method 1 – Using T-SQL

Full Type

Backup database <Your database name> to disk = '<Backup file location + file name>'

Differential Type

Backup database <Your database name> to 
   disk = '<Backup file location + file name>' with differential

Log Type

Backup log <Your database name> to disk = '<Backup file location + file name>'

Example

The following command is used for full backup database called 'TestDB' to the location 'D:\' with backup file name 'TestDB_Full.bak'

Backup database TestDB to disk = 'D:\TestDB_Full.bak'

The following command is used for differential backup database called 'TestDB' to the location 'D:\' with backup file name 'TestDB_diff.bak'

Backup database TestDB to disk = 'D:\TestDB_diff.bak' with differential

The following command is used for Log backup database called 'TestDB' to the location 'D:\' with backup file name 'TestDB_log.trn'

Backup log TestDB to disk = 'D:\TestDB_log.trn'
