  disk = '' with differential

Transactional Log / Log

 Backup log to disk = ''

For instance,: The following command helps backup the entire database (Full / Database) named TestDB to the address D: with the name of the backup copy is TestDB_Full.bak

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

The following command helps back up changes since the last backup on the database (Differential / Incremental) named TestDB to address D: with the name of the backup copy is TestDB_Full.bak

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

The following command helps back up the order of all transactions since the last transaction Log backup on the database (Transaction Log / Log) named TestDB to the address D: with the name of the backup copy is TestDB_Full.bak

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