backup

I'm reading about Red Gate SQL Backup, and I liked the concept of creating a database backup compressed and writing on disk the compressed backup directly without an intermediate SQL Server native backup.

And I'm wondering how this type of software make backups. It accesses the database files directly? It uses some sort of SQL Server or Windows API? Windows Shadow Copy?
