You need to choose a backup solution. Which solution should you choose?

SharePoint Central Administration includes a built-in backup and restore interface that captures all SharePoint-specific configuration, content databases, and service applications as a coordinated unit. This ensures consistency across all SharePoint components and preserves SharePoint metadata that raw SQL or OS-level backups may not fully capture. It is the native, supported method for SharePoint farm-level backup.

SQL Server Management Studio backups only capture the raw database files and do not account for SharePoint-specific configurations, service application settings, or the relationships between databases that Central Administration backup preserves.

Windows Server Backup can back up volumes and files but is not SharePoint-aware and cannot perform a coordinated, consistent backup of a SharePoint farm's distributed components and databases.

While DPM is a valid enterprise backup tool that supports SharePoint, in the context of this question the simpler and directly supported native option is Central Administration, which is the recommended baseline approach.
