# Synthetic File System

## **Synthetic File System**

A synthetic file system allows us to store and use incremental backups as if they were full backup files, but they take up a fraction of full file size.

To start using Synthetic File System read **Prerequisites** for two supported scenarios:

Synthetic filesystem [**XFS/NFS 4.2**](https://docs.storware.eu/backup-and-recovery-71/deployment/backup-destinations/filesystem/synthetic-file-system/synthetic-xfs)

Synthetic filesystem [**DD Boost**](https://docs.storware.eu/backup-and-recovery-71/deployment/backup-destinations/filesystem/synthetic-file-system/synthetic-ddboost)
