Functions

Table 1 lists common SFS Turbo functions.

Before using SFS Turbo, you are advised to learn basic concepts such as NFS and CIFS in SFS Turbo Basic Concepts to better understand the functions provided by SFS Turbo.

**Table 1** Common SFS Turbo functions
Function	Description	Region Availability
NFS	Network File System (NFS) is a distributed file system protocol that allows different computers and OSs to share data over a network. After the NFS client is installed on each ECS, you can mount the file system to implement file sharing between ECSs. NFS is recommended for Linux clients.	All
File system management	File systems are containers that store files in SFS Turbo. You can create, view, and delete SFS Turbo file systems.	All
Permissions	SFS Turbo uses Identify and Access Management (IAM) for permissions management. You can control the read and write permissions of file systems by granting IAM users fine-grained SFS Turbo permissions using IAM custom policies.	All
SFS Turbo file system backup	A backup is a complete copy of a file system at a specific time and it records all configuration data and service data at that time. If your file system is faulty or a logical error occurs in the data in the file system, you can use the backup data to restore the data quickly.	All
SFS Turbo file system encryption	You can encrypt data on the newly created file systems if needed.	All
SFS Turbo file system capacity expansion	You can expand the capacity of a file system if needed.	All
SFS Turbo file system monitoring using Cloud Eye	Cloud Eye is a multi-dimensional resource monitoring service. With Cloud Eye, you can view the file system usage and service running status, and respond to exceptions in a timely manner.	All
SFS Turbo file system auditing using CTS	Cloud Trace Service (CTS) records operations performed on SFS Turbo file systems, facilitating query, audit, and backtracking.	All
Enterprise project	An enterprise project manages multiple resource instances by category. Resources and projects in different cloud service regions can be classified into one enterprise project. An enterprise allows you to classify resources based on departments or project groups and put relevant resources into the same enterprise project for management. Resources can be migrated between enterprise projects.	All
File system tagging	You can use tags to classify and identify file systems. If you add tags to a file system, service detail records (SDRs) generated for it will be labeled with these tags. You can classify SDRs by tag for cost analysis.	All
