Functions
Table 1 lists common SFS functions.
Before using SFS, you are advised to learn basic concepts such as NFS and CIFS in SFS Basic Concepts to better understand the functions provided by SFS.
- √: indicates that the file system type supports this function.

SFS Capacity-Oriented |
SFS Turbo |
General Purpose File System |
---|---|---|---|---|
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 multiple ECSs, mount the file system to implement file sharing between ECSs. The NFS protocol is recommended for Linux clients. |
√ |
√ |
√ |
|
Common Internet File System (CIFS) is a protocol used for network file access. Using the CIFS protocol, network files can be shared between hosts running Windows. The CIFS protocol is recommended for Windows clients. |

|
Multiple VPCs can be configured for a file system so that ECSs belonging to different VPCs can share the same file system, as long as the VPCs that the ECSs belong to are added to the VPC list of the file system or the ECSs are added to the authorized addresses of the VPCs. |
√ |
√ Implemented through VPC peering connection |
√ |
|
If VPC IDs used by other accounts are added to the VPC list of a file system and IP addresses or IP address ranges of ECSs are added to the authorized address list, ECSs of different VPCs and of different accounts can share the same file system. |

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. |

SFS enables you to encrypt data on the new file systems as required. |

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 to ensure smooth running of services. |

Cloud Trace Service (CTS) records operations of SFS resources, facilitating query, audit, and backtracking. |

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. If there are more than 20 enterprise projects, SFS Turbo is recommended. |

Tag |
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. |
