Overview
The file system created by the snapshot has all the data in the snapshot, and the usage capacity of the file system is consistent with the data of the source file system at the current snapshot creation time.
Snapshot creation enables file systems to be replicated and shared across availability zones.
The file system created from the snapshot can freely select a file service protocol, which is not limited by the type of source file system protocol, and can also reselect a network.
Directions
- Log in to the CFS Console.
- On the snapshot list page, click Create File System in More Action to the right of the target snapshot.
- In the pop-up dialog box, set the following parameters:
| Field | Meaning |
|---|---|
| AZ | Select the availability zone for which you want to create a CFS file system. |
| Storage Class | Select the required storage type, general standard storage, or general performance storage. |
| File Service Protocol | Select the protocol type of file system, NFS or SMB. NFS protocol is more suitable for Linux/Unix Client, and CIFS/SMB protocol is more suitable for Windows Client. |
| Network Type | - VPC To share the file system with CVM under the virtual private cloud (VPC), you need to select the VPC when creating the file system. When the file system is a virtual private cloud, only CVM instances within the same virtual private cloud can be mounted if no special network settings are made. - If there is a need to share file systems across multiple networks, check Cross-network Access to the File System. |
| Permission Group | Each file system must be bound with a permission group, which specifies a set of accessible allowlist and lists the read and write permissions. |
| Tag | - If you already have a tag, you can add a tag for the new file system here; - If you do not already have a tag, go to the Tag Console and create the required Tag before binding it to the file system. Alternatively, you can add Tags to the file system after it has been created. |
- Click OK.
You can view the created file system on the File System List page. See Getting Started to mount the file system to a client in the same availability zone.
