Configure an Alibaba Cloud ECS instance as a transit node to migrate data from an external source to NAS.
Prerequisite
A file system is created. For more information, see Create a file system.
Use a new ECS instance as a transit node
Data transfer to and from a NAS file system consumes the public bandwidth of an ECS instance. To avoid impacting production services, purchase a dedicated ECS instance as a transit node.
The following limits apply when mounting a NAS file system during ECS instance creation:
Image: Automatic mounting is supported only on official Alibaba Cloud images.
To use a custom image from an ECS snapshot, manually mount the NAS file system after creating the ECS instance.
For Linux, see Mount an NFS file system.
For Windows, see Mount an SMB file system.
Mount directory: Only the root directory of a NAS file system can be mounted. Subdirectories are not supported.
Configure a new ECS instance as a transit node with the following recommended settings. For mount steps during purchase, see Mount a Alibaba Cloud NAS file system when you create an ECS instance.
Parameter | Recommendation |
Image |
|
Parameter | Recommendation |
Public IP Address | Select Assign Public IPv4 Address. |
Bandwidth Billing | Select Pay-By-Traffic. |

Use an existing ECS instance as a transit node
Mount the NAS file system on the existing ECS instance:
For Linux, see Mount an NFS file system.
For Windows, see Mount an SMB file system.
Next steps
After configuring the transit node, select a migration tool based on your requirements. For more information, see Migrate data to Alibaba Cloud NAS.
