This topic describes the operations that you must perform before you migrate data from a Network Attached Storage (NAS) file system to an Object Storage Service (OSS) bucket.
Additional considerations
If the Apsara File Storage NAS file system and the OSS bucket that you use in a migration job belong to different Alibaba Cloud accounts, we recommend that you log on to the Data Transport console with the account to which the NAS file system belongs.
Mount the NAS file system
- Mount an Apsara File Storage NAS file system
- You must mount your Apsara File Storage NAS file system on an Elastic Compute Service (ECS) instance. For more information, see Create a mount target.
- If you configure a permission group for the Apsara File Storage NAS file system, you must add all IP addresses in the virtual private cloud (VPC) in which the ECS instance is deployed to the authorized address list. For more information, see Manage a permission group.
- Mount a NAS file system that is not deployed on Alibaba Cloud
- You must connect your NAS server to an Alibaba Cloud VPC.
- To allow access to your NAS server over an Alibaba Cloud VPC, you can connect the NAS server to the VPC by using an Express Connect circuit. For information about how to deploy an Express Connect circuit, contact Alibaba Cloud Technical Support.
- You can also connect your NAS server to the VPC over a VPN network.
- If access to the NAS server is restricted, you must configure the access policy of the NAS server to allow access from all IP addresses in the VPC to which the NAS server is connected.
- You must connect your NAS server to an Alibaba Cloud VPC.
Create a destination OSS bucket
Create a destination bucket to store the migrated data. For more information, see Create buckets.
