This topic describes how to migrate data from a NAS file system to another storage medium or from another storage medium to a NAS file system.
Migrate data from an on-premises storage system to NAS
Migrate data between a NAS file system and an OSS bucket
- Use the ossutil tool of OSS. The ossutil tool has the following benefits:
- Provides a wide range of simple and convenient commands to manage objects and buckets and ensures high performance of operations.
- Supports concurrent upload and resumable upload of files.
- Allows you to upload and download directories or folders.
For more information, see Migrate data by using ossutil.
- Use Data Transport.
Data Transport is a tunnel between different storage services of Alibaba Cloud. Data Transport allows you to migrate data between OSS and NAS without the need to deploy a migration tool. For more information, see Migrate data by using Data Transport.
Data Transport is in public preview. To migrate data by using Data Transport, submit a ticket to apply for a whitelist.
Migrate data between NAS file systems
We recommend that you use the following methods to migrate data between NAS file systems:
- If you use a Network File System (NFS) file system, we recommend that you use the rsync tool to migrate data. The rsync tool has the following benefits:
- After a file is uploaded or downloaded, the metadata of the file remains unchanged, including the owner and permission information.
- Incremental data can be synchronized.
- If you use a Server Message Block (SMB) file system, we recommend that you use the Robocopy tool of Windows to migrate data. The Robocopy tool supports features such as multi-thread concurrent migration and resumable upload. You can use scripts to accelerate data migration. For more information, see Migrate data by using the Robocopy tool.
- You can use Data Transport to migrate data. For more information, see Migrate data by using Data Transport.
