Method for uploading and downloading files to Alibaba Cloud OSS using the ossutil tool

Alibaba Cloud OSS cloud storage service can help individual and enterprise users store resources. Compared to using one's own server for storage, it offers higher stability, faster speed, greater efficiency, and is even cheaper. It is very suitable for websites that need to provide downloads or display a large number of files externally. Besides normal cloud storage usage, we can also utilize OSS for website backups or temporary resource forwarding. Today, while migrating a client's server, Naiba used this service and took the opportunity to document how to use the ossutil tool to upload files to OSS and then how to download files from OSS on the new server.Use Case:

• Server A, configuration: 1 core, 1GB RAM, 5Mbps bandwidth
• Server B, configuration: 2 cores, 8GB RAM, 6Mbps bandwidth
• The compressed website data on Server A is 4GB in size, with a maximum download speed of 600KB/s. Moving data from A to B would be very slow.

Therefore, Naiba used OSS as an intermediate network drive for temporary data storage. (A and B are not in the same region, or perhaps firewall rules were not opened, and the client did not provide the Alibaba Cloud admin account, so internal network transfer was not possible.)Solution:Purchase anAlibaba Cloud OSS service(discount package: 6 RMB for 6 months), then use the ossutil tool on both servers A and B to upload and download the website backup data.
