8.8. Best practices for using S3 in Acronis Cyber Infrastructure¶

8.8.1. S3 bucket and key naming policies¶

It is recommended to use bucket names that comply with DNS naming conventions:

• Can be from 3 to 63 characters long
• Must start and end with a lowercase letter or number
• Can contain lowercase letters, numbers, periods (.), hyphens (-), and underscores (_)
• Can be a series of valid name parts (described previously) separated by periods

An object key can be a string of any UTF-8 encoded characters, up to 1024 bytes long.

8.8.2. Improving performance of PUT operations¶

Object storage supports uploading objects as large as 5 GB per single PUT request (5 TB via multipart upload). Upload performance can be improved by splitting large objects into pieces and uploading them concurrently (thus dividing the load between multiple OS services) with the multipart upload API.

It is recommended to use multipart uploads for objects larger than 5 MB.
