The following are a few limitations to consider while using IONOS S3 Object Storage:
  • Access Keys: A user can have up to five access keys.
  • Storage size: The minimum storage size available is 1 Byte of data and is extendable to a maximum storage of petabytes.
  • Bucket count: A user can create a maximum of 500 buckets only.
  • Object size: The maximum allowed object size is 46.566 GB.
  • File upload size: A file upload size cannot exceed 4,65 GB. If you have a single file exceeding this limit, you can bypass it using multi-part uploads. CLI tools such as AWS CLI and graphical tools such as Cyberduck automatically handle larger files by breaking them into parts during uploading.
  • Bucket naming conventions: Only buckets for static website hosting can use dots (.) in the bucket names. For more information, see bucket Naming conventions.
  • Object name length: The maximum allowed length of the folder path, including the file name, is 1024 characters.
  • Bandwidth: Each connection is theoretically capped at approximately 10 G per region. However, remember that this is a shared environment. Based on our operational data, achieving peak loads up to 2x7 G is feasible by leveraging parallel connections, although this is on a best-effort basis and without any guaranteed Service Level Agreement (SLA).
