Frequently Asked Questions

Why is IRSA failing with some AWS SDKs in containers?

Some older or third-party AWS SDKs don't properly handle Web Identity Token credentials used by IRSA. Ensure the SDK version is >=1.12.262 (Java), boto3>=1.16.35, or use AWS SDKs with explicit web identity token support.

How can I avoid monolithic WebDAV uploads in backups?

Use backup tools that support chunked uploads (e.g., Rclone, Restic, or Duplicacy). These split large archives into smaller pieces, enabling resumable transfers and better error handling.

Is .NET Aspire production-ready for enterprise use?

Yes, .NET Aspire entered GA in 2024 and is designed for enterprise cloud-native development, especially within Azure. However, tight coupling to Microsoft tooling may limit multi-cloud flexibility.
