Notes:

(1) Supports streaming.

(2) Max. single upload size is limited by the nodes to a default 100MB for performance reasons. If you need higher limits for whatever reason, please contact Flashback Support. For uploads >100MB, use the resumable uploads APIs.

(3) The following restrictions apply:

• The copy operation follows all the restrictions imposed by the destination storage in terms of region, storage class, permissions, file size, etc.

• Check out in S3 docs, GCS docs and Azure Blob docs for more detail on platform specific conditions and constraints.

• The source bucket must be part of the Flashback Repository whose API keys you are using. The destination bucket does not have to be part of the Repository, but it must be accessible using the same credentials provided for the destination bucket.
