Amazon Glacier Upload Archive from In-Memory Data

See more Amazon Glacier Examples

Demonstrates how to add an archive to a vault from data in memory.

Note: This example requires Chilkat v9.5.0.78 or greater.

# See Global Unlock Sample for sample code.

# --------------------------------------------------------------------------
# Note: The above REST connection and setup of the AWS credentials
# can be done once.  After connecting, any number of REST calls can be made.
# The "auto reconnect" property passed to rest.Connect indicates that if
# the connection is lost, a REST method call will automatically reconnect
# if needed.
