Amazon AWS Glacier multi-part upload with CLI

Question

I've been struggling to find a simple way to backup my files using AWS Glacier. The documentation is not very explicit:

Doc 2

Anyone around here has some experience with AWS Glacier?

aws s3 sync my-local-folder s3://my-glacier-backup-bucket --storage-class GLACIER
