Does Duplicacy support Glacier or GCS-Archive?

As per this article Gchen (Dup dev) wrote 3 years ago:

It has not been optimized for cold storages as of now, but in the future it will.
[Duplicacy caused me $122 USD of cloud storage cost (file operations) in just 1 month. Arq 6 cost $22 USD for 6 months. How to fix that?]

Has this been done?

I would be a happy Duplicacy-User, if it supports Glacier or GCS-Archive.

best regards

Glacier, or any other archival storage that requires thawing - no.

GCS-Archive — yes, as it behaves just like any other s3 storage. There is no thawing needed, data available immediately: The differences are on the retention and billing side.
