Cold storage and file prefix

General Topics
1

I want to try cold storage at scaleway (sftp→s3[hot+cold]). After reading docs I expected to find a prefix in my files, but I think it isn’t:

Is this the normal filenames?

File .shardscontains;

{"default":[3,3],"maxNonShardedLength":20}

Cold storage is not supported:

Kopia does not currently support cloud storage that provides delayed access to your files – namely, archive storage such as Amazon Glacier Deep Archive. Do not try it; things will break.

cold != archive

    1. ‘hot’ storage is typically the most expensive to store, the least expensive to access, and has the highest redundancy;
    2. ‘cold’ storage is less expensive to store, more expensive to access, and sometimes has less redundancy than hot storage;
    3. and ‘archive’ storage is the least expensive to store, the most expensive to access, often has less redundancy than both hot and cold storage, and most of the time provides access to your files with a delay of several hours (i.e., you cannot instantly download your files).

I suspect prefix may be used with folder names and not with filenames; will the repostory be flatened when I copy it to s3?
