If the only need you need is sync repos without exclusions or transformations I wouldn't bother, it could work for you until it doesn't when they archive it or kill it like kaniko or so many other google products/tools.

Gitlab has really simple way to mirror from Gitlab to Github or other git vendors/servers

I really doubt copybara ever gets killed. AFAIK it’s a pretty central tool to google3 and how they maintain and vendor OSS projects at scale

yea copybara is really for doing transforms in one or both directions.

E.g. translating from external bzl to internal blaze BUILD compatibility, changing between external imports and internal third_party style imports, etc etc.

If it's a pure mirror, copybara is super overkill
