Is there --copy-chunker-params equivalent when init a repo?

[zxcat]

Even though the copy command can transfer snapshots between arbitrary repositories, deduplication between snapshots from the source and destination repository may not work. Restic solves this with --copy-chunker-params when init repo.

How to do this in rustic?

Instead of pre-initializing the repos you want to copy snapshots into, just use rustic copy --init for the first run - this will set the correct chunker parameters.

Note that rustic currently refuses to copy to a repository with different chunker parameters - IMO the right way to implement this action would be to re-chunk the data contained in the snapshot (which is not yet implemented).

This took me forever to figure out, though it makes total sense in hindsight.

I think a prominent reference in the documentation would be helpful, as looking for "--copy-chunker-params" only pointed to the comparison page that says we don't need it anymore with rustic.

I was missing the --init part.

Thank you for rustic. It's a pleasure to use.

Thanks for the hint. I updated the comparison page.

Thank you! I'll keep that in mind and will do so the next time I find something to improve.
