Any advantage to using B2 backend over its S3 compatible API?

Getting Help

My reason to prefer the S3 API is one of convenience/key management really - my aws CLI is already configured with a B2 profile, so using it would avoid needing to do something new with B2 env vars.

However, if the B2 backend is somehow optimised for B2 - i.e. behaviour or at least implementation is slightly different to be cheaper/faster/whatever - then it’s probably worth the bother.

Thanks in advance,

Ah, maybe it doesn’t matter anyway, as restic seems not to use boto/otherwise ignore existing AWS config.
