I want have a setup of multiple fluentbit that forward to a single fluentd (or two).

The HA architecture of fluentd is clear, but is it applicable with fluentbit=>fluentd architecture?

Fluentd have file based buffering with retries that can configured to days or weeks in case that the target inresponssive for a long timeto avoid loosing records. Can we have file based buffering and retry for such a long time with fluentbit?

As of now, the FluentBit cannot be set up in HA mode exactly like FluentD. As mentioned here

the only HA mode supported is in-memory buffering, meaning: if the logs cannot be shipped to the destination there is a retry logic in place.

If you refer to HA where having primary and secondary destinations as well with balancing support that feature has not been implemented yet.

From another bug description it seems like if you configure two IP addresses behind a hostname which is used in the fluentbit configuration, you might be able to achieve HA. Based on your context, YMMV
