Sorry if I'm reposting but I didn't find a response yet on how to restore from a backup on S3.
I have a 3 zk nodes ensemble I'm using S3 config and S3 backup.
I read that exhibitor builds a Lucene index of the transactions and allows you to search for a specific transaction and replay it and this works great when using the UI I click on New-index, the index gets generated and I can reply the transactions (the index does seem generated only when I use the UI not automatically by default is it normal?).
What about the files I see uploaded in my s3 bucket? How I restore them if the whole cluster gets deleted?

Backups are periodically done according settings in Config tab:

I don't think we currently support restoring transactions without using Exhibitor.
Although I think its possible for you may to parse the S3 files and write to Zookeeper yourself (PRs welcome!).

Hello. Why does Exhibitor explicitly provide storing backups to S3 if it does not have any feature to use these file to restore from those back-ups? I am curious about what the developer using Exhibitor was expected to do with the S3 backups they created via Exhibitor?
