Hey @lbj2004032! Do I understand it correctly that you have deleted the .lotusminer folder? And wondering if it´s possible to recover it without a backup?

How to do it

[rjan90]

Hey! To fully recover a storage provider you will need backup.cbor with the storage providers metadata, and ideally the config.toml, and storage.json files.

That said, if you are missing the backup.cbor file you should still be able to initialize your storage provider as long as you have access to its actor/owner/adresses/etc and be able to prove the sectors you have on-chain until they expire. But everything that needs the metadata to function will cause issues. You can try to recover it using: lotus-miner init --no-local-storage --actor=xxx--sector-size=xxGiB --owner=xxx --worker=xxx
