How to recover full data after flush data

unfortunately, we flush data from couchbase admin portal and we want to recover all data. can you please assist us, how to recover all the data.

On solid state storage: Deleted is effectively gone. On spinning disk: If you did a full format, the data is effectively gone. If you did a quick format or just deleted the file data may still be there, just marked as “deleted”. Directly reading the drive data with software can often recover files.stories

Overwriting with a pass of any other data - 1s, 0s, random, whatever - effectively destroys data beyond reasonable recovery.
