Sorry but what will I do? Will I copy everything under snapshot folder into under index folder? If I don't run backup command and just copy index folder anywhere else what is the difference between them (is it something like consistency for if any writing operation for segment files did not finished, or does backup command retrieves indexes data at RAM)
