Hi… LFSC is LiteFS Cloud, the managed backup service that Fly.io offered for a while but (unfortunately) shut down a year ago:

People who were looking for a replacement when using LiteFS with static leasing were recommend LiteStream a bit further down in that thread:

For Consul-based leasing, the bulk of the former LiteFS Cloud code was donated by Fly.io and converted into a standalone project and made available under the MIT License by a generous fellow user:

(You would create and manage your own backup server, in that scenario.)
