Name

       nix-store --dump-db - export Nix database

Synopsis

       nix-store --dump-db [paths…]

Description

       The  operation  --dump-db  writes a dump of the Nix database to standard output. It can be loaded into an
       empty Nix store using --load-db. This is useful for  making  backups  and  when  migrating  to  different
       database schemas.

       By default, --dump-db will dump the entire Nix database. When one or more store paths is passed, only the
       subset of the Nix database for those store paths is dumped. As with --export, the user is responsible for
       passing all the store paths for a closure. See --export for an example.
