# Name
`nix-store --export` - export store paths to a Nix Archive
## Synopsis
`nix-store` `--export` *paths…*
## Description
The operation `--export` writes a serialisation of the specified store
paths to standard output in a format that can be imported into another
Nix store with `nix-store --import`. This is like `nix-store
--dump`, except that the NAR archive produced by that command doesn’t
contain the necessary meta-information to allow it to be imported into
another Nix store (namely, the set of references of the path).
This command does not produce a *closure* of the specified paths, so if
a store path references other store paths that are missing in the target
Nix store, the import will fail.
{{#include ./opt-common.md}}
{{#include ../opt-common.md}}
{{#include ../env-common.md}}
# Examples
To copy a whole closure, do something
like:
```console
$ nix-store --export $(nix-store -qR paths) > out
```
To import the whole closure again, run:
```console
$ nix-store --import < out
```
