# Examples
|
||
|
|
|
||
|
|
* Copy Firefox from the local store to a binary cache in `/tmp/cache`:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy --to file:///tmp/cache $(type -p firefox)
|
||
|
|
```
|
||
|
|
|
||
|
|
Note the `file://` - without this, the destination is a chroot
|
||
|
|
store, not a binary cache.
|
||
|
|
|
||
|
|
* Copy the entire current NixOS system closure to another machine via
|
||
|
|
SSH:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy -s --to ssh://server /run/current-system
|
||
|
|
```
|
||
|
|
|
||
|
|
The `-s` flag causes the remote machine to try to substitute missing
|
||
|
|
store paths, which may be faster if the link between the local and
|
||
|
|
remote machines is slower than the link between the remote machine
|
||
|
|
and its substituters (e.g. `https://cache.nixos.org`).
|
||
|
|
|
||
|
|
* Copy a closure from another machine via SSH:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy --from ssh://server /nix/store/a6cnl93nk1wxnq84brbbwr6hxw9gp2w9-blender-2.79-rc2
|
||
|
|
```
|
||
|
|
|
||
|
|
* Copy Hello to a binary cache in an Amazon S3 bucket:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy --to s3://my-bucket?region=eu-west-1 nixpkgs#hello
|
||
|
|
```
|
||
|
|
|
||
|
|
or to an S3-compatible storage system:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy --to s3://my-bucket?region=eu-west-1&endpoint=example.com nixpkgs#hello
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that this only works if Nix is built with AWS support.
|
||
|
|
|
||
|
|
* Copy a closure from `/nix/store` to the chroot store `/tmp/nix/nix/store`:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# nix copy --to /tmp/nix nixpkgs#hello --no-check-sigs
|
||
|
|
```
|
||
|
|
|
||
|
|
# Description
|
||
|
|
|
||
|
|
`nix copy` copies store path closures between two Nix stores. The
|
||
|
|
source store is specified using `--from` and the destination using
|
||
|
|
`--to`. If one of these is omitted, it defaults to the local store.
