`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.
