### Manual setup of docker volumes from snapshots
For an example of copying and configuring permissions for a hub docker volume, see [this](https://github.com/lbryio/hub/blob/master/scripts/initialize_rocksdb_snapshot_dev.sh). For an example for the elasticsearch volume, see [this](https://github.com/lbryio/hub/blob/master/scripts/initialize_es_snapshot_dev.sh). **Read these scripts before running them** to avoid overwriting the wrong volume, they are more of a guide on how to set the permissions and where files go than setup scripts.
