Warning: Restored data contract can not be connected if contract address not provided. Contract address of backup should noted and used to correctly connect.

In order to restore backup file, container should be ran with paramter restore and FILENAME.

docker-compose run --rm parity1 restore 2018-11-20.tar.gz will download data S3 and restore to the parity1 volume. This should be repeated for all the parity node connected.

$ docker-compose build parity1 parity2 parity3
$ docker-compose run --rm parity1 restore <FILENAME>
$ docker-compose run --rm parity2 restore <FILENAME>
$ docker-compose run --rm parity3 restore <FILENAME>

$ docker-compose up

While restoring it is possible that volume data conflicts in which case volumes for parity should be deleted.

Warning: This will replace data.

$ docker-compose down -v
