Goal

Deploy a node using its node state snapshot.

Steps

Obtain snapshot via API request:

$ curl --request POST --url http://<node>/v1/producer/create_snapshot

Example:

$ curl --request POST --url http://127.0.0.1:8888/v1/producer/create_snapshot

Output

snaphot-<hash>.bin

The file generated is the node state snapshot. This file alone will not be enough to restore your node. You will also need two more blocklog files. These are blocks.index andblocks.log. Before restoring a node, these files must be in the same place where they were generated.

To deploy node using the node state snapshot, you need to specify path to the snapshot in command line:

$ nodeos --snapshot <snapshot-directory>/snapshot-<hash>.bin

Important

--snapshot is incompatible with --geneis-json and --genesis options as the snapshot contains genesis information.
