Snapshot Creation

Snapshot Creation

Limitations

Using incremental or a series of 'delta' snapshots is not yet supported, tracking issue. There must be a single snapshot for a backfill.

Snapshot creation from the console

Create the initial Snapshot on the Source Cluster with the following commands:

console snapshot create

Depending on the size of the data on the source cluster and the bandwidth you've configured the cluster to provide for snapshots, this can take a while. You can tweak the maximum rate at which the source cluster's nodes will create the snapshot using the --max-snapshot-rate-mb-per-node option. The tradeoff here is that increasing the speed at which the snapshot is created also increases the amount of resources the nodes are devoting to that creation instead of serving normal traffic. If you don't specify a number for this, it will use the default for whatever version of source cluster you're using. See the docs for ES 7.10 here for more context.

You can get a point-in-time update on the snapshot status like so:

console snapshot status --deep-check

Example output a snapshot is completed
