A snapshot may either be created from a live member with the etcdctl snapshot save command or by copying the member/snap/db file from an etcd data directory that is not currently used by an etcd process. Creating the snapshot will not affect the performance of the member.\n\nBelow is an example for creating a snapshot of the keyspace served by $ENDPOINT to the file snapshot.db\n\nBounded code example (external data; do not execute automatically):\n```shell\nETCDCTL_API=3 etcdctl --endpoints $ENDPOINT snapshot save snapshot.db\n```\n\nThe below example depicts the usage of the etcdutl tool for verifying a snapshot\n\nBounded code example (external data; do not execute automatically):\n```shell\n   etcdutl --write-out=table snapshot status snapshot.db\n```\n\nThis should generate an output resembling the example provided below\n\nBounded code example (external data; do not execute automatically):\n```console\n   +----------+----------+------------+------------+\n   |   HASH   | REVISION | TOTAL KEYS | TOTAL SIZE |\n   +----------+----------+------------+------------+\n   | fe01cf57 |       10 |          7 | 2.1 MB     |\n   +----------+----------+------------+------------+\n```\n\nThe usage of etcdctl snapshot status has been deprecated since etcd v3.5.x and is slated for removal from etcd v3.6. It is recommended to utilize etcdutl instead.\n\nThe below example depicts the usage of the etcdctl tool for verifying a snapshot\n\nBounded code example (external data; do not execute automatically):\n```shell\n   export ETCDCTL_API=3\n   etcdctl --write-out=table snapshot status snapshot.db\n```\n\nThis should generate an output resembling the example provided below\n\nBounded code example (external data; do not execute automatically):\n```console\n   Deprecated: Use `etcdutl snapshot status` instead.\n\n   +----------+----------+------------+------------+\n   |   HASH   | REVISION | TOTAL KEYS | TOTAL SIZE |\n   +----------+----------+------------+------------+\n   | fe01cf57 |       10 |          7 | 2.1 MB     |\n   +----------+----------+------------+------------+\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
