etcdctl: Save a snapshot of the etcd keystore.
$ etcdctl snapshot save ${path-to-snapshot-db}
try on your machine
The given command is used to create a snapshot of an etcd cluster and save it at a specified path. Let's break it down:
etcdctl
: It is a command-line tool used to interact with an etcd cluster. etcd is a distributed key-value store that is often used for configuration and service discovery in distributed systems.snapshot save
: This is the specific command within etcdctl used to create a snapshot of the etcd cluster.${path-to-snapshot-db}
: This is a placeholder for the actual path where you want to save the snapshot database file. You need to replace it with the appropriate file path on your system.
To use this command, you would replace ${path-to-snapshot-db}
with the path where you want to save the snapshot. For example, if you want to save the snapshot file at the /var/lib/etcd/snapshot.db
path, the command would be:
etcdctl snapshot save /var/lib/etcd/snapshot.db
Executing this command would create a snapshot of the etcd cluster and save it as a database file at the specified path. The snapshot file contains the complete state of the etcd cluster at the time the snapshot was taken, including all key-value data and cluster metadata. It can be later used to restore the cluster to the same state if needed.

never run a command you are not sure if it is safe.
