Usage: consul snapshot restore [options] FILE
|
|
|
|
Restores an atomic, point-in-time snapshot of the state of the Consul servers
|
|
which includes key/value entries, service catalog, prepared queries, sessions,
|
|
and ACLs.
|
|
|
|
Restores involve a potentially dangerous low-level Raft operation that is not
|
|
designed to handle server failures during a restore. This command is primarily
|
|
intended to be used when recovering from a disaster, restoring into a fresh
|
|
cluster of Consul servers.
|
|
|
|
If ACLs are enabled, a management token must be supplied in order to perform
|
|
snapshot operations.
|
|
|
|
To restore a snapshot from the file "backup.snap":
|
|
|
|
$ consul snapshot restore backup.snap
|
|
|
|
For a full list of options and examples, please see the Consul documentation.
