Vault: Backup and Restore
To restore a Vault instance from a snapshot, the snapshot restore command can be used. This command will upload the snapshot to Vault and restore it. This must happen while Vault is running and will result in a brief downtime.
To force the restore of a snapshot with different unseal keys
-force needs to be specified.
This might be the case if you’re restoring Vault to a new (empty) instance.
