-== Manage the snapshot lifecycle
-
-You can set up snapshot lifecycle policies to automate the timing, frequency, and retention of snapshots.
-Snapshot policies can apply to multiple data streams and indices.
-
-The snapshot lifecycle management (SLM) <<snapshot-lifecycle-management-api, CRUD APIs>> provide
-the building blocks for the snapshot policy features that are part of the Management application in {kib}.
-The Snapshot and Restore UI makes it easy to set up policies, register snapshot repositories,
-view and manage snapshots, and restore data streams or indices.
-
-You can stop and restart SLM to temporarily pause automatic backups while performing
-upgrades or other maintenance.

-=== Security and SLM
-
-Two built-in cluster privileges control access to the SLM actions when
-{es} {security-features} are enabled:
-
-`manage_slm`:: Allows a user to perform all SLM actions, including creating and updating policies
-and starting and stopping SLM.
-
-`read_slm`:: Allows a user to perform all read-only SLM actions,
-such as getting policies and checking the SLM status.
-
-`cluster:admin/snapshot/*`:: Allows a user to take and delete snapshots of any
-index, whether or not they have access to that index.
-
-For example, the following request configures an `slm-admin` role that grants the privileges
-necessary for administering SLM.
-
-[source,console]
------------------------------------
-POST /_security/role/slm-admin
-{
-  "cluster": ["manage_slm", "cluster:admin/snapshot/*"],
-  "indices": [
-    {
-      "names": [".slm-history-*"],
-      "privileges": ["all"]
-    }
-  ]
-}
------------------------------------
-// TEST[skip:security is not enabled here]
-
-Or, for a read-only role that can retrieve policies (but not update, execute, or
-delete them), as well as only view the history index:
-
-[source,console]
------------------------------------
-POST /_security/role/slm-read-only
-{
-  "cluster": ["read_slm"],
-  "indices": [
-    {
-      "names": [".slm-history-*"],
-      "privileges": ["read"]
-    }
-  ]
