To back up your cluster's data, you can use the <<modules-snapshots,snapshot API>>.
|
|
|
|
include::../snapshot-restore/index.asciidoc[tag=snapshot-intro]
|
|
|
|
[TIP]
|
|
====
|
|
If your cluster has {es} {security-features} enabled, when you back up your data
|
|
the snapshot API call must be authorized.
|
|
|
|
The `snapshot_user` role is a reserved role that can be assigned to the user
|
|
who is calling the snapshot endpoint. This is the only role necessary if all the user
|
|
does is periodic snapshots as part of the backup procedure. This role includes
|
|
the privileges to list all the existing snapshots (of any repository) as
|
|
well as list and view settings of all indices, including the `.security` index.
|
|
It does *not* grant privileges to create repositories, restore snapshots, or
|
|
search within indices. Hence, the user can view and snapshot all indices, but cannot
|
|
access or modify any data.
|
|
|
|
For more information, see <<security-privileges>>
|
|
and <<built-in-roles>>.
