= {ilm-init}: Manage the index lifecycle

[partintro]
--
You can configure {ilm} ({ilm-init}) policies to automatically manage indices according to
your performance, resiliency, and retention requirements. 
For example, you could use {ilm-init} to:

* Spin up a new index when an index reaches a certain size or number of documents
* Create a new index each day, week, or month and archive previous ones
* Delete stale indices to enforce data retention standards

[TIP]
To automatically back up your indices and manage snapshots, 
use <<getting-started-snapshot-lifecycle-management,snapshot lifecycle policies>>.

* <<overview-index-lifecycle-management>>
* <<ilm-concepts>>
* <<getting-started-index-lifecycle-management>>
* <<ilm-actions>>
* <<set-up-lifecycle-policy>>
* <<index-lifecycle-error-handling>>
* <<start-stop-ilm>>
* <<ilm-configure-rollover>>
* <<ilm-with-existing-indices>>
* <<index-lifecycle-and-snapshots>>
