# Updating archives on Amazon EventBridge event buses
<a name="event-bus-update-archive"></a>

You can update the following: 
+ Archive description
+ The event pattern used to filter which events are sent to the archive.
+ The retention period for events.
+ The Amazon KMS key used for event encryption.

  For more information, see [Encrypting archives](encryption-archives.md).

You cannot change the name or source event bus for an archive once it has been created.

**Note**  
Schema discovery is not supported for event buses encrypted using a customer managed key. To enable schema discovery on an event bus, choose to use an Amazon owned key. For more information, see [KMS key options](eb-encryption-at-rest-key-options.md).
