Optional. Example:
//memorystore.googleapis.com/projects/{project}/locations/{location}/backupCollections/{collection}/backups/{backup}
A shorter version (without the prefix) of the backup name is also
supported, like
projects/{project}/locations/{location}/backupCollections/{collection}/backups/{backup_id}
In this case, it assumes the backup is under memorystore.googleapis.com.

<code>string backup = 1 [(.google.api.field_behavior) = OPTIONAL];</code>

@return The bytes for backup.
