We ran into a lot of problems using a finalizer on the backup to allow the Ark server to clean up all associated backup data when deleting a backup. Users also found it less than desirable that deleting the heptio-ark namespace resulted in all the backup data being deleted. This removes the finalizer and replaces it with an explicit DeleteBackupRequest that is created as a means of requesting the deletion of a backup and all its associated data. This is what `ark backup delete` does. If you use kubectl to delete a backup or to delete the heptio-ark namespace, this no longer deletes associated backups. Additionally, as long as the heptio-ark namespace still exists, the Ark server's BackupSyncController will continually sync backups into the heptio-ark namespace from object storage.
