The ancestor calculation was wrong for incremental backups: when requesting the ancestors for an incremental backup X, the ancestors could include both full and incremental backups that predate the full backup on which X is built. This caused a crash in incremental backup creation when data of old incremental backups was deleted through other means than the HBase API (i.e. without the HBase backup system table being updated).
