By default, they're written to <datadir>/BACKUP/BACKUP-<backupid> on every data node. You'll need to collect all the pieces from every data node to have a complete backup.

You'll ideally want to set BackupDataDir to different storage than your datadir for production use. If the backup fills up the disk, it will kill the node. This is especially bad since the backup writes to all data nodes and could potentially fill/crash them at once ;).
