+### Yaffs2 override:
+* CWM has an old method of backing-up yaffs2 partitions as yaffs2 images, instead of tar balls. Since Online Nandroid follows the same formats used by CWM, it follows the same method as well. This has a side affect in some cases (specially if internal sdcard lives in /data/media or if an sd-ext setup is used). To overcome this, Online Nandroid can do tar backups for yaffs2 partitions as well. The override flag is:
+```shell
+onandroid -y
+OR
+onandroid --yaffs-override
+```
