If there wasn't errors, then you backed up such partitions:
```
[root@WCV3:~]# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00008000 "boot"
mtd1: 001f0000 00008000 "kernel"
mtd2: 003d0000 00008000 "rootfs"
mtd3: 003d0000 00008000 "app"
mtd4: 001f0000 00008000 "kback"
mtd5: 003d0000 00008000 "aback"
mtd6: 00060000 00008000 "cfg"
mtd7: 00010000 00008000 "para"
```
Save and keep this files in safe place.
In case of any errors you should perform this operation once again, probably with microSD card replacement.
