2.4. Run Terminal Emulator
Please refer to http://forum.xda-developers.com/showthread.php?t=1015005&highlight=viewpad+7
2.5 Or using Run ADB shell
Here is some of my trials

[or edit in text editor and copy on to Terminal emulator]
That should do the Stock backup of original stock recovery image
[hint: this refer to recovery.img which another post say to change name
of orirecovery.img as not to confuse the files]
2.6 Copy and Change Permission
(I use MyPhoneExplorer to copy file over)
# chmod 755 /system/bin/flash_image
ls -l /system/bin/flash_imagePermission denied
ls -l /system/bin/flash_image
----rwxr-x root root 26172 2011-05-29 17:08 flash_image
2.7 Replace with clockwork stock recovery image
If you have problem with command
flash_image recovery /sdcard/cwrecovery.img
error writing recovery: Permission denied
[hint: do a su command in front before this command]
2.8 Boot to Clockwork stock recovery image
Power off and Power on with both vol key pressed and released
a) You will see 'enter recovery' text
b) Clockwork Menu appear
If only see a) then press reset button and again
flash_image recovery /sdcard/CWrecovery.img
For b) press the vol button to Select 'Backup & Restore'
But the UP/DOWN button always jump 2 steps.
"looks like pressing down moves one and then releasing the button goes another."
My action is to press both volume button but release one to get to
the menu that you want
Then press power button to select
(If press menu button then screen go blank so press reset button)
Once vol and power button to Select 'Backup & Restore' followed by 'Backup'
Press power again to activate backup
you may need at least 300+Mb SD card free
I think may advice to clear cache before backup
The backed up ROM should be located in: /sdcard/clockworkmod/backup/date&time/
Once backup done, use backspace key to go up top menu
Select to "boot"
2.9 Either use "USB storage" or other method
copy those backup into PC as secondary backup
Now I am prepare to go into level 3.
