Hello A75 users, I have a good news for you.
Using varun's recovery as base I successfully ported sd-ext support to CWM Recovery v5.0.2.8 for A75.
Now recovery is able to mount, backup and restore sd-ext.
Recovery is tested by me as of now, I don't know if any other users tested it or not.

ADVANTAGE OVER PREVIOUS VERSION:
Till now the recovery was not able to backup sdext partition means 2nd partition of sdcard which we use to move apps using Link2sd app.Without its backup u can't completely restore the phone to previous state,u can restore system only.if u also restore data then without sdext backup it won't give ur apps installed on 2nd partition, u will hv to install them again.
So now the recovery is complete, it does what it should.nandroid backup is now complete n u can backup and restore the whole rom without any problem.

I will provide two methods to flash this recovery.
1) For the users who are still on stock recovery(this also work for cwm users)
2) For the users who already have CWM by varun

Ok,enough chitchat,coming to the steps & links.

1) FOR USERS ON STOCK RECOVERY OR CWM

1st install Terminal Emulator(adb can also be used), put recovery.img and flash_image binary in root of sdcard.
Open terminal Emulator n apply following commands one by one.('Enter' after each command )

Code: 
su

mount -o remount,exec /dev/block//vold/179:1 /sdcard

cd /sdcard

./flash_image recovery /sdcard/recovery.img

2) FOR USERS ON CWM RECOVERY

Here I give u a flashable zip which u can use via recovery just like u flash a rom.

Code: 
Put the zip to root of sdcard, rename it to CWM.zip(not necessary though)

Power off the phone, boot into recovery by holding volume up + power on.

Now select, Install zip from sdcard

Choose zip from sdcard

Select your CWM.zip file

Confirm and U r done.
DOWNLOADS:

1) Recovery image only: recovery.img
2) Flashable zip: CWM5-A75-sdext-mastermind.zip
3) flash_image binary for Terminal Emulator method: flash_image

This method was not working for me so i did the same thing what i did with the Varuns recovery and had changed the flash_image also as it dint work for me the first time also so have downloaded the smaller sized flash_image and followed these steps

1. Extract the flash_image binary to your sd card( Don't extract it in any folder, extract it in open that is root of sd card
2. Copy that extracted flash_image binary file to system/bin using root explorer and after that long press on the same file and select permissions and a dialog box will appear with few empty check boxes, tick all the check boxes and tap OK
3. Now place the recovery image in sd card( keep it open and not inside any folder)
4. Fire up terminal emulator and type
Code:
su
and press enter and grant the root access
5. Then type
Code:
flash_image.bin recovery /sdcard/recovery.img
and press enter
6. Then type
Code:
reboot recovery
and press enter and this will take you to new recovery!!

Below is the link for the smaller size flash_image.bin file

flash_image download - 2shared

so if anyone find any difficulty in following the steps provided above then can follow what i have provided and you will be in new recovery.
 
Recovery has nothing to do with ROMs.its not a rom specific thing.
Your JetMOD.zip must be corrupt,fresh copy to the sdcard JetMOD.zip n try again or download fresh copy of it.
N about flashing recovery image, I don't know why it didn't work for u, I tested all methods I described. All works fine.n I have attached flash_image binary file too which works fine,I personally tested it n the method several times.
I never post anything without testing.

Hey i understand that the method what u have provided is tested but may be it doesn't work for some phones like mine as there were few others also who faced the problem with varun's recovery and at that time only i came to know that there is some problem between our phone and flash image so i searched the net and found new recovery and flash it. As i was getting the same problem with ur method so i tried the same method what i did previously and got it done. i have just provided the method so that if some one is getting the problem what i was facing then they can just use the method what i provided. I m sorry if i m wrong but my intention was just to let others know that they have an other option to use the recovery moded by u.

And haan there was a problem with JET MOD.zip what i was having so i downloaded new one and flashed it and now i m using the same with the updates till JET MOD 3.03 BUT STILL DINT GOT THAT FREE SPARED SPACE WHAT U HAVE MENTIONED I first tried it with the stock ROM after ROOTING but nothing was happening so have switched to JET MOD as its fast n speed. If u can provide me the steps to free that spared space i will be greatful to u.

Any ways thanks for providing us this recovery now we can atleast have the full backup.
 
thanks mastermind,it work . when flash recovery with flashtool it's not work( but my friend it's work) keep moving with another projeck,may be new room(gb 2.3.6/2.3.7 or maybe ics)

I think u used flashabe zip, if u already have CWM recovery from varun then u can update using this flashable zip n there is also an option to disable signature verification in Advanced menu of recovery...
But if u r on stock recovery (having yellow fonts) then may be flashable zip will not work..in this case, if u r rooted then use Terminal Emulator method...
 
yours recovery is not working after installing ics3.0, backup was created but in recovery it is saying md5checksum failed

That error is not due to recovery, don't conclude any problem directly to recovery.
Error is because may be any of ur image file has got corrupted, thats can be the only reason.
Sometimes if u rename backup folder then also recovery shows such error n thats for all recovery including other devices..its a bug.
If u feel ur images are fine n not corrupted then do this, ur backup will be restored fine.
Open nandroid.md5 file with text editor, delete all contents,save n close n it will do.
