Hi,
Having CWM installed on the recovery partition, I tried to perform a Nandroid backup to the microSD card.
As I cannot find any valid partition system on the SDCard after the backup, I have the following questions :
1) Should the microSD card be formatted before making the Nandroid backup, and should it be in FAT16 or FAT32 ?
2) Which is the nature of a Nandroid backup : an ".img" file containing all partitions as well as the folders and files in them ?
The backup does not seem cloning the partitions but copying files from a mounted filesystem.
Is the backup some kind of archive of the copied files ?
3) At the beginning of the backup process, CWM tells "SD Card space free 6301 MB", whilst the microSD card is only 1 GB.
Does this mean that I need a 8 GB sd card to perform the full backup ?
4) To extract files from the backup using Windows or Linux, should I then use the "unyaffs" utitity ?
Thanks.

Could someone please confirm the process to me for changing an SD card when you current one already has an ext app2sd partition?
This is my guess but would like confirmation before I go at it.
Go to recovery console
Nandroid + ext backup
Copy nandroid backup to PC
Partition new SD
Copy nandroid to new SD
Nandroid restore from console
Thanks
Never mind, found the answer in the CDMA forums

if i back up my rom and format my sd card partitions will it destroy my back up
Yes, backups are stored on the sdcard. Copy your backup to your computer first
I am using openOptimus build 2.202.1 with 2 GB sdcard, which is partitioned as
MBR 1 block
FAT32 1.36GB
disk1s2 Linux Ext2FS 487.57 MB
and now i wish to upgrade to 4GB sdcard. How can i do it unambiguously?
From things i know, in Windows Mobile and Symbian systems, changing memory card does not make trouble. Also i think you should copy all your data to some folder on desktop, make Partition Copy of sdcard then start changing process (copying data).
I've changed 2GB card to 8GB card (soon to 16GB) and my android does not seem to notice that change. (just more free placoe)
You can also copy data from previous, insert new into android, let it meet your new sdcard, then put it out and copy rest of data..
This is what i did :
1. first partitioned the new sdcard from recovery
2. copied the contents by mounting usb storage.
up and going. thanks .
If you have a2sd ext partition you should make a nand backup on your 2gb card to backup ext partition, then you copy all contents to your 4gb card and restore nand.
Hello All,
Just got a white one without any external SD-Card (the micro SD) installed. I was able to root it using the CF-ROOT V5.0 guide which is an excellent resource for noobs like me.
Using the CWM (which shows in the applications menu after the root) I was able to take phone complete backup.
Now the confusion begins that even though there was no external SD card installed the backup took place and then it was saved in
Code:
/sdcard/Clockworkmod/backup/folder_name_date_time
Infact /sdcard is the home directory to start with, which is shown when I browse files using the built-in file manager called "My Files".
So when is there is no SD-Card installed, why is the internal home directory called SD-Card , where the nandroid backups are saved automatically ? (i guess the internal storage is also called SD-Card, is it so ? bad naming idea then)
Now I did install a 2GB external SD-card and formatted it using the storage options within the settings menu.
So apparently this (actual) SD-card is mounted in the directory called
Code:
/sdcard/external_sd
Then again I tried taking a nandriod backup hoping that it would automatically detect this available external sd card and would save the backups, which did not happen and the nandroid again took backup to the internal SD storage.
So how to direct nandroid to take and place backups on the external SD card.?
Secondly I have also read about the Sd-Ext partition, can someone please explain what is this partition , how is it made, and what is the benefit of using this partition. Can i make it a default location for installing application and what other uses can I have of an SD-Ext partition.?
Do i need App2SD and Link2SD in order to use SD-ext partition for any purposes.?
If I take a backup again using nadriod would it place it on the SD-Ext partition or the left over space in the regular SD card partition. ?
Thanks a lot for reading and clearing up my confusion mentioned above.
Internal card is named SD card in CWM .
Me i just copy the clockwork backup folder to PC and External SD card .

Well,
Thanks however I am hoping some more details to satisfy the specific queries I had, waiting for the gurus to shed some light.
Thanks again.
Hi guys!
I have really particular question, which I have not found any answer to. I have my microSD card partitioned and I did backup of the system with CWM, but I have marked sd-ext option too. Now I have few questions:
1) So when I will format my microSD card and don't create new partition, then recover my earlier done backup of my system and sd-ext through CWM , will second partition (ext4) will also be recreated? or I should re-partition my microSD and then recover my sd-ext files through CMW?
2) When re-partition is needed, can I choose create ext2 and recover my sd-ext data which was on ext4? is it possible?
3) When I know that my backed up files on second partition was for example 4GB, and I still had 6GB free space (both give 10GB in total), can I shrink my newly created second partition to 8GB in total, and leaving 4 GB free space instead of 6GB before. Will it affect recovered through CWM files?
4) And lastly I would like to know when I copy microSD files to computer, files are only those from first FAT32 partition? When I wipe my microSD and copy these files back to microSD, I assume all my ext4 (second partition) files are lost? and then, all linked apps through link2sd will be broken (deleted?)? There is only one option to backup them and is it through CWM recovery with "sd-ext" option? or is there anything else?
