[Q] Error when trying to nandroid backup with CWM

I made a previous clean backup prior to rooting the phone using the Odin method posted by Copperhed. Still running the stock at&t rom.
All was well. I moved the backup file over to my computer hd to free up space on my external sd card. I was tinkering around with different sd cards last night and accidentally formatted my main sd card that I usually use on my phone. No big deal.
I decided to try out some new roms and kernels so I wanted to make a nandroid backup. Instead of using the odin method to install cwm, I downloaded rom manager and flashed clockworkmod recovery.
I formatted the sd card to make sure space wasnt an issue. I clicked on Backup Current ROM, it was given superuser access and the phone rebooted into CWM. I thought this part was automated but it wasnt. Once the phone booted into CWM, it just sat there at the menu system.
No problems, I navigated down to backup and restore, then hit backup. I did some google searching and people have said this version (5.0.2.7) of CWM does not show a progress bar while backing up.
After clicking backup, I get the usual screen of it mounting the card and displaying how much space is free, then saying it is backing up boot image, recovery image, and system.
Takes a long while then just gives me this:
Error while making a backup image of /system!
Click to expand...
Click to collapse
Any idea of why this would be happening? I searched around but did not find any solutions. The only core things I have installed on my phone currently is Titanium Backup Pro and SetCPU. The rest are just day to day apps, todolists, camera, games.
I've attached what it looked like below. In case the attachment doesnt work (http://i.imgur.com/2ZIPM.jpg)

Forgot to mention, after rebooting the phone when I get that error, I check the external sd card and see a backup folder, but there are only about 3 files in there, so it makes sense because it failed making a full backup.
I just now tried "back up to internal sd card" and it started working right away.. showing files and progress bar moving.
I guess this works too, I can still move the backup file over to my pc.. but this kind of worries me.. is CWM not seeing my sd card correctly?

Another update..
At the end of the backup run (to internal sd card) I get:
No sd-ext found. Skipping backup of sd-ext.
Click to expand...
Click to collapse
When I mentioned formatting the card earlier, I used the phone itself to format it.

I think it has something to do with the variance between the T-Mobile version of CWM we are using on our Skyrockets and what should actually be on the CWM version for the Skyrocket (which still doesn't exist--wtf?! )
Disregard the error message, it's looking for a folder on the T-Mobile version that isn't on the Skyrocket.
If you used the "Backup to Internal SD Card" from CWM you should be fine. I've backed up this way and restored backups without incident.

so if your phone went through a soft brick or something bad happened messing with different roms and such, youre still able to boot into cwm and restore from the backup file that is stored on your internal sd?
i just want to make sure, in the case that we cannot boot from cwm / access internal sd, that we will be able to do so from the external sd.

I don't have a whole lot of faith in our CWM (which was built for a T Mobile variant). I've had a ton of weird messages any time using it and I'm surprised there isn't more talk about it here. I've seen a lot people casually mention the error messages so I know it isn't just me.
I don't know you'd lose the backup if restoring from a soft brick where you'd have to go back to stock first to fix it (never tried it). But I can tell you that if you flash a rom you don't like or doesn't work right you should be able to successfuly restore a backup made in CWM (after wiping data, etc., of course).

All you have to do is install the rom you had when you made the backup for the data going to the advanced options in backup recovery and restore data only and ready

understood. but in the case that the phone does mess up and for some reason it doesnt read the external sd card, would i still be able to access the internal sd card for my backup with cwm?

Just got my G2SR from ATT. Going through the motion of rooting it following instruction here: http://forum.xda-developers.com/showthread.php?t=1340526
I also tried to do a backup to external SD and get the same "Error while making a backup image of /system"
I searched around and I tried the instruction here http://forum.xda-developers.com/showthread.php?t=1472954 by adding clockworkmod/.hidenandroidprogress in both /sdcard and /sdcard/external_sd/
It's still stuck in "backing up system". I have tried reformatting the SD card and perform error checkin on Windows, but that doesn't fix it.
Has anybody back up to the external SD card with CWM successfully?
And how exactly do we back up to the internal "/sdcard". When I go backup, it would complain I don't have an sdcard if I don't have the external SD card.
[update] I am on ClockworkMod Recovery v5.0.2.6 and I don't see any "backup to internal SD' option. Do I need to update my CWM and how do we do that?
Thanks in advance.

[Q] Restoring backup

Hi,
I've been trying to return to a backup i made before flashing the latest build and cwm recovery keeps spitting out errors. My backup copy is under /emmc/clockwork/backup. It shows up under cwm recovery when i go to 'backup and restore' but it won't flash. i thought maybe because its on the internal drive its not flashing and tried to move it to the /mnt/sdcard. It won't move! Its my first flash so i need some help. it seems after flashing cm7, my old data is under /emmc and my current stuff is going to /mnt/sdcard. my understanding is that restoring the backup would overwrite everything and restore the phone to stock state (partitions, data everything)...is that right???? currently i have a 14gb internal and 2gb external partititions.

There is a fix somewhere to reroute the file path back from emmc back to internal SD . You ll need Script Manager from the market and a script called ''mountshd" . Someone posted a download with some good instructions a while back I would search the forum

How Nandroid Internel SD?

I am useing CWM 6.0.1 Recovery because it is kexec enabled . I am trying to do a full nandroid backup including the sd card (internal). I have tried the mount /sdcard option and i click backup and i always get. no /sdcard/.android_secure found skipping backup
My apps go on the internal sd card right?
I just restored a nandroid backup from beans rom to Stock and everything seemed right execept the boot logo still has the unlocked logo on it! Factory reset and its still there as well?
Is there anyway to back up internal SD with any recovery?
Why does it feel like nandroid isnt backing it all up and everything isnt the same on restores?
where are the programs installed to if the nandroid backup doesnt include the internal SD? the system
partiton? If so do we have 32gb for apps or just the stem partition?
THANKS
VERY NEW

[Q] Nandroid Back-Up Issues

Hello,
While attempting to flash my very first ROM, I got the following message at the completion off doing a Nandroid backup:
No /sdcard/.android_secure found. Skipping backup of applications on external storage.
Backing up cache…
No sd-ext found. Skipping backup of sd-ext.
Backup complete!
I do have an external SD card. The ROM I was attempting to flash is on my eternal memory card.
I used ROM Manager to do this. Any thoughts will be greatly appreciated!!

That's normal, it's looking for a separate partition called sd-ext which would be on the internal phone storage. You haven't created partitions within your internal sd card so it will say that every time. Mine states the same thing right before it completes Nandroid backups. The entire line that you quoted, ignore it and flash a rom. Your backup completed successfully correct?
"Sd-ext" does not mean external sd card.

Twrp (restore

Hello,
I made a backup of my phone using TWRP. When I try to restore from the backup I created, I get a "E:extractTarFork() process ended with ERROR=255" error message when it tries to restore the data.
Anyone know the fix for this?

Not much information there to even begin.
Did you back up to SD or internal storage? Did you back up everything except SD card? Is the phone set to use system storage as default install and storage space?
IMO, it works best when you don't allow the phone to use the SD card as install/storage, then a backup to SD, including all partitions is easy to restore. Also allow it to write an md5 checksum.
Most likely, you can't fix it now and will have to start again.
