ClockworkMod Recovery failing to restore backups

S

Hi all... Any insight on this would be greatly appreciated.

I've got to be doing something wrong (but c'mon, really how can you screw it up?) because this is the second time ClockworkMod (v.3.0.2.4 on my Nexus S) has let me down. First time on my Desire Z, this time on brand new hardware my Nexus S.

When creating the backup, ClockworkMod tells me that the backup was created successfully, but halfway through the restore of said backup (after full data wipe, cache wipe, dalvik wipe) the restore process stops and I'm back at the bootloader with no confirmation of success or failure. Then, when I reboot the system, I'm greeted with the Android setup wizard and a half-restored system.

Two of my last backups that were 'successfully created' fail to restore in the exact same manner. It's frustrating because the MD5's check out OK using AFV.

When I do an advanced restore, the Boot restores OK, the system restores OK, but it's during the data restore it stops. Why is this happening?

I've got 6+GB space free on my storage, space isn't an issue when creating the backup.

If it matters, I'm trying to restore CM 7 backups after fidling around with another ROM this morning.

This is really disheartening... Any suggestions?
 
What a time vampire this has been... I have no idea what's up. Could it possibly be an app that's in the backup that's causing the restore to fail? How on earth could I narrow it down? I've even tried making backups of a different ROM with the same apps and still no dice. Still fails restoring the data.

*le-sigh.*
 
How did you install CWM Recovery? Via ROM Manager?
If yes, this can be the problem.

You could also try an older version of CWM Recovery.

I did flash CWM Recovery through ROM manager. Should I flash it through fastboot instead? When I tried flashing an older version 3.0.0.5 (again, through ROM manager) I get a mount error on the /cache directory (failed to find "cache" parition to mount at "/cache") which is an issue apparently with my specific i9020a (Koodo) Nexus S.
 
Update...

After customizing a fresh CM 7.0.3 install, restoring my data from Titanium I decided to give CWM another shot, but before I created the backup I cleared all the cache from my apps. I noticed that Tweetdeck had over 65MB of cache on the internal memory and wondered if it was somehow a culprit in the backup problem. I used CacheCleaner NG to wipe the data, created a backup, wiped the data, and restored the backup and it worked.

At least I know I now have a backup. Could an app really cause problems?
 
Could be.
The thing is if you use an application (like ROM Manager) that tries to simulate a backup/restore environment, then the chance of mistakes is higher.
I prefer backup/restore from CWM recovery (btw I'm using v2.5.0.7). There you can also do wipe/factory reset and cache wipe.
 
I may have your problem.

Last night, I installed TW 4.5/TW Manager. I did a ClockworkMod backup first. I decided to restore it.

However, after restoration, the phone is in a factory state. Save for my lock pattern, which it remembered, the phone is in first-run setup mode, all my home screen layouts are gone, all my apps are not in the aop drawer except those the G2 ships with. Contents of the virtual SD card like photos are still there.

I tried restoring my only other CWM backup (a November backup that previously *restored ok* to undo a MIUI test, for example), but this, too, now boots in to the same state.

What has gone wrong here?

And is there any way of getting back the system that I assume/d is/was in the CWM backup files?

If I can't guarantee I can restore a CWM backup, it makes the world a very scary place to be.

I did not receive any errors on restoration. It goes right in to the recovery menu, from where I reboot.

Don't know what the answer is :-(
