[Q] Wiping ext2 partition, then restoring it.

---

I want to clean up my ext 2 prtition because my phone has been running funny lately. If I perform a backup using Backup for Root users (which I think backs it up on the fat32 partition), then wipe my ext2 partition using

adb remount
adb shell
rm -r /system/sd/*

Then I use Backup for Root Users to restore everything, That should work fine right?

(I also have My Backup Pro, but I think it is terrible)

Any information or opinions would be appreciated.

Um no all wrong. No app in my knowledge backups your ext2 partition. Why should you want to back it up anyways? If you restore your apps then they'll automatically go back to your sdcard and so will dalvik cache (depending on what ROMS). You can always "adb pull /system/sd/* C:\Users\xxx\Desktop" that will backup your ext2 partition and you can push it back after. Sorry for the long answer and having the answer at the end
