Don't be hehe.
Download and install Rom Manager from the market.
Don't worry about all the options it offers. All you need to do is tap on "Backup Current Rom".
Give it a name you will remember " MyMainBackUp" or something.
Once you enter name it will boot into recovery by itself and start backing up.
Once it is done it will ask you to fix boot, just select no.
It will boot into system.
You are now backed up - It will backup to your gpd memory by default.
To see your backup and put it on your pc, Rom Manager has a cool feature.
Tap on "Manage and Restore Backups".
Tap on "Download Backups".
Now on your pc (must be on same network - if you connect to the internet the same way with pc and gpd you are good) open a browser ( Internet explorer, chrome, firefox .... ) and in the address bar put the address it shows on gpd.
And easy peasy booyah. =) , download the backup to pc.
Once you are done you can go back to the backup list on your gpd and delete it if you like.
If you want to use your card instead of using internal memory to save your backup, go into settings ( upper right side - 3 vertical dots ) and tap on "settings". Then turn on " Use External Storage" - make sure its on. Make sure your card is formatted in FAT32 if you do.
Play with it if you like you wont break anything. If you want to restore a backup just go to "Manage and Restore Backups" and tap on the backup you want to restore. Then tap "Restore".
If you have the backup on your pc, first put it into your card in one of the 2 directories:
The main reason for using this recovery is it's ability to restore EVERYTHING. You will restore your backup and it will be in the exact state as you left it in.
It is pretty easy. Let me know how it works for you.
