Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

Samsung users can also back up data using Samsung KIES. If you backup data manually, you get more options what to choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your tablet, we strongly recommend you to also backup using that as it creates a complete image of your existing tablet set up.
A few more optional tips that you should remember:
1. Having problems connecting your Android tablet to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and Developer Preview 3.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your tablet goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your tablet might get bricked or go dead permanently. No one wants that, right?
4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your tablet is locked to a carrier, unless we have specified the carrier name or device model.
