Do you have a computer with iTunes? Or an iCloud account? And what exactly do you want to backup? Is it that you want to backup for safekeeping, or you want to create a backup then restore that to a new device? Oh, and what iOS version is on the iPad?
I have a Mac with iTunes. I probably can install iTunes on the PC. Does it matter Windows of Mac OS?
I don't have an iCloud account but it seems that I can get 5GB for free.
I want to take my iPad 2 to Apple for testing. The staff asked me to backup first as the data might be lost during the test.

There are some problems with the iPad 2. Cannot connect to iTunes Store nor FaceTime.
