how to backup iPad

[rockydoc]

I have an iPad 2, an iPad 3. I have an iMac 21.5" and a time Capsule on local wifi personal network. Time Machine backs up my iMac to Time Capsule. How can I back up my iPads?

You can backup your iPads using iTunes on your iMac, or iCloud: http://support.apple.com/kb/HT5262
