If you have selected to back up to iCloud in settings your phone won't automatically back up to your computer. However, you can still manually back it up using iTunes whenever you want by connecting it to your computer, opening iTunes, clicking on the name of your phone in iTunes, going to the Summary tab of your iTunes sync settings, then clicking on Back Up Now under Manually Back Up and Restore.
If you can't back up to iCloud, this may be caused by a corrupt existing backup that needs to be deleted, or by data on your phone that is preventing the backup. To troubleshoot these, try deleting your last backup (if you have one) by turning off iCloud Backup in Settings>iCloud>Storage & Backup, then tap Manage Storage, swipe across your backup and tap Delete, then go back and turn iCloud Backup back on again. If it still won't back up, you may have an app that is preventing the backup from succeeding. To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again. If it succeeds, then the camera roll and/or one of your apps is preventing the backup and you'll have to located by process of elimination. Turn the camera roll On and try backing up again. If it succeeds, turn some of your apps to On and try backing up again. If it succeeds again, turn some more apps to On then try again; repeat this process until it fails. Eventually you'll be able to locate the problem app and exclude it from your backup.
