By default, CCC uses the name and Universally Unique Identifier (UUID) of your source and target to identify those volumes. By verifying both of these identifiers, there is less risk in, for example, backing up to a volume that has the same name as your usual target but is not actually the target. While beneficial, this behavior can sometimes have the wrong result. For example, if you rotate between a pair of external hard drives, even though they have the same name (e.g. "Offsite Backup"), CCC will not, by default, backup to both of them, it will claim that the UUID of one of the drives does not match that of the originally chosen target.
The deal with this scenario, CCC allows you to disable verification of the target drive's UUID. When deselecting this option, be vigilant that you do not rename your target hard drive and that you never attach a hard drive to your machine that is named the same as your target hard drive.

In addition to disabling the UUID verification, CCC will also allow you to disable verification of the target volume's name. Obviously, both of these options may not be disabled at the same time (CCC won't let you do that), but in cases where you may want to rename your target hard drive, this option will allow you to do so without breaking your scheduled backup task.
If your target hard drive is an iPod, CCC will provide an additional option in the Settings tab: "Wait for iPod:iTunes sync to complete before copying data". When you bought your iPod, you probably did so with the intention of using it to enjoy your music collection. To this end, Carbon Copy Cloner recognizes that the primary purpose of an iPod is for music, and respects the synchronization period that occurs when you connect your iPod to your Mac. This option is enabled by default.
Waiting for iPod:iTunes synchronization
In some instances, it may appear that iPod:iTunes synchronization has started, yet CCC begins the backup task anyway. CCC determines whether the synchronization is occurring based on whether the synchronization background tool is running, not what is described in the iTunes interface. Before iTunes actually starts the synchronization, it determines when it last synced your iPod and then prepares data to be copied to your iPod (calendars, music, contacts, etc.). Depending on how much data it has to prepare to send to your iPod and how fast your computer is, iTunes may take more than a minute preparing to copy data to your iPod. If iPod:iTunes synchronization hasn't started in one minute, CCC proceeds with the backup task anyway. This time interval is not configurable, but seemed like an adequate middle ground between waiting too long for a sync task that may have been cancelled anyway and not waiting long enough for an iPod long overdue for a sync. If CCC starts a backup task before iPod:iTunes synchronization has completed, you may, if desired, click CCC's Stop button and defer the task to a later time.
The Description tab indicates the name that you have provided for your backup task as well as a description of the task. CCC populates this description with the one provided in the main interface, but you may modify this description to suit your needs.
