I have a La Cie 4TB external hard drive to back-up my MacBook Pro. How do I back-up my external hard-drive ( just in case it ceases to function properly or at all )?
MacBook Pro with Retina display, OS X Mavericks (10.9.1)
Are you using this drive as a Time Machine backup?
You can connect as second external hard drive and configure Time Machine to use that drive as well. Then Time Machine will alternate every hour between the drives. Then when one of those fails, you will have a backup which is no more than an hour old.

Get another drive large enough for the backup, then use Disk Utility's Restore option to clone the backup drive to the new drive. Be sure you partition and format the new drive for use with OS X beforehand.
You can do it with the built in time machine https://support.apple.com/en-us/HT201250 This, when run will keep a current backup of you system and personal files. Or here are some other options for doing this. https://discussions.apple.com/docs/DOC-3045
