I need help with firevault and a external hard drive

I Just purchased a LaCie Porsche Design 2 TB external hard drive, I installed it successfully but my computer says the fire vault needs to encrypt the "Machintosh HD" disk before I can use Time Machine to back up my computer. It says it has more then one day remaining before the firevault finishes. Should I wait for the fire vault to finish and then use time machine or turn the fire vault completely off then back it up?

iPhone 6s, iOS 9.3

Do you require your backup be encrypted? Is your main drive encrypted? And, it's called FileVault. Unless you work for the NSA or CIA or have extremely sensitive information you wish to keep from prying eyes, there isn't much need for disk encryption.


Disk encryption can take a very long time depending on the disk size. Decrypting the entire disk takes just as long.
