How do I manually backup my iMac to my cloud

I am trying to backup my imac HD(The complete works) to my WDMycloud 2TB harddrive. I have backed up iPhotos but wish to backup the complete harddrive in one go,can anyone advise me please.

Have you looked at the  User Manual and read about setting up Apple Time Machine, (Page 27, Using Apple Time Machine)?

cat0w,Hi,

Thanks for the response.

I am not able to use Timemachine for some obscure reason. I have had several sessions with both Apple and WD support and have been advised that a manual (without timemachine) download is advised.

I have manually downloaded iPhoto and iTunes successfully,both operations were complex and time consuming.

I just wanted to do a full HD backup before downloading Yosemite.

Regards
