Event code: 0x000101F6+0x00070002 for failed backup Acronic True Image 2014

I'm trying to backup my new ssd with the OS (Just upgraded to Windows 10 Pro) on it.  I've tried several times (using different settings) without success.  Under event details it says:

Operation with partition '3-0' was terminated.

Details:

Not enough memory (0x70002)

Tag = 0x82DB9339B70C3B24

Under error code it says:

More information about this error and solutions may be available online in the Acronis Knowledge Base.
To access the online resource manually, enter the event code at: http://kb.acronis.com/errorcode/
Event code: 0x000101F6+0x00070002

Sadly, the online resource only lists Acronis True Image 2016 as an option, nothing earlier so I can't check it manually.  Don't know what the "Not enough memory" is about.  Destination hard drive has almost 500GB free.  If anyone here has any idea what this is about and/or how to go about correcting this I would appreciate it.  Otherwise, I guess I'll have to upgrade to 2016 and see how that works out...
