I recently upgraded to Win 10 on a Dell 660s that is rarely used. After the installation and while learning the new system I realized that "backup and recovery" is nowhere to be found. Doing some research I found that this program was to be updated prior to the installation. (I don't recall getting any nags to do this)
"CAUTION: Before upgrading your system to Windows 10 you must have the latest updates to Dell Backup and Recovery 1.8 installed to ensure that the software will work after the upgrade. For more information please see the following article Dell Backup and Recovery (DBAR) and Windows 10"
Reading the above- it looks like it may to late without reverting back to win 8.1 - any work arounds for this.
Best Regards
