I’ve been attempting to backup my notebook by creating a disk image using Disks. It couldn’t look more straightforward, yet I keep running into the following error. The confusing part to me is that /dev/sda3 shouldn’t have anything to do with the drive I’m looking to create an image from (/dev/sda1). Does anyone have suggestions on how to create a disk image in an alternative fashion?
Error unmounting /dev/sda3: Command-line `umount "/dev/sda3" exited with non-zero exit status 32: umount: /tmp: target is busy
(In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).)

Yes, I’d like to backup the entire disk. Although, I could simply create individual .img files for each partition… perhaps that’s my problem? My root partition uses the Btrfs filesystem, whereas my home partition uses XFS.
I use luckybackup which is a GUI front to rsync. Rsync does a sync so is much faster then copying all the files every time only changed files get updated. Note the backup drive should be formatted with a Linux file system. Windows FS do not preserver permissions and ownership
