Also, I was running Disk Utility at the time of first backup attempt to create a second disk image in parallel on the external storage (where I had already created a 150GB disk image for backup, and was backing up using SuperDuper). The disk utility aborted creating that disk image - didn't tell me why. I wonder if it affected the backup operation in anyway.

Which files are being excluded by SuperDuper? If I find it out the list of those files, I can find out which files are contributing to doubling of the space...SuperDuper is correctly copying original 47GB instead of doubled 97Gb...So, the excluded set is mostly made up of the files that doubled the disk space...
