Q: Time Machine failed to do backup. What are the alternative backup software?

A MBP with 1TB HD failed to continue Time Machine backup, after OS X upgrade to El Capitan 10.11.6. Old TM backups were automatically deleted due to verification error. The MBP also failed to do any new TM backup.

I guess I may need an OS X reinstallation. How safe is it to reinstall OS X 10.11.6 without a backup? Any suggestion of a disk cloning software? (e.g. Can Carbon Copy do a disk clone? How?)

MacBook Pro, OS X El Capitan (10.11.4), 16GB 1600 MHz DDR3

You should check the drive you were using for Time Machine backups with Disk Utility > First Aid to make sure the drive is okay. If you mean Carbon Copy Cloner, yes it can create clones. The instructions to create a clone are included with the program.

Startup disk and TM backup drives are checked with Disk Utility. Other Macs are doing TM backups on those TM backup drives smoothly via Wi-Fi or GbE. So I think it's the OS X of the MBP making the trouble.
