If using a dual boot system, linux and windows, is there any way linux can make a backup of the whole system ? ie linux and windows.
Having been caught out by making a back up of the windows partition only to discover a failing hard drive could only be read by linux . I do not want to be caught out again.
I periodically boot from a Linux USB and copy all files Partion-1 -> Partition-1 on backup device, Partion-2 -> Partition-2 on backup device etc. This way, I get a file level backup.
It is essential that you run your backup from a separate OS.
The massive initial copy will take ages, so you need to use rsync for future backups to get some speed!
Personally, I format the external disk with LVM, for flexibility.

I use Acronis True image for backups. That should allow you to back-up the entire hard drive. You can do this from a boot disk but that's not necessary if you are running it under Windows.
