Try CarbonCopyCloner or SuperDuper instead.
Either will create a bootable clone of your internal hard drive.
No "over and over" copies of the same files.
CCC can also "archive" older versions of files, IF you tell it to.
CCC can also create a clone of your recovery partition on your backup drive.
TM doesn't make ""over and over" copies of the same files", it only copies changed files since the last TM backup.
Finding archived older versions of files would generally be much more difficult with CCC than with TM.
CCC is better in terms of creating a cloned drive you can boot from.
I use both. I am using CCC for the catastrophic disk fail type error, and TM for the user error, finger fumble problem. And it's always better to have different types of backup.
