Not an ideal idea at all, if you want a clone, use SuperDuper and clone the TM backup.
SuperDuper is free, it clones one drive to another
Cloning the 1st HD (your original) is best option if you want a redundant copy of a TM backup.
Ideally TM is a system backup, and NOT a data archive. This is why time machine is a "bad" premise for data archives, its buried inside time machine, and quick data extraction is "less than fast".
No, dont worry about moving files from TM to computer or otherwise. You just want a redundant copy.
In the future consider making DATA only (things you made, / saved / created/ etc.) in files on an autonomous HD and leave Time machining for backing up the computer and its resident files.
While time machine is a backup, people make a hyperbolic 'error' out of this thinking that "time machine is therefore a backup/archive of my valuable data etc." its "not", and "not safe" on time machine.
see here for idealized use of time machine:
Methodology to protect your data. Backups vs. Archives. Long-term data protection
Time machine is also a "revolving door" and when out of space erases older files.
Worst still you have no genuine verification that your vital data is ON time machine UNTIL you need it in an emergency, and thats a BAD working premise.
Its like throwing emergency supplies in a dark basement and never knowing if its all still "down there" until you need it.
It could be corrupted, and in the case of "when full old files are erased" time machine is like having a window open on "the basement" and important stuff is spilling out the window into oblivion.
