Re: Best backup

Tech-Archive recommends: Fix windows errors by optimizing your registry

Mirroring, in this case RAID 1, is for backup in case of hard drive failure.
This is assuming that all is well with what's written to the first hard
drive originally.

Copying a hard drive is usually a one time affair for replacement of the
original for many reasons not to include hard drive failure. Not suitable
for getting the hardware/software for RAID.
