I was just wondering if cloning or imaging is able to clear the nasties you work with that do survive a format? Would the image restore go deeper on the HDD to overwrite the surviving malware?
That's a good question.
My understanding of this is that, the main difference between cloning & imaging is:
- Cloning copies the HDD bit-by-bit for an exact photo of the Source HDD.
- Imaging effectively does the same thing (if selecting a full-disc image) but it compresses the copy via a proprietary method.
Acronis uses a *,TIB extension method. From what I've been reading about Imaging in general, is that an advantage of that approach is that you can have multiple copies on a backup HDD, ie, an external drive.
However, since I've been digging into this lately, the compression ratio isn't what I had thought, at least with one recommended Imaging tool ("Macrium"). That tool apparently compresses by approx. 50% ratio.
When I began reading up on Imaging, I had a vision that I could store 5-10 full-disc images on say, a 2 Tb external HDD. When reading further about this, that's not typically going to work since video and photo files don't compress as well or as small as OS and other typical files on a typical HDD.
These are reasons that, so far, I've stayed with cloning until I can research the Imaging idea further and select a utility that may be more efficient than Acronis's Imaging method.
I'm happy with Acronis cloning. It takes about 40 minutes to clone my 1 Tb HDD. I've also used the freeware tool "Clonezilla". That one, for me, took about 1 hr or a little longer.
I prefer Acronis since it's more user-friendly, with the gui screens, etc. Clonezilla requires more caution, even with the "beginner" mode. I didn't have any problems with it but it's mainly recommended for the more experienced user.
One advantage to me, with cloning, is the faster recovery time vs Imaging, Recovering with a cloned HDD doesn't require booting up with the Imaging utility, then performing the "recover" action.
When I recently imaged my Source HDD using Acronis, the "backup" step took about 5 hours. This is with Sata transfer speeds, using my Tower Sata hot-swap trays.
