Two types of users will appreciate AOMEI Backupper Pro:
1 - Those with PCIe drives (and haven't found cloning software that works on them).
2 - Those who want a fast clone of their boot drive (no re-boots needed) and it can clone your drive while other apps are running.
If interested, be warned: AOMEI is $50 (USD) for 2 PCs and is paid to a 3rd party. AOMEI will email the key and a download link. If you lose the key or the link, then it's $50 for nada as there is no way to get the link without another purchase and if you lose the key, AOMEI doesn't file it.
It works with all versions of Windows XP, Vista, 7, 8, 8.1 and 10.
