I only have a couple of VST's that use iLok, but haven't had any problems even when I moved to a new PC. I did have an iLok go bad and fortunately I bought it from Sweetwater and it was still under the Sweetwater 2nd year warranty and they replaced it. I did have to "jump through hoops" to get iLok to transfer my licenses to the new iLok. I agree with don't buy anything that requires iLok, what I have with iLok I'll keep but any future purchases will not include anything that uses iLok.
I use Macrium Reflect (paid version) for my full hard drive backups (the free version will work for most). I used to use Acronis but it failed me twice trying to restore and it didn't get a third chance, I dumped it. The Macrium backups take less time than the Acronis backups did. In addition Macrium automates the WinPE Rescue Disk creation operation, with Acronis it requires having the Plus version and it is a manual process. Another issue, I had problems with the standard Acronis bootable rescue disk which uses Linux as it wouldn't work correctly on either my Gigabyte motherboard system or my ASUS motherboard system (wouldn't recognize all the hard drives connected). The WinPE bootable rescue disk does recognize all the drives attached.
