I have PC with 1 disk with 2 partitions (system and data). The data partition is mirrorred to a NAS, so I do not need a backup of that one. I frequently create a differential backup of the system disk to a USB drive, using Acronis TIH2009. Suppose my disk crashes and is not readable at all, so I need to replace it with a new disk (probably not the same size, but still in the same PC). What is the procedure to restore the system partition to this disk, making it work as before? Do I need to be aware of special settings during backups? So, I am not talking about cloning of an existing system, but creating an (unexpected) clone while the original disk is not available anymore. My biggest fear is creating frequent images and not being able to restore when I need it, because I made a mistake during backup or do not follow the right procedure during restore. Thanks for helping me (and giving me a good sleep).
