  1. I don’t understand all this technical stuff. I used to use AOMEI backerupper. That cloned my 1TB disk onto another 1TB disk, which I could then uses to boot Windows by altering the priority in which the computer startup looks at the disks. It worked well, and was so simple.
    Unfortunately it only handles up to 3 disk partitions. I have six partitions.
    Is there an open-source program that will do the same for me with more partitions as AOMEI?
    It sounds as if Clonezilla might work, but then they go off and talk about two stages to restore. Is there anything that will produce an exact copy of my hard drive, that will run by booting up the copy?
    I do NOT want to create a new hard drive with folders instead of partitions and transfer each partition into the appropriate folder. That would allow me to use AOMEI – supposedly creating an entire clone an a quarter of an hour so that I can clone my hard drive twice each evening, and keep the clones in two different locations with no chance of having to re-install windows in case of a crash.

  2. Thanks. Which one is easiest to use for Windows home computers backing up to external HDs? I’m looking for something that can backup a system image with daily incremental backups, delete the oldest backup set if the HD becomes full (i.e., set-and-forget), and use a rescue disk to restore the system in the event of a major crash.

    • Hello Monk,

      Most of the software available for Windows personal desktop backup with incremental or differential backup are not totally free. You can try AOMEI Backupper …
