As you can see, this is my first post to this forum, I have however read and sometimes re-read many of the thread posts. I purchased Acronis True Image Home 9.0 build 3677 and have burned my own Acronis True Image Bootable Media image (in ISO format) using the download link provided by Alexey of product support. One of the forum members here suggested that backup and restore were less problematic using the boot CD and that idea sounds reasonable to me, so I booted from the CD and set about backing up my system disk to an external USB drive. I selected full backup with the default settings and I assume this creates the backup with the 'active' option 'set'. Before completing the backup I selected cancel because I wasn't sure what one of the operations in the que meant. Right before starting the backup, Acronis lists the operations it will perform, and in my case it stated: Operation 1: backup from disk 1 C: to Emy USB drive) Then Acronis stated: Operation 2: Creating Partition Image Disk 1 Drive Letter C: System NTFS Volume Label Size 139.7 GB I'm not at all new to computers, or backup/restore operations, but this second operation raised the question in my mind as to what was being done to my C: drive, so I opted to cancel. To members of the forum who have more experience with this software this may seem trivial, but I don't understand what Acronis is doing here with operation 2, and I didn't see it explained anywhere. Does anyone on this forum know what this second operation does?
