I am new to this forum and a novice user who wants to use Acronis True Image 2009. I have 3 partition of my 320 GB HDD i.e C,D,E. C: drive has only VISTA OS and no other data. While D and E drives has my data. Now I want to backup only C: drive as it contains OS by using Acronis True Image. So that in case of corruption of data or due virus attack i can only restore C: drive without affecting other drives i.e D and E. My queries are as follows: Do Acronis allow to take backup of only single partition ?Here in my case only C: drive. When I restore the backup of C:drive does it effect other drives?(I mean here that whether it affect drive data from being accessible after restore) When Acronis restore backup image, does it formats the drive and then restores the image or it just overwrites the drive.(If overwrites the drive then if C: drive has virus the it will create problem. Please clarify) Please help me for said things and also guide me how to proceed. If possible please provide me links to tutorials.
