Hi
I have 2 internal hard drives, each 1TB.
Both are partitioned into 2 500GB partitions.
Windows and the programs that have to be reinstalled if Windows changed (mainly Adobe their security is tough) are on Drive C:\.
May Games are on Drive D:\ the second partition of Drive 1.
Drive 2 has my Graphics files, video projects and software that doesn't have to be reinstalled if Windows on one partition and all my data and backups in the second.
In addition I have 3 external hard drives with all of my data backed up on at least 2 of them.
I only create the image file using the backup software to recover Windows if it crashes.
I don't back up any of my data, Music, Photos, Job Files and Software installers compressed, I just copy them to a backup drive.
The only time I've actually used my image file was when I upgraded to Windows 8.1 and had to go back to 8 again, because of sound issues I couldn't fix.
But it makes me feel a lot better knowing that the backup is there.
Before I make the backup I defrag the drive, and run every scanner I have to make sure the backup is perfect.
So at the worst, I can be back up and running in a half hour or so.
