When you have a dedicated back up drive and do scheduled backups does the new over write the old? Or do you go through the entire process again?
My image backup drives are 1TB each. The image files are exact images of my entire drive, not just files and folders, and currently average 125GB each.
In a program like Macrium Reflect, when you define a backup job and select the target folder on the backup drive, you can select how many versions to retain before it deletes the oldest one. So it does not automatically overwrite the last one unless you are low on space, or have the max versions set to 1.
Another convenience of the image file is that you can mount it as a virtual hard disk, which allows you to browse the entire file and folder structure in Windows explorer, with drag and drop copy to any other folder on your system. So if you do daily image backups, it makes file and folder backups rather obsolete. Plus it ensures that you get everything backed up.
And worse case if your hard drive fails, or your system won't boot one day, you can boot from the rescue media and restore your latest image, and be back up and running in minutes. Beats re-installing Windows, applications, and recovering your documents from backup media. That can sometimes take days.
