I'm looking to set up regular system backup of my 750GB hard drive (windows 7) onto an external HDD. FOr this purpose I've purchased a 2TB eHDD which I'd like to partition (one partition to back up the 750GB, one as additional storage or to back up other computers running XP). From what I've read the partition on which the system will be backed up needs to be larger that the original hard drive. Does this mean I should partition the 2TB eHDD into 2x1TB partitions? I was planning on using the Windows 7 System Image to perform the regular backups.
