My first preference is <b>SystemRescueCD</b>. it is a bootable system rescue CD-ROM for PCs containing utilities that allow to manage and edit hard disk partitions. Needless to say that it takes image of hard disk partitions, a partition table backup and restore utility, various file system tools that allow to format, resize and edit existing partitions on hard disk.
U may go for “<b>Paragon Drive Backup</b>”. This is fully function able and the price is withing ur reach. Most probably around $49. It does not mean that, I am differing from other members, their suggestions are also good. Now it depends on u.
Hope it may help u !
