Drive Backup will help you upgrade your hard disk.
Drive Backup transfers all data - operating systems, applications, files - from old hard disk to the new one. Every file and directory will be copied. No need to reinstall operating system - boot areas also will be copied. New hard disk can have different size and geometry- partition size will be adjusted to the new hard disk size during copy.
Drive Backup - secure the whole system or system partition.
It will take a lot of time to recover your system - re-install operating system, application - in case of failure or virus attack. Even application installation can affect your OS. The best way to secure the system - backup everything including system information. Or you can backup only system partition with OS installed. Backup can be performed to the hard disk, to the removable media (ZIP, JAZ, LS120, Sequest, CDROM), to the network.
