XXCLONE duplicates the whole Win NT, 2000 or XP system volume to another volume that will become ready to boot without a restore step. You may boot the system from the clone volume by simply swapping the disks when a disaster strikes. The cloned volume may be larger than the source volume, or even smaller as long as the volume data can fit. You may copy from FAT to NTFS or vice versa. It supports USB-disk, PATA and SATA. Ideal for periodic backup, or a one-time disk upgrade, or migration. Unlike the disk imaging tools, XXCLONE copies files and directories. Therefore, you stay in Windows and may do some work while the cloning runs in the background. With a full volume backup, files in the target volume will always de-fragmented automatically without the need for the time-consuming de-frag on the source. It maintains Restore Points with most recent 7 daily, 4 weekly, 12 monthly and 5 yearly records with which you can restore the exact state of the system registry. Additional features include tools to duplicate the Volume ID, to repair non-bootable disk, and more. It supports command line arguments and suits batch file invocations, also. Extremely easy to use with user-friendly GUI.
