EASEUS Disk Copy is a straightforward disk cloning tool that will quickly make a copy of the hard drive or partition you specify.
The program comes in the form of a bootable disc. When you launch it, you can have EASEUS Disk Copy burn its files to CD, DVD, a USB flash drive, or an ISO file (if you'd rather burn the disc using some other software). And you'll then need to boot from that disc or USB drive when you want to use the program.
While this is obviously a minor hassle, the program itself is just a simple wizard: choose whether you're copying a partition or an entire drive, specify the source and destination drives, and EASEUS Disk Copy will get on with copying your data at the fastest possible speeds.
There are a few restrictions and limitations here. If you copy the contents of a small drive to a larger one, for instance, Disk Copy won't resize the partitions accordingly. And the program doesn't support hard drives larger than 1TB, which could well be an issue for many.
If you like the program, though, EASEUS are hoping you'll upgrade to their Todo Backup packages, which rectifies these problems and adds many additional features (file backup, scheduled, incremental and event-based backups, backup to DVD and FTP server, and much more).
