doClone vs OSFClone

doClone is a free GNU/Linux program for creating and restoring disk or partition images, including transfers between computers on a local network. It can image the system it is running on, clone disks or partitions of different sizes, and preserve filesystem UUIDs and labels. When restoring to a differently sized disk, it can resize partitions proportionally; a smaller target works only if the stored data fits, otherwise restoration returns an error. Full-disk images include the boot sector, and doClone can restore GRUB and its options on the receiving machine. Network transfers can use Unicast/Multicast or Chain Mode, which moves data through a chain of computers. The program supports 12 filesystems, including ext2, ext3, ext4, FAT16, FAT32, HFS, HFS+, JFS, Linux swap, NTFS, ReiserFS, and XFS, plus nine disk labels. Local use is limited to creating images and restoring existing ones. The project describes managing GNU/Linux installations in offices or schools, including computers with different hardware. It has so far been compiled only for GNU/Linux. The listed latest version is 0.8.0; dependencies include libparted 3.2 or later and several other libraries. It is distributed under the GNU GPL v3 License.

OSFClone is a free disk-imaging utility that boots from CD/DVD or USB and creates or clones disk images without relying on the installed operating system. It supports raw images and AFF, EWF, and dc3dd formats. The maker says images preserve unused sectors, slack space, file fragmentation, and undeleted file records. Users can compare a clone with its source using MD5 or SHA1 hashes, compress images, and attach forensic metadata such as case and evidence numbers, examiner name, description, and checksum. The product page describes cloning FAT, NTFS, and USB-connected drives. Its listed current download is a 373 MB ZIP for version 1.4.1000; USB installation needs a drive of at least 2 GB. The maker cautions that hardware, driver, and disk-state differences may contaminate evidence, and flags possible superblock changes when ext2/3/4 evidence drives are connected during startup. Some UEFI systems may not boot OSFClone. The software is licensed under GPL v3.0; its images can be mounted with PassMark OSFMount and analyzed with PassMark OSForensics.
