HDClone vs Relax-and-Recover

HDClone creates physical or logical copies and file images of hard disks and other mass-storage media. It works independently of partitioning schemes, file systems, and operating systems, including proprietary formats that might otherwise be inaccessible. For defective media, SafeRescue first skips damaged areas and then carries out the rescue operation. HDClone can make differential images containing changes to an original image, typically resulting in smaller files. Images can be optionally encrypted with AES and compressed, or saved in VMDK, VHD, VHDX, and VDI formats. Miray Virtual Disk can mount images, including VHDX and VDI, as Windows drives with read-only or writable access. HDClone supports Windows from XP through Windows 11, and an AppImage is available for Linux distributions. The self-booting package supports SecureBoot and includes boot-media creation setup for USB or CD/DVD. The free edition is for private use, supports up to 4 TB, and lists speeds up to 70 MB/s. Paid editions start at €19.90 once for Basic Edition.

Relax-and-Recover (ReaR) is a free, GPL-licensed Linux disaster-recovery framework from Relax-and-Recover, founded in 2006. It creates bootable recovery images for restoring systems to replacement physical or virtual hardware. The workflow rebuilds storage layouts, restores data through a backup program, and installs a boot loader. Recovery can be guided or fully unattended, including physical-to-virtual, virtual-to-physical, physical-to-physical, and virtual-to-virtual moves. Boot media includes ISO, USB, eSATA, bootable tape, and PXE. Built-in backup methods include tar and rsync, with integrations such as Bacula, Borg, Commvault, NetBackup, and Veeam. Supported storage technologies include RAID, LVM, multipathing, DRBD, iSCSI, and LUKS. ReaR is written in Bash with a modular design for extensions, and Disaster Recovery Linux Manager can centrally manage deployments. It must run as root, exposes no network services or ports, and version 2.9 was released in January 2025.
