Clonezilla

When you need a clean, byte-for-byte snapshot of a system, speed matters more than bells and whistles. Boot the live environment from a USB stick, pick whether you want to clone a whole disk or just a partition, and decide where to store the image—an external drive, a network share, or another internal disk. For a one-time upgrade (e.g., HDD to SSD), first capture an image with compression enabled, verify it, then restore it onto the new drive and expand the filesystem to fill the extra space. If the target is smaller, shrink partitions on the source beforehand with a partitioning tool, image again, and restore. Always include the bootloader and partition table so the restored machine starts correctly on both BIOS and UEFI systems.

For ongoing protection, create a repeatable backup routine. Keep a labeled folder per machine and add date-stamped images for each run. Store them on a NAS or external disk, encrypt the archives if they leave the building, and enable checksum verification to catch corruption early. Use the unattended mode to script the entire flow: mount a share, capture the system drive, verify, and shut down. Pair this with a maintenance window so desktops, kiosks, or POS terminals can be rolled back to a known-good state in minutes when updates misbehave. To keep image sizes lean, exclude swap, choose a faster codec like zstd when available, and archive logs and temporary files before imaging. more
