About Clonezilla
Clonezilla boots from a USB stick and copies a disk or partition to an image file or straight to another drive. It reads ext, XFS, Btrfs, NTFS, FAT, HFS+ and more, and copies only the used blocks on those, which makes an image of a half-empty drive far smaller and faster than a raw dump. Anything it does not recognise falls back to a sector-by-sector copy, so nothing is left behind.
Clonezilla SE, the server edition, can push one image to dozens of machines at once over the network. There is no agent and no scheduler: it is a tool you boot into when you want an image, not something that runs in the background.
Strengths
- Images a whole drive including the boot loader, so a restore just boots
- Skips unused blocks on filesystems it understands, keeping images small
- Falls back to a sector copy for filesystems it does not know
- The server edition deploys one image to many machines over the network
Limitations
- You boot into it; there is no scheduled or background operation
- The destination drive must be at least as large as the source
- The text menu interface is unforgiving if you pick the wrong device
- No single-file restore; you get the whole image back or nothing
