Clonezilla vs Paragon Backup & Recovery

Clonezilla is a free, open-source program for imaging and cloning partitions and disks for system deployment, bare-metal backup, and recovery. Clonezilla live is suited to one machine; lite server and Clonezilla SE can clone many computers at once, with the site describing 40-plus computers. It saves and restores used blocks on supported file systems and uses sector-to-sector copying for unsupported ones. Listed file systems include Linux, Windows, Mac, BSD, Minix, and VMware formats, including ext4, NTFS, APFS, and VMFS3/5. Images can be kept on a local disk or SSH, Samba, NFS, or WebDAV servers, and can be encrypted with AES-256. Clonezilla SE supports multicast, while lite server supports BitTorrent deployment. Clonezilla live supports BIOS or UEFI boot and MBR and GPT. It requires an x86 or x86-64 processor, 196 MB RAM, and a boot device. The destination partition must be at least as large as the source. Differential and incremental backups and online imaging are not implemented; images cannot be mounted or explored for direct individual-file recovery.
