How to clone hard drives with Clonezilla

Nov 10, 2009, 14:03 (0 Talkback[s])

"Clonezilla supports a whole battalion of filesystems and then some. It can work its magic on partitions formatted as ext2, ext3, ReiserFS, XFS, JFS, FAT, NTFS, and HFS+, so you can let it rip on Linux, Windows, and Intel-based Macs. If Clonezilla encounters a partition type it doesn't understand, say Solaris's ZFS, it'll fire up the venerable dd and still get the job done. It'll constantly amaze you, so if you're looking for a bullet-proof way to backup your disks, read on...

"Big on saving

"Clonezilla not only saves your data, but also saves you a lot of time when doing so, by concentrating its efforts on stuff that matters - or segments of the disk that contain the data, and ignoring the blank space. But, unlike a simple data backup app, Clonezilla remembers the size of the partitions that you're asking it to clone.

"So, if you have a partially used 10GB NTFS partition, you can squeeze it in a 4GB pen drive, and yet when restoring it on another disk, ask Clonezilla to create the original 10GB partition. Oh, and it can compress this data using gzip, bzip2, or lzo compression algorithms. In theory it should take a lot of time to compress the data, but on the chic dual-cores juiced with a couple of GB of RAM, you'd hardly have time to make coffee. I cloned an 80GB disk with one NTFS, one FAT, three ext3, and a Solaris ZFS partition on to a 40GB USB disk in under 20 mins. And it took less than half that time to restore."
