Partimage

About partimage

Partimage is opensource disk backup software. It saves partitions having a supported filesystem on a sector basis to an image file. Although it runs under Linux, Windows and most Linux filesystems are supported. The image file can be compressed to save disk space and transfer time and can be split into multiple files to be copied to CDs or DVDs.

Partitions can be saved across the network using the partimage network support, or using Samba / NFS (Network File Systems). This provides the ability to perform an hard disk partition recovery after a disk crash.

Partimage can be run as part of your normal system or as a stand-alone from the live SystemRescueCd. This is helpful when the operating system cannot be started. SystemRescueCd comes with most of the data recovery software for linux that you may need.

Partimage will only copy data from the used portions of the partition. (This is why it only works for supported filesystem). For speed and efficiency, free blocks are not written to the image file. This is unlike other commands, which also copy unused blocks. Since the partition is processed on a sequential sector basis disk transfer time is maximized and seek time is minimized ,Partimage also works for very full partitions. For example, a full 1 GB partition may be compressed with d own to 400MB.
