In the GZIP/BZIP2 formats to save disk space, and split into multiple files. (Ext2, Ext3, NTFS, FAT32, etc) to an image file. Partition Image saves partitions or whole disks for the most common filesystems formats On Linux Partimage is analog of Gnome and is usable with ext filesystem up to ext3. It contains deleted files and can be used for recovery of those files instead of the disk. Utility ddĬopies the whole partition or the whole disk indiscriminately which make the image larger, although They understand what part of the disk belongs to the filesystem and which don't. Ghost andĪcronis True Image are better tools for that. In Windows dd command can do backups and restores to the same disk, but there are some In the latter case using cp command would not be sufficient becauseĭata from deleted files still physically present on a disk but are not visible in the file system naming Used to recovery of deleted files and in computer forensics when the contents of a disk need to be preservedĪs a byte-exact copy. DD uses older approachĪnd includes into image parts of the disk that are not parts of the filesystem. The key idea is to get an image of the partition in the form of the file. It served as an inspiration to the most important recent class backup programs called

There is also native Windows Win32 port of dd (see

dd is also available for Windows as part of The GNU clone of dd is part of fileutils package and was written by Paul Rubin,ĭavid MacKenzie, and Stuart Kemp. Complex setups involving LVM are more difficultĭD also can be use for recovery of files on Windows filesystems, especially FAT32. More chances you have to recover information. Recently capability to mountĭd-images was added to Linux and other Unixes.ĭD is very important tool for recovery of Unix filesystem. Linuxes you can mount dd image using loopback interface. The if and of parameters, may accidentally render the entire disk unusable. It is jokingly said that dd stands for ' destroy disk' or ' deleteĭata', since, being used for low-level operations on hard disks, a small mistake, such as reversing The name is an allusion to IBM/360 mainframe It proved to be an indispensable Unix tool. The dd command has been around since the 1970s, ported to many systems, rewritten many (slightly skeptical) Educational society promoting ' Back to basics' movement against IT overcomplexity Softpanorama May the source be with you, but remember the KISS principle -)
