Clonezilla
Clonezilla is an open-source suite of disk cloning, disk imaging and system deployment utilities. Clonezilla Server Edition uses multicast technologies to deploy a single image file to a group of computers on a local area network. Clonezilla was designed by Steven Shiau and developed by the National Center for High-Performance Computing, NCHC Free Software Labs in Taiwan. Clonezilla is used to deploy operating systems to computers by imaging a single computer and then deploying that Disk image, image to one or more systems. It integrates several other open-source programs to provide cloning and imaging capabilities. Clonezilla works by copying used blocks on the storage device (i.e. SSD, SATA SSD, Hard disk drive, HDD or NVMe, NVMe SSD). It is intended to support a Bare-metal restore, bare-metal deployment of an operating system by booting from a Live CD, preinstalled live environment. The preinstallation environment can be booted from a Live USB, USB flash drive, Live CD, CD/DVD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partclone
Partclone is a partition clone and restore tool. It provides utilities to back up and restore partitions and is designed for higher compatibility of the file system library. It is developed by the NCHC Free Software Labs in Taiwan. It is the default backup application in Clonezilla, FOG (from version 1.00), Redo Rescue and Rescuezilla which is simply a front end to partclone. It supports many file systems and has good performance, as it skips portions of the file system marked as free space. Utilities Partclone currently supports the following filesystems: ext2, ext3, ext4, hfs+, reiserfs, reiser4, btrfs, vmfs(v3, v5), xfs, jfs, ufs, ntfs, fat(12/16/32), and exFAT. To run partclone for a particular filesystem, one uses the command 'partclone.', in a similar manner to the mkfs command * partclone.btrfs * partclone.ext2, partclone.ext3, partclone.ext4 * partclone.fat32, partclone.fat12, partclone.fat16 * partclone.ntfs * partclone.exFAT * partclone.hfsp * partclone.jfs * p ...

Disk Image
A disk image is a snapshot of a storage device's content typically stored in a file on another storage device. Traditionally, a disk image was relatively large because it was a bit-by-bit copy of every storage location of a device (i.e. every sector of a hard disk drive), but it is now common to only store allocated data to reduce storage space. Compression and deduplication are commonly used to further reduce the size of image files. Disk imaging is performed for a variety of purposes including digital forensics, cloud computing, system administration, backup, and emulation for digital preservation strategy. Despite the benefits, storage costs can be high, management can be difficult and imaging can be time consuming. Disk images can be made in a variety of formats depending on the purpose. Virtual disk images (such as VHD and VMDK) are intended to be used for cloud computing, ISO images are intended to emulate optical media, such as a CD-ROM. Raw disk images are use ...

Disk Cloning
Disk cloning is the process of duplicating all data on a Digital Storage, digital storage drive, such as a Hard disk drive, hard disk or Solid-state drive, solid state drive, using hardware or software techniques. Unlike file copying, disk cloning also duplicates the File system, filesystems, Disk partitioning, partitions, drive meta data and slack space on the drive. Common reasons for cloning a drive include; data backup and recovery; duplicating a computer's configuration for mass deployment and for preserving data for digital forensics purposes. Drive cloning can be used in conjunction with Disk imaging, drive imaging where the cloned data is saved to one or more files on another drive rather than copied directly to another drive. Background Disk cloning occurs by copying the contents of a drive called the source drive. While called "disk cloning", any type of storage medium that connects to the computer via USB, NVMe or SATA can be cloned. A small amount of data is read and ...

Partimage
Partimage is a disk cloning utility for Linux/UNIX environments. Partimage can save partitions in many formats to a disk image. Utilities such as Partimage are useful in a number of situations which are commonly encountered by network administrators as well as advanced computer users who maintain their own systems. The last stable release was in 2010; since then, one of Partimage's authors has worked on FSArchiver, which has broader functionality than Partimage. Common uses Some common uses for Partimage are as follows. * Backup of individual disk partitions. volume backups are very useful for recovery in the case of a disk failure or data corruption. * Large-scale operating system deployment. Organizations with multiple, similar computer systems may use Partimage or similar utilities to ease the process of operating system and software provisioning. Features For Windows users, Partimage includes experimental support for NTFS. Partimage supports most common Linux file syst ...

Live USB
A live USB is a portable USB-attached external data storage device containing a full operating system that can be booted from. The term is reminiscent of USB flash drives but may encompass an external hard disk drive or solid-state drive, though they may be referred to as "live HDD" and "live SSD" respectively. They are the evolutionary next step after live CDs, but with the added benefit of writable storage, allowing customizations to the booted operating system. Live USBs can be used in embedded systems for system administration, data recovery, or test driving, and can persistently save settings and install software packages on the USB device. Many operating systems including , , Windows XP Embedded and a large portion of Linux and BSD distributions can run from a USB flash drive, and Windows 8 Enterprise has a feature titled Windows To Go for a similar purpose. Background To repair a computer with booting issues, technicians often use lightweight operating systems on bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ntfsclone
Ntfsprogs was a collection of free Unix utilities for managing the NTFS file system used by the Windows NT operating system (since version 3.1) on a hard disk partition. 'ntfsprogs' was the first stable method of writing to NTFS partitions in Linux. All NTFS versions were supported, as used by 32-bit and 64-bit Windows. ntfsprogs was a popular way of interacting with NTFS partitions and was included by most Linux distributions and on Live CDs. There are also versions that have been compiled for Windows. On April 12, 2011 Tuxera announced that Ntfsprogs project was merged into NTFS-3G. See also * e2fsprogs * reiserfsprogs * Tuxera Tuxera Inc. (natively Tuxera Oy) is a Finnish company that develops and sells file systems, flash management and networking software.

Dd (Unix)
dd is shell command for reading, writing and converting file data. Originally developed for Unix, it has been implemented on many other environments including Unix-like operating systems, Windows, Plan 9 and Inferno. The command can be used for many purposes. For relatively simple copying operations, it tends to be slower than domain-specific alternatives, but it excels at overwriting or truncating a file at any point or seeking in a file. The command supports reading and writing files, and if a driver is available to support file-like access, the command can access devices too. Such access is typically supported on Unix-based systems that provide file-like access to devices (such as storage) and special device files (such as /dev/zero and /dev/random). Therefore, the command can be used for tasks such as backing up the boot sector of a drive, and obtaining random data. The command can also support converting data while copying; including byte order swapping and conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bare-metal Restore
Bare-metal restore is a technique in the field of data recovery and restoration where the backup, backed up data is available in a form that allows one to restore a computer system from "Bare machine, bare metal", i.e. without any requirements as to previously installed software or operating system. Typically, the backed up data includes the necessary operating system, Computer application, applications and data components to rebuild or restore the backed up system to an entirely separate piece of hardware. In some configurations, the hardware receiving the restore needs to have an identical configuration to the hardware that was the source of the backup, although virtualization techniques and careful planning can enable a bare-metal restore to a hardware configuration different from the original. Disk imaging applications enable bare-metal restores by storing copies (images) of the entire contents of hard disks to networked or other external storage, and then writing those images ...
