Clonezilla(क्लोनझिला)

क्लोनझिला (Clonezilla) हे एक मोफत डिस्क क्लोनिंग सॉफ्टवेअर आहे. क्लोनझिला वैशिष्य म्हणजे ते निरुपयोगी रिकामी मेमरी सोडून फक्त वापरलेल्या मेमरीचाच बॅकअप घेते आणि ते रिस्टोअर करण्यास मदत करते. क्लोनझिला दोन प्रकारांमधे उपलब्ध आहे. क्लोनझिला लाईव्ह (Clonezilla Live) आणि क्लोनझिला सर्वर (Clonezilla Server Edition); फक्त एखाद्या पर्सनल संगणकाला क्लोन करावयाचे असल्यास क्लोनझिला लाईव्ह वापर करता यतो आणि जर अधिक संगणकांचे  क्लोनिंग करावयाचे असल्यास क्लोनझिला सर्वर (Clonezilla Server Edition) उपयुक्त ठरतेक्लोनझिलाची Multicast  सुविधा डझनभर संगणकांना एकाचवेळी क्लोन करु शकते त्यामुळे डिक्स क्लोनिंगचे काम एकऊणच जलद गतिने परिणामकारक्रित्या होते.
वेळोवेळॉ असे प्रसंग येतात की आपण संगणकावरील डेटा हरवून बसतो किंवा कधीकधी एका मशिन वरची ऑपरेटीग सिस्टीम इतर संगणकांवर कॉपी करण्याची गरज असते अशा कामांसाठी क्लोनझिला हे ओपनसोर्स सॉफ्टवेअर नक्की उपयुक्त आहे.

Clonezilla is a free disaster recovery, disk cloning, disk imaging and deployment solution. It saves and restores only used blocks in hard drive.
CloneZilla comes in 2 modes:
1.     Clonezilla Live -  'Clonezilla Live' enables a user to clone a single computer's storage media, or a single partition on the media, to a separate medium device. The cloned data can be saved as an image-file or as a duplicated copy of the data. The data can be saved to locally attached storage device, a SSH server, Samba Server or a NFS file-share. The clone file can then be used to restore the original when needed. The Clonezilla application can be run from a USB-flash-drive, a CD-ROM, or a DVD-ROM. Clonezilla requires no modification to the computer; the software runs in its own booted environment.
2.     Clonezilla Server -  Clonezilla Server is used to clone many computers simultaneously across a network. This is done using a DRBL server and computer workstations that can boot from a network.


CloneZilla Features:
  • Free (GPL) Software.
  • Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs of GNU/Linux, (2) FAT, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, and (5) VMFS of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, and FreeBSD, NetBSD, and OpenBSD, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
  • LVM2 (LVM version 1 is not) under GNU/Linux is supported.
  • Grub (version 1 and version 2) is supported.
  • Multicast is supported in Clonezilla SE, which is suitable for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
  • Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition. However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.
