Clonezilla

Apakah Clonezilla?

Barangkali kita cukup familiar dengan Norton Ghost® yang lumayan populer. Masalah utama dengan software ini adalah membutuhkan wkatu lama untuk melakukan cloning ke banyak komputer sekaligus. Kita mungkin juga pernah mendengar solusi Symantec pada masalah ini menggunakan Symantec Ghost Corporate Edition® dengan multicasting.

Nah, pada saat ini kita dapat menggunakan solusi OpenSource clone system (OCS) bernama Clonezilla dengan unicasting dan multicasting!

Clonezilla, berbasis DRBL, Partclone dan udpcast, yang memungkinkan kita untuk melakukan backup dan recovery. Ada dua (2) jenis Clonezilla, yaitu, Clonezilla live dan Clonezilla SE (server edition). Clonezilla live dapat digunakan untuk backup dan restore untuk sebuah mesin. Sedang Clonezilla SE dapat digunakan untuk mendeploy secara masif, dia dapat melakukan cloning banyak (40+) komputer secara bersamaan. Clonezilla hanya akan menyimpan dan me-restore blok yang digunakan di harddisk. Hal ini akan sangat meningkatkan effisiensi proses cloning. Pengalaman menunjukan akan membutuhkan sekitar 10 menit untuk mengclone 5.8GB sistem image ke 41 komputer menggunakan multicast!

Fitur

• 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.

Keterbatasan

• The destination partition must be equal or larger than the source one.
• Differential/incremental backup is not implemented yet.
• Online imaging/cloning is not implemented yet. The partition to be imaged or cloned has to be unmounted.
• Software RAID/fake RAID is not supported by default. It's can be done manually only.
• Due to the image format limitation, the image can not be explored or mounted. You can _NOT_ recovery single file from the image. However, you still have workaround to make it, read this.
• Recovery Clonezilla live with multiple CDs or DVDs is not implemented yet. Now all the files have to be in one CD or DVD if you choose to create the recovery iso file.

Clonezilla mana yang harus kita gunakan?

• Clonezilla Live: Clonezilla live allows you to use CD/DVD or USB flash drive to boot and run clonezilla (Unicast only)
• Clonezilla SE: Clonezilla SE is included in DRBL, therefore a DRBL server must first be set up in order to use Clonezilla to do massively clone (unicast, broadcast and multicast are supported)
