How to Backup Linux Filesystem Using Clonezilla
Clonezilla is a free, disaster-recovery open source backup tool. Clonezilla helps us to take a clone of a single drive or a single partition within the drive and then recover it in future if required. You can also backup entire disks or individual partitions remotely (using SSH, Samba or NFS shares). If filesystem gets failed so you can easily restore the filesystem on the same system or into some other machine.
Filesystem clone is the process of copying data from a hard disk to another hard disk. If you copy & paste data manually then it won’t be able to copy the hidden files and folders. In this article, we will explain to you how to take a backup of a filesystem.
Limitations:
- The destination partition must be equal or larger than the source one.
- Incremental backup is not implemented yet.
- You can’t clone drive while the system is running because cloned can be taken when the filesystem is unmounted.
- Recovery Clonezilla live with multiple CDs or DVDs is not implemented yet.

Before doing the real cloning, Clonezilla will ask confirmation.
First, it creates the partition layout in the target Disk and then Clonezilla starts cloning the data from source disk to the target disk.
Now choose Poweroff or Reboot
Now the Source Disk has been Cloned to Target Disk successfully and target disk is ready to use.
Enjoy it!
