Clone/backup using clonezilla

Is there a way to take a system image backup or to restore before booting into the system. Eg. Using clonezilla or a startup disk. I have used DD command but it isn’t so reliable when running a live system. I have made a clonezilla startup disk on an SD card, but it didn’t want to boot.

You must decide if you want to make live copy or offline copy. If you need live copy - the solution is rsync.

If you want an offline copy dd + eventually gzip is the right choice.

I am making backup copy of my SD card in Windows by Win32DiskImager and then compress it with WinRAR. You can also use Cygwin to do the copy and 7-zip to compress it.

Dd copy is always very big and you may want to zero free space on filesystem before making such a copy to compress it better.

I am using rsync to backup all important files into mounted folder which is my pendrive:
rsync -aAXv / --delete --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /mnt/bak


Thanks pbies

I will check out rsync. It sounds like the option I need.
