Subject: How can I make an efficient backup or clone of my basic linux
from scratch (lfs) system?
What backup or cloning software should I use? Is dd sufficient? What is
the proper command for dd?
Currently i am using the following command only:
$ sudo dd if=/dev/sdb2
of=/home/teo-en-ming/teo-en-ming-linux-2020.03-final-dd.img
I created a bootable USB flash drive with Clonezilla on it. I boot from
this flash drive on several computers, including ones that host Linux
and Windows, and make a full drive backup. Clonezilla is smart enough to
skip over free filesystem blocks, so I'll bet it skips over the entire
contents of swap partitions. It also compresses the blocks it does save.
Actually for backup tar is sufficient.
tar -cJf .lfs-system.tar.xz /
On another system there may be some tweaks needed. Files like fstab and
whatever file sets th eIP address if it is not using dhcp.
You may want to exclude several directories: /dev, /lost+found, /mnt,
/proc, /run, /sys, and /tmp
