Now here's the question. From within my live system, how could I compress my system into a compact image and then send it to a distant FTP server?
I'll answer this myself, since I just experimented and found a strikingly simple solution using dd and SSH (better than FTP).
Backup the server over the network from a live rescue session:
# dd if=/dev/sda status=progress | gzip --fast - | \ ssh microlinux@backup.microlinux.fr \ dd of=centos-7.9-server-image.gz
Restore this image from a live rescue session:
# ssh microlinux@backup.microlinux.fr \ dd if=centos-7.9-server-image.gz | \ gunzip --fast - | dd of=/dev/sda status=progress
As you mention “compress” in your question, you could also add -C flag to ssh command (to turn on compression)

Why didn't I think of this before ?
