I have a 100G disk on an old redhat 7.3 system.
Filesystem Size Used Avail Use% Mounted on /dev/hda1 9.6G 2.4G 6.7G 27% / /dev/hda3 99G 6.1G 88G 7% /home hda2 is 2G swap
I am trying to back that complete image up on my centos 5 system. I can do the dd if=/dev/hda bs=1M | ssh root@machine 'cat > disk.img' which gets me the whole 100G.
As you can see most of the disk is unused. Is there a way to trim the resulting image to only be 10G instead of 100G?
Thanks,
Jerry
