some Unix notes
You can create a file to exclude all the patterns you need
# cat x.txt
/proc/*
/dev/*
/run/*
/tmp/*
/sys/*
/mnt/*lol
/media/*
/lost+found
/var/lib/origin/
/gbt/
/registry/
*log
Then just rsync
# rsync -rtva –progress / 10.156.197.10:/a/ –exclude-from x.txt
These are the directories to mount:
# mount -o bind /proc /a/proc
# mount -o bind /dev /a/dev
# mount -o bind /sys /a/sys
# mount -o bind /run /a/run
# chroot /a /bin/bash
Once in, you may update your grub, but please check /etc/fstab before…
# grub2-install /dev/sda;grub2-mkconfig -o /boot/grub2/grub.cfg
# rsync -av -f”+ */” -f”- *” /var/ 10.156.197.10:/a/var/
