Hi TG,
You can keep an up-to-date copy of the files/folders/pipes/etc. in the
100GB space using rsync, but not a true clone of the partition.
To get a true clone of the boot partition, you'd need to boot from a
rescue CD, mount the other machine's 100GB space and dd the boot
partition device to a file on the 100GB space.
You'd also probably want to get the Master Boot Record by grabbing the
first 2K of the raw boot device into a separate file...
i.e. something like:
dd bs=512 if=/dev/sda1 of=/mnt/u/backup/jessie_sda1
dd bs=512 count=4 if=/dev/sda of=/mnt/u/backup/jessie_mbr_sda
The device names might be different - the mount folder may be different
- etc...
But the idea works. - With a new, blank drive, you could recreate the
partitions using fdisk, reverse the dd commands, boot and then work on
getting the second partition back up and running.
