How you would set up an automated nightly backup for the whole disk (boot and data partition) running Ubuntu Server?
I have a 1TB drive (current usage 200GB) and I want to have daily clone of this drive on another drive (the same capacity and model), on the same machine.
I was previously running dd
to have partition backup. But now I'm looking for some bulletproof solution to have a HDD clone to switch to in case of crash.
RAID is not an option, as when something is broken/deleted on the first drive, this happens on the other drive too (I know I should have RAID + the backup solution).
Copying the whole 1TB would take some time, so I'm looking for a tool which is able to find the daily differences and just update them.
The other problem is that that I need the clone of the whole disk (both partitions - ext2 and lvm + the boot record).
How would you set up this?
