I am looking to have a backup copy of my hard drive incase of failure. Ideally I would like this to backup nightly. I want to be able to have 2 HD's installed in the system at the same time and boot off of either drive if the other failed.
I have seen some solutions with DD, but I am not sure that that is the best way to handle this, as I tried it, but then could never get the drive to boot.
Currently I am trying this: How to upgrade my HDD and keep my ubuntu 11.10 instalation
But that doesn't run nightly.
I see this: How to replace my disk without having to rebuild my Ubuntu install? , but I tried this method only to get a drive that wouldn't boot. I didn't know how to get it to boot. Tried removing the original drive, but the "new" drive wouldn't boot after selecting it in the bios.
I am looking for a complete solution that backs up everything. This server has important data to me that I backup regularly, but I need to have a pretty quick way of restoring incase of a complete failure. Thanks in advance!
