Hello,
a few years ago (I believe it was March this year ...) I asked for ideas
concerning an easy raw iron restore of a Linux based spectrometer computer.
Most reponses mentioned CloneZilla. Unfortunately I am not really happy with this
software. The biggest issue is the treatment of LVM (logical volume management).
Although according to the project homepage, CloneZilla should be able to
recognize LVM, I failed repeated times. It is possible to do 1:1 cloning, but for this
I don't need CloneZilla. A simple dd will do the same.
One nice idea was the annual 1:1 copy of the actual running hard disk, keep the new and store
the old as backup.
I tried by myself to use RAID-1. This should be a hard RAID-1 using LSI controllers.
The reason is, that I have a supervising scheme for a number of these controllers here,
which works fine. But thinking about this, it means to have a look for a mainboard with
three PCIe slots (NIC, graphics, RAID controller). I found one, but this
didn't work under centOS 6.4, although newer Fedora distributions worked fine.
Finally I ended using the good old Acronis TrueImage. Release 2014 recognizes ext4 !!
It doesnt recognize LVM but is able to create compressed images from unrecognized partitions
like that LVM ones. Its possible to create and restore using an USB stick as boot medium
and move the data using a CIFS network share.
There is only a really tiny issue. Although the USB stick works fine using one license for multiple
machines, one should be fair and purchase licenses for each machine. But you cannot
purchase "license only". Only full packages.
