The 'rear' (Relax-and-Recover) package from EPEL is about as easy to
use but with a different approach. It will generate a bootable iso
containing a script to reconstruct the partitions, filesystems, etc.
and restore to them. Some tradeoffs are that Clonezilla will do
single disks and bring along windows or other partitions not part of
the active system, but can't handle multiple drives or RAID and it
needs at least an equal-sized disk for the restore. ReaR can make
its backup without shutting the running system down, understands
raid/lvm, etc., but only the linux filesystems - and with some work
you can modify the disk layout/sizes before the restore. ReaR is a
reasonable tool to do conversions to VM's, etc., where you are likely
to want to rearrange the layout or remove software raid, although you
have to manually edit the layout description file.
