If you need close to real-time recovery, you need to have some sort of
live clustering with failover.  Just copying the images around will
take hours.  For the less critical things, I normally keep a 'base'
image of the system type which can be a file for a VM, or a clonezilla
image for hardware that can be used as a starting point but I don't
update those very often.   Backuppc just backs up the live files
normally for everything so for the small (and more common) problems
you can grab individual files easily and for a disaster you would
start with the nearest image master and do a full restore on top of
it, more or less the same as with hardware.
