1. A method of increasing disaster resiliency in a computer system, comprising:

  • executing, by a processor, an optimization algorithm that solves simultaneously for at least a first objective to increase a spread of a backup of virtual machines from a given site onto other sites in proportion to an amount of available space for backup at each site and a second objective to increase a number of backups at one or more of the other sites with low probability of system crash while reducing backups at one or more of the other sites with higher probability of system crash, the optimization algorithm minimizing a sum of the first objective that is weighted and the second objective that is weighted, the optimization algorithm being solved subject to at least data privacy constraints associated with at least the virtual machines to be backed up; and

    determining at least a backup site and a recovery site for the given site based on a solution of the optimization algorithm,further comprising transferring the virtual machines on one or more of the other sites based on a solution of the optimization algorithm to backup the virtual machines according to a frequency of backup determined based on a recovery point objective.
