Abstract
Systems and methods for performing scheduled backups and recovery of data generated by one or more production applications operating on a MAGIC platform located on two or more host computers in a coherency group. The data for a coherency group is stored in a primary storage in the form of one or more production volumes and ISB protocol is used to create one or more clone volumes. Exemplary methods for backing up one or more clone volumes for a coherency group to a backup storage include copying the one or more clone volumes to a backup storage or creating a snapshot of the one or more clone volumes. The ISB functions of splitting and/or reconnecting the one or more production volumes and one or more clone volumes occur at substantially the same time for all the two or more host computers in the coherency group.
