Abstract
Methods for N-way mirroring of data to a plurality of distributed storage and systems for carrying out the methods are provided. One method includes initially selecting an initiator storage. The initiator storage is configured to have data that is to be protected. The method also includes selecting a group of storage. Each storage in the group of storage is configured to obtain an initial copy of the data of the initiator storage that is to be protected. A modification in the data that is to be protected in the initiator storage is then detected. The method accordingly proceeds to notify each of the storage of the group of storage regarding the modification. A detection of the notification is configured to cause each of the storage of the group of storage to independently copy the modification so as to maintain data consistency between the initiator storage and each storage of the group of storage.
