Abstract:
1. A method for generating a set of persistent consistency point images of a plurality of volumes, comprising: coupling two or more computers together to form a cluster; organizing the plurality of volumes as a striped volume set, the plurality of volumes distributed across the cluster, and wherein each volume of the plurality of volumes is configured as a logical arrangement of one or more storage devices attached to at least one of the two or more computers; striping a data object across each volume of the striped volume set; setting a first marker for each volume of the striped volume set striped with the data object; in response to the setting of the first marker, completing in progress operations that modify the data object and holding newly received operations that modify the data object; and generating a persistent consistency point image of each volume of the striped volume set striped with the data object, wherein generating the persistent consistency point image of each volume of the striped volume set comprises,
