PROTECTING DATA SEGMENTS IN A COMPUTING ENVIRONMENT

摘要

Exemplary method, system, and computer program product embodiments for protecting data segments by a processor device in a computing environment, are provided. In one embodiment, by way of example only, a history table is configured to accompany data segments for consultation during a replication operation. If the history table indicates an ownership conflict, the replication operation is inhibited.

主权项

1. A method for protecting a plurality of data segments by a processor device in a computing environment, comprising:
configuring a history table to accompany each of the plurality of data segments for consultation during a replication operation, wherein if the history table indicates an ownership conflict, the replication operation is inhibited; if an error occurs during the replication operation from a source location to a destination location causing at least one of a plurality of data segments to be deleted in the source location, performing:
executing a failback operation by a reverse replication process of the at least one of a plurality of data segments from the destination location to the source location, andregaining ownership of the at least one of a plurality of data segments by the source location; and pursuant to the failback operation, performing:
enabling the reverse replication process if an owner of the at least one of a plurality of data segments is a designated one of the destination location, andadding an invalid owner notification in the history table, wherein the failback operation is identified for the designated one of the at least one destination location.
