Abstract: A technique of backing up a workload in a virtual environment includes identifying one or more files that are associated with the workload. One or more source volumes that include the one or more files are identified. A respective target volume is provisioned for each of the one or more source volumes identified. Only dirty blocks are copied (in a snapshot mode that prevents an update to the one or more source volumes during the snapshot mode) from each of the one or more source volumes to its respective target volume. The one or more dirty blocks are then copied from each target volume to a backup medium.
Abstract translation: 在虚拟环境中备份工作负载的技术包括识别与工作负载相关联的一个或多个文件。 识别包含一个或多个文件的一个或多个源卷。 为所识别的一个或多个源卷中的每一个提供相应的目标卷。 只有脏块被复制（在快照模式下，防止在快照模式下更新一个或多个源卷）从一个或多个源卷到其各自的目标卷。 然后将一个或多个脏块从每个目标卷复制到备份介质。
