Abstract
A technique for generating a crash consistent set of persistent consistency point image set associated with a storage space is provided. A client side agent obtains a first set of read/write statistics before causing storage systems to generate persistent consistency point images of volumes storing logical unit numbers comprising the storage space. Once the persistent consistency point images have been generated, the agent obtains a second set of read/write statistics. The first and second set of statistics are compared to determining if they are equal, thereby signifying that the set of persistent consistency point images is crash consistent.
