Abstract
Techniques are provided to manage data on shutdown of a data storage system. For example, a method comprises initiating a process to shut down a data storage system which comprises storage devices that store data associated with one or more non-persistent logical storage resources of a virtual storage layer which is configured by the data storage system. In response to initiating the process to shut down the data storage system, the method comprises: storing configuration data associated with the virtual storage layer, the configuration data comprising unique identifiers associated with the one or more non-persistent logical storage resources; and performing a data backup process to persistently store a copy of the data associated with the one or more non-persistent logical storage resources to a backup storage system.
