Methods that can provide multi-layered data security in mobile personal computing devices are provided. One method includes assigning, by a processor, one of a plurality of security levels to applications of a mobile personal computing device, assigning one of the plurality of security levels to storage partitions of a storage device of the mobile personal computing device, and providing the applications access to data stored on the storage partitions based on a nexus of a first assigned security level for each application and a second assigned security level for each storage partition. Systems and apparatus that can include, perform, and/or implement the methods are also provided.

Multi-layered data security in mobile personal computing devices

A computer-implemented method includes receiving a request for storage for a container and determining whether a suitable thin provisioned volume currently exists based on criteria in the request. In response to determining that a suitable thin provisioned volume currently exists, the method includes selecting an unused portion of the thin provisioned volume and creating a container volume in the selected unused portion of the thin provisioned volume. The method also includes permitting input/output (I/O) to the container volume and releasing the selected unused portion of the thin provisioned volume in response to determining the container volume is no longer needed.
