Abstract
Quality of service for secure workspaces having copy-on-write layers is provided. A priority filter can be loaded above an isolation filter and can be configured to evaluate I/O requests targeting copy-on-write layers to determine a priority of each I/O request. The priority filter can allow a high priority I/O request to be serviced immediately. In contrast, the priority filter can store a lower priority I/O request in a queue until high priority I/O requests have been serviced. In this way, an application in a secure workspace assigned a high priority will retain the ability to write data to its copy-on-write layer even when the copy-on-write layer is limited by a quota and other applications in the same or different secure workspace are consuming the quota.
