Abstract: A fast mount cache is provided by any offline storage media for fast volume mount access. The fast mount cache may be used as the first level in a hierarchical storage configuration after the high performance tier for data having high access rates shortly after creation but decreases sharply as the data ages. The fast mount cache stores migrated data from online hard disk drive storage and maintains the data on a volume basis as opposed to a file basis. As the fast mount cache capacity fills, or other events occur triggering a volume change, the fast mount cache erases the volume having the oldest data. While data is maintained on the fast mount cache for periods of time soon after it is migrated, the data may be accessed quickly. After the initial period of time has expired, the data only exists on tape storage or low tier data.

Abstract: A preflight system for analysing an electronic document for possible problems is disclosed. The preflight system has one or more preflight clients and a preflight engine. Each preflight client is provided for an associated output component of the creation application and has testing code for testing one or more warnings relating to the associated output component. The preflight engine determines relevant preflight client, controls preflight process using the relevant preflight clients, and collects information on the test results of the warnings from the relevant preflight clients.
