Abstract
System and method for policy-based lifecycle management of data in file systems. In embodiments, an expiration policy for the files may be stored as part of the file system metadata. The expiration policy may be as simple as an expiration date for the file, or a more complex policy that specifies one or more metrics to be evaluated to determine if a file is expired. The expiration policy may also specify one or more actions to be taken if the file has expired. The expiration policy may be evaluated on attempts to access the files in the file system, on other file systems, and on backup/archive images to determine if the files are expired and thus whether access to the files is to be allowed. In one embodiment, a scan mechanism may periodically or aperiodically delete files in the file system for which the expiration date has passed.
