Preventing excessive hydration in a storage virtualization system

Abstract:

Storage virtualization techniques allow files and directories to be stored remotely, for example, by a cloud storage provider, but in a manner that appears to a user or application running on a local computing device as if the files are stored locally--even though the data of those files and directories may not be resident on the local computing device. That is, the contents of files and directories that may exist in the cloud look and behave as if they were stored locally on a computing device. The level of hydration of placeholders may be monitored and operations may be performed to reduce the impact of excessive hydration on the resources of the computing device.
