Volatile Area Data Management Policy

The /volatile area is managed by an automated process that cleans up periodically in multiple steps as listed below. In the rules mentioned below the target threshold is defined as the "aggregate used space by all projects".

Cache manager policy

When a project is over their High Quota limit the following data backup and deletion policies will be enforced.

NOTE: You can pin files on /cache if you need to keep them available for an extended period. 

Please do not abuse the pin mechanism as /cache is a shared resource.
