About policies for file systems
When a file system includes a cloud tier, you can use policies to control the movement of data between the on-premises storage and the cloud tier. A policy is a set of rules defined for a file system for deleting data or moving data. If you want to specify repeatable rules for maintaining data on the tiers, you can set up a policy for the file system.
Each rule defines the following criteria:
What action should be taken (move or delete)
When the data should be moved or deleted based on the access time or modified time of the file
Which data should be moved based on the pattern matching of the files and directories.
Each file system can have more than one rule, though you should be careful not to create rules that conflict or cause looping.
To move or delete the data, you run the policy. When you run a policy, the rules are applied to the data at the time the policy is run. By default, the policy does not run automatically. You can attach a schedule to a policy to have it run automatically at the specified times.
