# Check and compare Policy Snapshots

You can compare two policy snapshots, or check which policy was in place at a particular time.

##

Each time a policy is successfully installed, a record of that configuration is stored in the upload history. These policy snapshots enable you to the check which policies were uploaded and when, and allows you to run an automatic check for policy refresh needs.
Note: The policy snapshot is only stored when the policy is successfully installed. No snapshot is stored if the policy installation fails.
