# Advanced Retention Rules

Though every Snapshot Policy has a default record retention rule, it is often convenient to have a custom retention rule for specific tables. Example:

* By default, retain records in a snapshot for 90 days.
* Retain Account, Contact, and Opportunity records for 365 days.
* Retain Case records for 2 years.
* Do not retain EmailMessage records.

The following two screens illustrate how to set up this policy.

Clicking on the *Advanced* button launches an editor to override the default record retention rule. The following example sets up the scenario described at the top of this page.
