By default, automated purging of messages archived on the Barracuda Cloud Archiving Service is disabled. When enabled, the Global Retention Policy and any Saved search retention policies are run against all the archived messages once a day. You can allow messages to be deleted from the Barracuda Cloud Archiving Service when the age of any message exceeds the maximum age allowed by all matching Saved search retention policies, or the Global Retention Policy if no Saved search retention policy matches the message.
Note: The Global Retention Policy setting does not apply to any messages that match a Saved search retention policy.
To enable or disable the automatic message expiration capability:
Allow automatic message deletion
Specify whether to allow automatic policy-based message purging from the Barracuda Cloud Archiving Service.
Retention Policy
A Saved Search retention policy enables you to automatically expire messages that match a particular set of content criteria, namely a specified Saved search. Use this feature to create exceptions to the Global Retention Policy.
Important: When creating a new retention policy, saved searches with filters associated with tags, PST folder content, or discovery fields are unavailable. Saved searches of this type do not appear in the drop-down list of available saved searches when adding a retention policy.
Configure a Saved Search Retention Policy
Note the Saved search criteria on which this retention policy is to be based. If you need to create a saved search, go to the Basic > Search page. After you have created and saved a search, you can use it as part of a Saved search retention policy definition.
Verify that Allow automatic message deletion is set to Yes.
Click Add retention policy.
From the Saved search drop-down menu, select the name of the saved search on which to base this retention policy.
In the Keep on cloud section, specify whether to retain archived messages forever, or for a specified number of days:
Forever – Messages meeting the Saved search criteria on the Barracuda Cloud Archiving Service are retained forever.
For – Enter the number of days to retain archived messages that match the selected Saved search criteria.
Click Save to save the Saved search retention policy.
Note: If a message matches more than one Saved search-based policy, then the message is kept according to the longest policy length. If it matches a Saved search-based policy and the global retention policy, then the Saved search policy takes precedence.
The new Saved search retention policy displays in the Retention policy table.
Search Using a Saved Search Retention Policy
In the Retention policy table, click Search to run the selected Saved search query on which the policy is based. The Basic > Search page automatically displays with the matching search results.
Edit or Delete a Saved Search Retention Policy
In the Retention Policy table, click Edit to change the details of a policy, and then click Submit to save your changes. To permanently remove a retention policy, click Delete.
Global Retention Policy
The Global Retention Policy applies to every message in the archive. When retention policies are run against the archived messages (once a day), any messages stored on the Barracuda Cloud Archiving Service that are older than this age are deleted unless they match an existing Saved Search policy.
Configure the Global Retention Policy
Verify that Allow automatic message deletion is set to Yes.
Click Add Global Retention Policy to open the Add Retention Policy dialog.
In the Keep on box section, specify the total length of archived message retention:
Forever – Messages are retained on the Barracuda Cloud Archiving Service forever.
For – Enter the number of days to retain archived messages.
Click Save to save the Saved search retention policy.
Note: If a message matches more than one Saved search-based policy, then the message is kept according to the longest policy length. If it matches a Saved search-based policy and the global retention policy, then the Saved search policy takes precedence.
The new Global retention policy displays in the Retention policy table.
Edit the Global Retention Policy
In the Retention policy table, click Edit to change the details of the Global retention policy, and then click Save to save your changes.
Note: Making changes to the Global Retention Policy when Allow automatic message expiration is enabled may result in permanent deletion of some messages, especially if you are shortening the Policy Length.
Litigation Holds
Litigation Holds are created by auditors to prevent messages that meet the criteria for a specific Saved search from being removed from the Barracuda Cloud Archiving Service.
Select Enable Litigation Holds for auditors to create Litigation Holds from the Saved Searches tab on the Basic > Search page.
