SharePoint 2019 OnPrem Site Collection Audit Settings

Question

I had some questions regarding SP 2019 OnPrem site collection audit settings:

1. Where is Audit report data stored? Is it on Database? If yes, what are database name?
2. When you specify No for "Automatically trim the audit log for this site? ", will audit report keep indefinitely?

Thanks

Hi @TN ,

To answer your questions:

1. SharePoint audit logs data are stored on the AuditData table inside the content database of the site collection. You need to be careful which events you track and how you configure the audit log trimming to avoid using excessive disk space for audit logs.
2. No, the default setting for retaining audit log data is zero days. That means if you don't specify a different retention period, all audit log entries are deleted at the end of the month.

In addtion, we can also specify the document library to save audit log reports to before the audit log data is trimmed. Set this option if you need access to audit log data, using audit log reports, after the audit log has been trimmed.

The audit log reports can be stored in the document library indefinitely.
