I cannot find the Log Retention settings in the small business manager. I have seen many guides that state it is in the Computers - Policies - Virus and Spyware - Miscellaneous, but I don't have a miscellaneous tab. Any help would be greatly appreciated.
Please check under Admin >> Servers, select your database server and select Edit Database Properties
Check on the Log Settings tab
Under Admin I only have Administrators, System, and Licenses.
Looks like SEP SBE does not have log retention, see here:
What is the Log Retention period in the Symantec Endpoint Protection Manager Small Business Edition 12.1
By default, logs are kept for 60 days.
